! WARNING !

- Do NOT proceed before reading -

This manual must be carefully read by all

individuals who have or will have the responsibility

for using, maintaining, or servicing this product.

The product will perform as designed only if it is used,

maintained, and serviced in accordance with the manufacturer's

instructions.

CAUTION!!

To reduce the risk of electric shock, turn off power

before removing the monitor cover. Disconnect the

removed. Remove monitor cover and sensor

module only in an area known to be non-hazardous.

CAUTION!!

The model PGM-7200 equipment is classified as to

intrinsic safety for use in class I, division 1, groups

A, B, C, D, or non-hazardous locations only.

Special Notes

-1-

When the UltraRAE Monitor is taken out from the

transport case and turned on for the first time, there may be

some residual organic or inorganic vapor trapped inside the

detector chamber. The initial PID sensor reading may

indicate a few ppm. Enter an area known to be free of any

organic vapor and turn on the monitor. After running for

several minutes, the residual vapor in the detector chamber

will be cleared and the reading should return to zero.

-2-

The battery of the UltraRAE monitor will discharge slowly

even if it is turned off. If the monitor has not been charged

for 5-7 days, the battery voltage will be low. Therefore, it is

a good practice to always charge the monitor before using it.

It is also recommended to fully charge the monitor FOR AT

LEAST 10 HOURS before first use. See Section 7 for more

information on battery charging and replacement.

-3-

The instrument default condition for the tube barcode

reader is to be “OFF”. In this condition, once a tube is

selected, the instrument assumes that the same type of tube

will be used until a different tube type is programmed.

CAUTION

If the incorrect tube type is programmed or the Measure

Wait Time is otherwise set too short, it is possible to

underestimate the VOC concentration and thereby cause

overexposure. The automatic barcode reader can be enabled

in the program mode (see Section 4).

2.3 Power On/Off

To turn on the UltraRAE Compound Specific PID monitor,

press [MODE] key for one second and release. The audio

buzzer will beep once and the display will show “ON!..” and

then “Ver #.##” to indicate the unit’s current firmware version

number. The model number, current date and time, unit internal

temperature, last calibration date and time, battery voltage, and

shut off voltage are displayed.

To turn off the UltraRAE Compound Specific PID monitor,

press and hold the [MODE] key for 5 seconds. The monitor

will beep once per second during the power-down sequence

with a count down timer showing the number of remaining

seconds. The message “Off!..” flashes on the LCD display and

the display will go blank indicating that the monitor is turned

off.

Data protection during power off

When the monitor is turned off, all the current real time data

including last measured value are erased. However, the datalog

data is preserved in non-volatile memory. Even if the battery is

disconnected, the datalog data will not be lost. During power

off period, the real time clock will continue to operate until the

battery is completely drained (usually in 5-7 days without any

charging). If the battery is completely drained or is

disconnected from the monitor for more than 30 minutes, the

real time clock will be lost. In this case, the user needs to enter

the real time clock information again, as described in Section 4,

or send the PC clock during configuration.

CHANGE CURRENT TUBE TYPE [Only in the default

condition where the barcode reader is turned “Off”]: The

present tube type is displayed e.g., “Benzene?” and can be

altered by pressing [N/-] until the desired tube type is displayed.

Press [Y/+] to accept the displayed tube. With the barcode

reader “Off,” the instrument assumes that the same type of tube

will be used until a different tube type is programmed. It is

important to select the tube type correctly because this

determines the lamp required and the measure wait time.

!! CAUTION !!

If the incorrect tube type is programmed or the Measure

Wait Time is otherwise set too short, it is possible to

underestimate the VOC concentration and thereby cause

overexposure.

This menu item is not displayed when the barcode reader is

enabled (to enable see Section 4.7.9).

BATTERY: The menu displays the present battery voltage.

Note: A fully charged battery pack should show 4.8 volts or

higher. When the battery voltage falls below 4.4 volts, a

flashing “Bat” will appear as a warning message. When the

battery voltage falls below 4.2 volts, there are about 20-30

minutes of run time left before the monitor turns off

automatically.

Start Measurement

Press the [Y/+] key to start the measurement cycle. The pump

will start and the remaining wait time will be displayed. If a

VOC tube is inserted, the real-time ppm measurement will be

display. The total pump time is the sum of the pre-programmed

optimum time and the user programmable “measure wait time”.

At the end of the waiting period, the measurement value will be

logged, if enabled. At this point the monitor will alternately

display the measurement value and “Done!”

If no tube is inserted or detected, the [Y/+] key can be pressed.

The “Manual select?” message will be displayed. Press the

[Y/+] key again to confirm a manual tube selection. The first

tube name, of the currently configured tubes, will be displayed.

Press the [Y/+] key to accept this tube name or press the [N/-]

The sampled reading is the actual gas concentration in parts per

million (ppm) for that gas. The reading is held and displayed

until the user presses a key to move on to the next display.

Tube Removal

Press the [Y/+] key to advance to the next phase. The monitor

will next display the prompt “Remove tube!” (if a tube is

present). Remove the tube to return to the “Ready…” prompt.

Abort Measurement

During waiting period, any key pressed will abort the

measurement.

OPERATION

2 - 12

2.5 Alarm Signals

At the end of each measurement period, the gas concentration is

compared with the programmed alarm limits (two gas

concentration alarm limit settings: Low & High). A separate

set of limits can be programmed for each tube. If the

concentration exceeds either of the preset limits, the loud buzzer

and red flashing LED are activated immediately to warn user of

the alarm condition.

In addition, the UltraRAE will alarm if one of the following

conditions occurs: battery voltage falls below a pre-set voltage

level (4.4 V), failure of UV lamp, pump stall, or when the

datalog memory is full. When the low battery alarm occurs,

there will be approximately 20-30 minutes of operating time

remaining. When the battery voltage falls below 4.2 V, the

monitor will be turned off automatically.

VOC 100.0 ppm 50.0 100.0

OPERATION

2 - 15

2.7 Integrated Sampling Pump

The UltraRAE Compound Specific PID monitor includes an

integrated sampling pump. This is a diaphragm type pump that

provides 400-500 cc per minute flow rate (with no tube in

place). Connecting a 1/4 inch Tygon tubing with 1/8 inch

inside diameter to the gas inlet port of the UltraRAE, this pump

can pull in air sample from 200 feet away horizontally, or 90

feet vertically, at 3 feet per second flow speed.

The pump is turned on when a measurement is manually started

by the operator and turns off automatically at the completion of

the sample.

If liquid or other objects are pulled into the inlet port filter,

causing the pump to stall, the monitor will detect the

obstruction and shut down the pump immediately. The alarm

will be activated and a flashing error message “Pump” will be

also displayed on the LCD display.

The user needs to acknowledge the pump shut off condition by

clearing the obstruction and pressing the [Y/+] key to re-start

the pump.

OPERATION

2 - 16

2.8 Backlight

The LCD display is equipped with an LED backlight to assist in

reading the display under poor lighting conditions. In manual

mode, the backlight can be turned on by pressing and holding

the [N/-] key for one second in normal operation. The backlight

can be turned off by pressing [N/-] a second time. If the [N/-]

key is not pressed, the backlight will be turned off automatically

after a pre-programmed time-out period to save power.

In automatic mode, the ambient light is sensed and the backlight

will be turned on automatically if the ambient light is below a

threshold level. The backlight will be turned off automatically

when the ambient light exceeds the threshold level.

(See Section 8.1 for instructions on how to set the threshold

level.)

Note: The LED backlight consumes about 20-30% of the total

average current, when the instrument is idle or not taking a

measurement.

OPERATION

2 - 17

2.9 Datalogging

The UltraRAE Compound Specific PID monitor stores the time

stamp, sample number, tube name and measured gas

concentration at the end of every sample period (when data

logging is enabled). In addition, the following information is

stored: user ID, site ID, serial number, last calibration date, and

alarm limits. All data is retained (even after the unit is turned

off) in non-volatile memory so that it can be down loaded later

to a PC.

Datalogging event

Each time the monitor is turned on, or a configuration parameter

is changed, a new datalog event is created. Information, such as

start time, user ID, site ID, serial number, last calibration date,

3. OPERATION OF ACCESSORIES

The accessories for the UltraRAE include:

• Battery charger

• Alkaline battery adapter

• Dilution fitting

• Calibration adapter

3.1 Battery Charging Operation

The charging circuit of the UltraRAE is built into the monitor.

It only needs a regular AC to 12 V DC adapter (wall mount

transformer) to charge the monitor. Charging should be done

with the unit turned off.

1. Connect the AC adapter (or the optional automotive

charging adapter) to the DC jack on the UltraRAE monitor.

If the unit was off, it will automatically turn on.

2. The first message displayed will be “Deep discharge?” This

message will remain on the display for three seconds. If the

user wants to discharge the battery pack, affirm this query

with the [Y/+] key, otherwise the unit will abandon this

function and move on to the charge mode.

3. While charging, the display message will alternate between

“Charging” and “Bat=x.xV” (x.x is the present battery

voltage). The LED should be red in color when charging.

4. When the battery is fully charged, the LED will change

from red to green and the message “Fully charged” will

appear on the display. The red color indicates that the

battery is being charged. The green color indicates that the

battery is fully charged. After the battery is fully charged,

the unit will enter the “trickle charge” mode. In this mode,

OPERATION OF ACCESSORIES

3 - 2

the red LED will turn on for two or three seconds, every

minute, to maintain the full charge.

A completely discharged UltraRAE monitor will be charged to

full capacity within 10 hours.

Figure 3-1 Charging the Battery

The battery will be drained slowly even if the monitor is turned

off. If the monitor has not been charged for 5-7 days, the

battery voltage will be low.

The factory supplied battery is designed to last for 12 hours of

normal operation (no alarm, no back light condition), for a new

battery under the best condition. As the battery becomes older

or is subject to adverse conditions (such as cold ambient

temperature), the battery capacity will be reduced significantly.

It accepts four AA size alkaline batteries and can be used in

place of the Ni-MH or Ni-Cd battery pack to provide

approximately 12-14 hours of operation. The adapter is

intended for emergencies when there is no time to charge the

Ni-Cd or Ni-MH battery pack.

To install the adapter, remove the cover of the monitor.

Remove the Ni-Cd or Ni-MH battery pack from the battery

compartment and replace with the alkaline battery adapter.

Replace the battery compartment cover.

The internal charging circuit is designed to prevent damage to

alkaline batteries and the charging circuit when alkaline

batteries are installed inside the monitor.

Note: The AA Alkaline battery adapter supplied by

RAE Systems Inc. is intrinsically safe!

3.3 Dilution Fitting

The user may wish to install a dilution fitting in front of the

RAE-SEP tube to dilute the gas samples. One application for a

dilution fitting is to measure organic gas when the concentration

exceeds the upper limit of the sensor range.

Make sure to set the dilution ratio in the programming mode

(see Section 4.3) so that the correct gas reading will be

displayed when the dilution fitting is used.

WARNING: To use a dilution fitting, the user

must have the monitor located in a clean

atmosphere outside the confined space and use a

remote access probe or inert tubing to measure

the gas concentration inside the confined space.

4.4 Calibration of the UltraRAE Monitor

CALIBRATION WARNINGS:

The Calibration of all newly purchased RAE Systems

instruments should be tested by exposing the sensor(s) to

known concentration calibration gas before the instrument

put into service for the first time.

For maximum safety, the accuracy of the UltraRAE should

be checked by exposing the sensor(s) to known

concentration calibration gas before each day’s use.

In the programming mode, the user may re-calibrate the

UltraRAE monitor. This is a two-point calibration process

using “fresh air“ and a standard reference gas. First a “fresh

air” calibration, which contains no detectable VOC (0.0 ppm), is

used to set the zero point for the sensor. Then a standard

reference gas, which contains a known concentration of a given

gas, is used to set the second point of reference (also known as

span gas). Separate calibration must be performed for each type

of tube being used.

Note: The span value must be set prior to calibrating for fresh

air or span.

Calibration Sub-Menu

Fresh air calib?

Span calib?

Modify span value?

Calibration Frequency

To achieve the highest level of measurement accuracy, it is

recommended that the monitor be calibrated once a day before

PROGRAMMING

4 - 6

it is used. If this is not possible, then the monitor should be

calibrated at least once a week.

Correction Factors Not Possible

It is necessary to calibrate for each type of RAE-Sep tube

directly with the gas to be measured and with the corresponding

RAE-Sep tube in place. It is NOT possible to calibrate with a

surrogate gas (such as isobutylene) and then apply a correction

factor. This is because the surrogate gas is often absorbed on

the RAE-Sep tube, or elutes at a different rate than the desired

gas.

PROGRAMMING

4 - 7

4.4.1 Fresh Air Calibration

This procedure determines the zero point of the sensor

calibration curve. To perform fresh air calibration, the

calibration adapter, a bottle of “fresh” air, and a Tedlar bag

(optional), or a charcoal filter are required. The “fresh” air is

clean dry air without any organic impurities. If such an air

bottle is not available, any clean ambient air without detectable

contaminant or a charcoal filter can be used.

The calibration adapter links the inlet port of the UltraRAE

monitor to the Tedlar bag or the charcoal filter. First fill the

Tedlar bag with “fresh” air from the bottle before starting.

1. The first sub-menu shows: “Fresh air calib?”

2. Insert a new, unused, RAE-SEP tube into the monitor and

secure the cap. If a “fresh” air bottle is available, fill the

Tedlar bag with the “fresh” air. Next, snap the calibration

adapter over the inlet port of the UltraRAE monitor and

connect the other end of the tube to the Tedlar bag. If a

charcoal filter is used, connect the filter to the inlet port of

the UltraRAE monitor. If the “fresh” air bottle or charcoal

filter is not available, make sure the monitor is in an area

free of any detectable vapor.

3. Press the [Y/+] key. The monitor will identify the inserted

tube and display the tube name. If the tube cannot be

identified, the tube can be manually selected by responding

with [N/-] until the correct tube name is displayed.

4. Press the [Y/+] key when the correct tube name is displayed

to start “fresh air calibration” of the monitor. The display

shows “zero in progress” followed by “wait..” and a

countdown timer.

5. When the sampling is complete, the display will show the

message “zeroed… reading = 0.0 … done!” The next sub-

menu will be displayed (“Span calib?”).

Note: The charcoal filter has a check box so that user can mark

off a box each time the filter has been used. The charcoal filter

should be replaced after four calibrations.

PROGRAMMING

4 - 8

4.4.2 Span Calibration

This procedure is the second type of sensor calibration. A

bottle of standard reference gas (span gas) and a Tedlar bag are

needed to perform this procedure. First, fill the Tedlar bag with

the span gas. Connect the calibration adapter to the inlet port of

the UltraRAE Monitor, and connect the tube to the Tedlar bag.

Before executing a span calibration, make sure the span value

has been set correctly (see next sub-menu).

1. Advance to the next calibration phase (Span calib), the

display should show “Span calib?

2. Insert a new RAE-SEP tube into the monitor. (Note: For

VOC calibration, there is no need to use a new VOC tube).

First fill the Tedlar bag (Do not overfill with span gas).

Then connect the bag to the inlet port.

3. Press the [Y/+] key. The monitor will identify the inserted

tube and display the tube name. If the tube cannot be

identified, the tube can be manually selected by responding

with [N/-] until the correct tube name is displayed.

4. Press the [Y/+] key when the correct gas name is shown.

The display shows “Span gas = xx ppm?” If incorrect, press

the [N/-] key and correct the span gas value. When the span

gas value is correct, open the valve to the Tedlar bag and

press the [Y/+] key to start the calibration. The display

reminds the user to “Apply gas now!” and begins a

countdown timer showing the number of remaining seconds.

When the count down timer reaches zero, the display shows

the calibrated value. Turn off the gas and press [MODE]

key to exit calibration

5. This completes the calibration procedure for a gas. The

display shows the next calibration sub-menu.

When the barcode reader is “On”, the UltraRAE reads the barcode

when a tube is inserted. The unit automatically identifies the tube

type and applies the calibration and measurement time for the

tube identified. This condition is most convenient for users who

switch frequently between tube types. When the barcode reader is

“On” it may occasionally need adjustment to identify the tubes

properly (see Section 8.1 Paragraph 8 on CCD Reader).

When the barcode reader is “Off”, the user must be sure to

identify the tube type properly before starting measurements.

Thereafter, the monitor will assume the same tube type even if

no tube is in place. It is important to select the tube type

correctly because this determines the lamp required and the

measure wait time.

!! CAUTION !!

If the incorrect tube type is programmed or the Measure Wait

Time is otherwise set too short, it is possible to underestimate

the VOC concentration and thereby cause overexposure.

The “measure wait time” is the time, in seconds, between the

start of a sample and the time the unit completes and datalogs a

measurement. The unit is preprogrammed to wait the optimum

amount of time, based on the type of tube being used. Each

tube type can be programmed separately. The user may want to

adjust this time in special situations. For example, when using

longer tubing to collect a remote sample (see Technical Note

140), longer times at low temperatures and shorter times at high

temperatures (see tube Data Sheets). Care must be taken when

setting this parameter because the final measurement value

depends on it. The minimum time is 10 seconds (time for UV

lamp to stabilize), and the maximum time is 255 seconds (4.25

minutes). For VOC tube measurements, this time is used only

during calibration; during normal VOC measurements the

readings run continuously until the user manually ends the

measurement.

THEORY OF OPERATION

6 - 1

6. THEORY OF OPERATION

The UltraRAE monitor uses a newly developed electrodeless

discharge UV lamp as the high-energy photon source for the

PID. As organic vapors pass by the lamp, they are photo-

ionized and the ejected electrons are detected as a current. The

PID sensor will detect a broad range of organic vapors. A lamp

with high photon energy (e.g. 11.7 eV) will measure the most

kinds of compounds, whereas low photon energies (e.g. 9.8 eV)

are selective for easily ionizable compounds such as aromatics.

The gas separation tube filters out unwanted gases and allows

the target gas to be measured.

The RAE-SEP benzene tube uses a combination of adsorption

and oxidation to remove most common organic compounds

other than benzene. Methane, ethane, propane, and some

butane passes through the tube but is not detected by the PID.

THEORY OF OPERATION

6 - 2

The PID sensor for this UltraRAE monitor is constructed as a

small cavity in front of the UV lamp. A diaphragm pump is

installed inside the monitor enclosure to draw air sample into

the sensor through the gas separation tube and then exits

through the gas outlet port on the side of the enclosure.

A single chip microcomputer is used to control the operation of

the alarm buzzer, LED, pump and light sensor. It measures the

sensor readings and calculates the gas concentrations based on

calibration to known standard gases. The data is stored in non-

volatile memory so that it can be sent to a PC for record

keeping. RS-232 transceivers provide a serial interface between

the monitor and the serial port of a PC. An LCD display

consisting of a single row of eight alpha/numeric characters is

used to display the readings. The user interacts with the

monitor through three keys on the front panel keypad.

The monitor is powered by a rechargeable NiMH, NiCd battery,

or an alkaline pack.

NOTE: The printed circuit board of the monitor is

connected to the battery pack even if the power is

turned off. Therefore, it is very important to

disconnect the battery pack before servicing or

replacing any components inside the monitor.

Severe damage to the printed circuit board may

occur if the battery pack is not disconnected before

servicing the unit.

7.1 Battery Replacement

When the display shows a flashing message “Bat”, the battery

requires recharging. The battery may be replaced in the field

(in area known to be non-hazardous) if required. It is

recommended to recharge the UltraRAE monitor upon returning

from fieldwork. A fully charged battery powers an UltraRAE

monitor for 12 hours continuous operation. The charging time

is less than 10 hours for a fully discharged battery. The built-in

charging circuit is controlled by two-step constant

voltage/constant current charging to prevent over-charging.

7.3 Sampling Pump

The sampling pump is positive displacement piston pump.

When approaching the end of the specified lifetime of the

pump, it will consume higher amount of energy and reduce its

sample draw capability significantly. When this occurs, it is

necessary to replace or rebuild the pump.

To check the pump flow, remove the tube holder and insert a

piece of 3/16” (4 mm) glass or metal tubing into the rubber tube

connector in the sensor module (see Figure 7-4). The flow

should be above 350 cc/min. The flow with a RAE-SEP

benzene tube in the normal configuration should be greater than

200 cc/min.

8. TROUBLESHOOTING

To aid the user in diagnosing the monitor, the monitor has a

special diagnostic mode that can display critical, low level

parameters. Section 8.1 describes the operation of the

diagnostic mode. Section 8.2 summarizes the frequently

encountered problems and suggested solutions. Turning on the

UltraRAE monitor in diagnostic mode and using the

troubleshooting table in Section 8.2, the user can usually narrow

the problem down to one or two areas and correct the problem

without having to return the monitor for repair.

WARNING: The diagnostic mode allows the user to set

several low-level parameters that are very critical to the

operation of the monitor. Extra care should be taken when

setting these low-level parameters. If the user is not familiar

with these parameters and sets them incorrectly, it may

cause the monitor to shut down or malfunction.

The following is a brief description of a few diagnostic

displays:

1) Raw Sensor Readings

The raw sensor readings provide a quick diagnosis on the

response and the sensitivity of the sensor. When zero gas (fresh

clean air) is applied to the monitor, the raw sensor readings

typically should be between 100 and 300. If the raw reading is

outside this range when zero gas is applied, the sensor or the

electronics may be defective. Channel A is the PID sensor.

Channel B is an auxillary channel that is not used.

When a specific gas is applied to the monitor, the raw reading

should increase. If the reading does not change when the

specific gas is applied, then the sensor or lamp may be

defective.

2) Adjust Lamp Failure Threshold

This display can be used to calibrate the PID lamp failure

threshold. If the lamp appears to be good but in normal

operation, a lamp failure message (i.e. “Lamp”) is displayed, the

lamp failure level may be set too high. This level can be

adjusted by using the following steps:

1. Turn the monitor off. Remove the UV lamp from the PID

sensor (see Section 7.2)

2. Turn the monitor on in the special diagnostic mode ([Y/+] +

[MODE]).

3. Press the [MODE] key until “Lamp xxx” is displayed, write

done this number. The reading “xxx” is the lamp current

reading.

4. Press the [MODE] key one more time. Fail yyy ” is now

displayed. The value “yyy” is the threshold level that

determines a lamp failure. Anything below this level is

considered a failure.

5. Push the [Y/+] or [N/-] key to increase or decrease the

threshold value “yyy” until it is about 10 - 15 counts above

the “xxx” value. This will optimally set the lamp failure

threshold. Press [MODE] key to exit this display. If the

threshold value has changed, a message “Save?” will

appear. Press [Y/+] to confirm the change, [N/-] or

[MODE] key to abandon the changes.

6. Turn the monitor off and replace the lamp.

7. To verify the above adjustment, turn the monitor back on in

diagnostic mode and press the [MODE] key until “Lamp

xxx, press the [MODE] key once more, Fail yyy +/-” is

display. The lamp current reading “xxx” should be higher

than the threshold value “yyy” by at least 10-15 counts. If

not, the lamp may be defective or very weak.

In most cases, lamp failure threshold adjustment is not required,

in which case the user should press [MODE] key to exit this

display.

3) Battery Type

The UltraRAE monitor can be powered by either a rechargeable

NiMH / Ni-Cd battery pack or an alkaline battery adapter. This

display shows the type of battery that is currently installed in

the monitor. The charger cable must be unplugged for a correct

battery type display.

4) Adjust LCD Contrast

This display allows the user to adjust the LCD contrast. Press

[Y/+] to increase the contrast and [N/-] key to decrease the

contrast. The bar graph shows the current LCD contrast setting.

If the display appears blank or very faint, press the [Y/+] key

several times to increase the contrast or darken the display.

5) DAC Output Counts

The menu allows the user to adjust the value of the analog

output DAC use the [Y/+] and [N/-] keys. The remote alarm

output signal on the serial interface cable is deselected and the

analog output signal is selected in its place. This signal has a

range of 0 to 2.5V in 4096 steps. The initial default output is

2048, or half-scale. See Figure 8-1 for signal pin-out. The

DAC output is linearly proportional to concentration.

6) Alarm Test

This menu is used to test the monitor’s alarm generators,

including four bright LED’s, the loud buzzer, and the vibrator

output signal (remote alarm). The message “Alarm” is first

displayed, followed by “On?” If the [Y/+] key is pressed at this

point, the alarms will turn on and the message “Off?” will

appear. To turn the alarms off, press the [Y/+] key again.

Check external alarm signal at connector.

7) Adjust Backlight Threshold

This display can be used to calibrate the LCD backlight turn on

and off threshold. Use the following steps to adjust the

backlight threshold.

1. The “Lite = xxx” message displays the present ambient light

level incident on the face of the monitor. In a brightly lit

room, the light reading should be above 130.

2. The user can shade the light sensor, which is located at the

upper left corner of the monitor, with their hand and watch

the light sensor reading. The light reading should drop to

less than 100. Determine the ambient light level when the

back light should be turned on and record the light sensor

reading. Press the [MODE] key one more time, the display

should show the message “Trip= yyy”.

3. Use [Y/+] or [N/-] key to increase or decrease the trip value

until it is about the same as the previously recorded light

sensor reading. Press [MODE] key to exit this display. If

the threshold value is changed, a message “Save?” will

appear. Press [Y/+] to confirm the change, [N/-] or [MODE]

key to abandon the changes.

8) CCD Tube Reader

This function displays the total number of light sensing

elements that are exposed to light (IR). The maximum value is

64 with no tube inserted. If this number is less than 64 when no

tube is present, increase the light collecting ability of the CCD

by pressing the [Y/+] key until this number just reaches 64.

Then press the [Y/+] key two more times.

With a Benzene RAE-SEP tube inserted, this number should be

46 to 52. For the VOC tube, this number should be 59 to 61.

Use the [Y/+] or [N/-] key to increase or decrease this count

until it is within range.

9) Battery Deep Discharge

This function allows the user to fully discharge the NiCd /

NiMH rechargeable batteries. If the monitor is repeatedly used

for only a few hours and then charged, or if the monitor’s

useable run time has decreased significantly, a deep discharge

cycle may restore some of the battery’s capacity. Before

starting this function, the AC adapter should be plugged in.

Press the [Y/+] key to confirm the start of this function.
