3.1.2. LCD Flip

The QRAE 3 senses its vertical/horizontal orientation, and can automatically flip the display180

degrees, making it easy to read if the QRAE 3 is upside down. (You can turn this feature on or off

in Programming Mode, under “Monitor.”) As the QRAE 3 is tilted, the sensor detects its

orientation and inverts the screen when it passes its horizontal position.

3.1.3. Keys & Interface

The QRAE 3 has two keys:

MODE

Y/+

In addition to their labeled functions, the keys labeled [MODE] and [Y/+] act as “soft keys” that

control different parameters and make different selections within the instrument’s menus. From

menu to menu, each key controls a different parameter or makes a different selection.

Two panes along the bottom of the display are “mapped” to the keys. These change as menus

change, but at all times the left pane corresponds to the [MODE] key, and the right pane

corresponds to the [Y/+] key. Here are examples that show the relationships of the keys and

functions:

In addition to the functions described above, either key can be used to manually activate display

backlighting. Press a key when the backlighting is off to turn it on.

QRAE 3 User’s Guide

3.2. Screen Display For Various Numbers Of Active Sensors

The QRAE 3 family of instruments can accommodate from one to four sensors. In order to

maximize readability and the amount of information shown, the display is automatically

reconfigured, according to the number and types of sensors in the QRAE 3.

One se nsor.

Two sensors.

Three sensors.

Four sensors.

3.3. Menus

The reading menus are easy to step through by pressing the [MODE] and [Y/+] key.

4. Wireless Control And Submenus

Note: These are only present if the QRAE 3 is equipped with a wireless module.

QRAE 3 User’s Guide

5. Battery

Always fully charge the battery before using the QRAE 3. Its Li-ion battery is charged by placing

the QRAE 3 in its Travel Charger. Contacts on the bottom of the instrument meet the Travel

Charger’s contact pins, transferring power.

Battery pack (P/N G02-3004-000) is used for QRAE 3.

Note: Before attaching the QRAE 3 to its Travel Charger, visually inspect the contacts to make

sure they are clean. If they are not, wipe them with a soft, dry cloth. Do not use solvents or

cleaners.

WARNING

To reduce the risk of ignition of hazardous atmospheres, recharge, remove or replace the

battery only in an area known to be non-hazardous! Do not mix old and new batteries or

batteries from different manufacturers.

Next, put the plug from the power supply into the jack on the side of the Travel Charger.

Note: For ATEX/IECEx applications, plug the cord from the Barrier Box (P/N M02-3011-000)

into the Travel Charger, and then plug the power adapter into the Barrier Box.

Non-ATEX/IECEx: Power supply plugged

The battery icon on the display shows how much charge is in the battery and alerts you to any

charging problems.

Full charge

2/3 charge

1/3 charge

Low charge

Battery alert

When the battery’s charge falls below a preset voltage, the instrument warns you by beeping

once and flashing once every minute, and the “empty battery” icon blinks on and off once per

second. The instrument automatically powers down within 10 minutes, after which you will

need to either recharge the battery, or replace it with a fully charged one.

QRAE 3 User’s Guide

6. Turning The QRAE 3 On And Off

6.1. Turning The QRAE 3 On

With the instrument turned off, press and hold the [MODE] key until the audible alarm stops, and then

release.

When starting up, the QRAE 3 turns the backlight on and off, beeps once, blinks once, and

vibrates once. A RAE Systems logo should appear first. During a normal startup, this is followed

by a progression of screens that tell you the QRAE 3’s current settings:

• Product name and model number, air flow type, and serial number

• Application firmware version, build date, and build time

• Installed sensors (including production/expiration/calibration date and alarm limit settings)

• Current date, time, and temperature

• User mode and operation mode

• Battery type, voltage, shutoff voltage

• Alarm mode and alarm settings

• Datalog period (if it is activated) and interval

• Policy Enforcement settings

Then the QRAE 3’s main reading screen appears. It takes 1 to 2 minutes for sensors to show a reading, so if

any have not warmed up by the time the main screen is shown, you will see “- -” instead of a numerical

value until the sensor provides data (typically less than 2 minutes). Then it displays instantaneous readings

similar to the following screen (depending on the sensors installed) and is ready for use.

Note: If the battery is completely empty, then the display briefly shows the message “Battery Fully

Discharged,” and the QRAE 3 shuts off. You should charge the battery or replace it with a fully charged

battery before turning it on again.

IMPORTANT!

If a major error that prevents the QRAE 3 from functioning is found during startup, the message “Please

Contact Service Department” is shown on the display. The instrument should be shut off and serviced.

6.2. Turning The QRAE 3 Off

Press and hold [MODE]. A 5-second countdown to shutoff begins. You must hold your finger on

the key for the entire shutoff process until the QRAE 3 is powered off.

Caution: The alarm is very loud. During startup, you can mute most of the sound by holding a

finger over the alarm port. Do not put tape over the alarm port to permanently mute it.

QRAE 3 User’s Guide

6.3. Testing Alarm Indicators

Under normal-operation mode and non-alarm conditions, the buzzer, vibration alarm, LED, and

backlight can be tested at any time by pressing [Y/+] once.

IMPORTANT!

If any of the alarms do not respond to this test, check the Alarm Settings in Programming Mode.

It is possible that any or all of the alarms have been turned off. If all of the alarms are turned on,

but one or more of them (buzzer, LED lights, or vibration alarm) does not respond to this test, do

not use the instrument. Contact your RAE Systems distributor for technical support.

6.4. Pump Status IMPORTANT!

During operation, make sure the probe inlet and the gas outlet are free of obstructions.

Obstructions can cause premature wear on the pump, false readings, or pump stalling. During

normal operation, the pump icon alternately shows inflow and outflow as shown here:

If there is a pump failure or obstruction that disrupts the pump, the alarm sounds and you see this

icon blinking on and off:

Once the obstruction is removed, you can restart the pump by pressing the [Y/+] key. If the pump

does not restart, and the pump stall alarm continues, consult the Troubleshooting section of this

guide or contact your RAE Systems distributor for technical support.

Note: Pump Status is not indicated on the diffusion QRAE 3.

6.5. Calibration Status

If one or more sensors requires calibration, then the screen displays the word “Alarm” at the top

and alternates between the sensor reading and the word “Cal” with a highlighted background:

Calibration is required if:

• The sensor module has been replaced with one whose calibration is overdue.

• The defined period of time between calibrations has been exceeded. (See Section 9 for

information on policy enforcement.)

• If you have changed the calibration gas type without recalibrating the instrument.

• The sensor has failed a previous calibration.

QRAE 3 User’s Guide

6.6. Bump Status

If one or more sensors requires a bump test, then the screen displays the word “Alarm” at the top

and alternates between the sensor reading and the word “Bump” with a highlighted background:

A bump test is required if the defined period of time between bump tests has been exceeded. This

interval is set by an administrator using ProRAE Studio II.

7. Modes Of Operation

The QRAE 3 has two user modes.

7.1. Basic User Mode

In Basic User Mode, some restrictions are applied, including password protection that guards

against entering Programming Mode by unauthorized personnel.

7.2. Advanced User Mode

In Advanced User Mode, there are no access restrictions (you do not need a password), and the

QRAE 3 provides the indications and data you need most for typical monitoring applications.

8.3.1. Editing And Selecting Parameters And Sensors

There are a few basic ways to edit parameters, select sensors, and perform other activities

in the QRAE 3. The actions performed by pressing keys always match 1-to-1 with the

boxes along the bottom of the display and the two keys. Some parameters are edited by

scrolling and selecting individual items (black bars behind white text act as highlighters).

Some include a choice via “radio keys,” where only one item in a list can be selected,

while other menus use boxes for you to “check” with an “X,” and these allow for

multiple items in a list to be selected. In all cases of editing, you can save or undo your

choice.

QRAE 3 User’s Guide

8.3.2. Calibration

Use this menu to perform zero or span calibration for one or more sensors, and change the gas

concentration value assumed to be used in span calibration, as well as zero calibration and calibration

reference gas.

8.3.2.1. Multi Bump

Depending on the configuration of your QRAE 3 and the span gas you have, you can perform a

bump test simultaneously on multiple sensors.

The selected sensors and their values are shown on the screen. With calibration gas connected to

the instrument, start a multiple bump test by pressing [Y/+]. If you do not want to perform a

multiple bump test, press [MODE].

Note: You can abort a multiple bump test by pressing [MODE] once testing has started.

When the Multi Bump test is done, a screen is shown, with the sensor names and either “Pass” or

“Fail” shown next to them.

8.3.2.2. Multi Zero

You can perform a zero calibration simultaneously on multiple sensors. This procedure

determines the zero point of the sensor calibration curve for all the sensors that require a zero

calibration. The instrument should be zero calibrated in clean ambient air with 20.9% oxygen. A

zero calibration should precede a span calibration.

The QRAE 3 has extensive onboard gas libraries for combustible gases that you can use to

configure your instrument to automatically apply the appropriate correction factors and produce

readings in the units of the desired combustible gas.

LEL measurement gases are organized in two lists:

• Custom Gases are gases with user-modified parameters. Using ProRAE Studio II, all

parameters defining a gas can be modified, including the name, span value(s), correction

factor, and default alarm limits.

• Gas Library is a library that consists of many of the gases found in RAE Systems’ Technical

Note TN-156 (available online at www.raesystems.com). Methane is the default gas.

(combinations of light, buzzer, and vibration alarm indications).

8.3.3.5. Alarm Limits

There are four groups of alarm settings that you can adjust for each individual sensor for which a

particular alarm type is available.

Settings:

• High Alarm

• Low Alarm

• STEL Alarm

• TWA Alarm

Note: Some alarm settings are not applicable to all sensors. If a setting is irrelevant to a sensor (in

some cases STEL or TWA are not relevant to a sensor), then that sensor does not appear in the

list for alarm limits.

QRAE 3 User’s Guide

8.3.3.6. Alarm Mode

You can program the QRAE 3 so that there are two ways to shut off an alarm:

Auto Reset

When the alarm condition is no longer present, the alarm stops and resets itself.

Latch

The latched setting only controls alarms for High Alarm, Low Alarm, STEL

Alarm, and TWA alarm. When an alarm is in “latched” mode, the alarm signal

remains on even when the alarm condition is no longer present Press [Y/+] to

acknowledge and reset alarm signals.

8.3.3.7. Alarm Settings

You can enable/disable any combination of light (LEDs), buzzer, and vibration alarms.

Settings:

• All Enabled

• Light

• Vibration

• Buzzer

• Buzzer & Light

• Buzzer & Vibration

• Vibration & Light

• All Disabled

8.3.3.8. Comfort Beep

A Comfort Beep is a single beep of the audible alarm at 60-second intervals that reminds the

person using the QRAE 3 that it is functioning. It can be turned on or off.

8.3.3.9. Man Down Alarm

The Man Down Alarm is a critical and potentially lifesaving safety feature of every QRAE 3. The

Man Down Alarm is based on the premise that if the instrument is motionless when it is not

supposed to be, something wrong may be happening to its user. If that is the case, the QRAE 3

not only goes into alarm locally on the instrument, but also remotely, over the RAE Systems

Dedicated Wireless Network, to notify people in the vicinity, as well as remote safety officers at a

command center, that a person is down, so that help can be dispatched quickly.

Note: Remote notification requires wireless connection to a network.

Whenever the Man Down feature is on, the main screen displays a Man Down icon along the top to

indicate it is active:

QRAE 3 User’s Guide

When the Man Down feature is on and there is no gas alarm, the QRAE 3 senses that it is motionless for the

amount of time set in the “Motionless Time” parameter. If the instrument is not moved during that time, then

a pre-alarm is activated to alert the user, and shows the “Are You OK?” screen. Pressing [Y/+] clears the

alarm and returns the QRAE 3 to its normal operation. Pressing [MODE] sets it into Man Down Alarm (and

if wireless connectivity is enabled, a Man Down message is sent in real time to remote observers). If neither

key is pressed, then after the countdown, it goes into Man Down Alarm (again sending a message to remote

observers if wirelessly enabled).

Settings are available for:

• Off/On

• Motionless Time (time the instrument is motionless before initiating a pre-alarm)

• Sensitivity (set to low, medium, or high to compensate for ambient vibration or motion)

• Warning Time (countdown, in seconds, from pre-alarm to Man Down alarm)

When the Man Down alarm is activated, the buzzer sounds and LEDs flash continuously, and a countdown

begins.

• If the QRAE 3’s user presses [Y/+] for “Yes” in response to the “Are You OK?” question on

the screen before the countdown reaches zero, the Man Down alarm stops and the main reading

screen is displayed.

• If the person does not press [Y/+] for “Yes” in response to the “Are You OK?” question on the

screen before the countdown reaches zero, the Man Down alarm is sounded and LEDs flash

continuously.

• If the person presses [MODE] during the countdown, answering the “Are You OK?” question

with “No,” the Man Down alarm starts.

If wireless connectivity is enabled, and the QRAE 3 is connected to a network, a Man Down message is

also sent to remote observers.

8.3.4. Datalog

The instrument displays a floppy disk icon to indicate that a datalog is being recorded. The

instrument stores the measured gas concentration for each sensor, date and time for each

measurement, Site ID, User ID, and other parameters. The QRAE 3 memory is sufficient to

record three months’ worth of data for four sensors at one-minute intervals. All data are retained

(even after the unit is turned off) in non-volatile memory so that they can be downloaded at a later

time to a PC.

8.3.4.1. Clear Datalog

This operation erases all data stored in the datalog.

Note: Once the datalog is cleared, the data cannot be recovered.

QRAE 3 User’s Guide

8.3.4.2. Interval

Intervals are shown in seconds. The default value is 60 seconds. The maximum interval is 3600

seconds, and the minimum is 1 second.

8.3.4.3. Sensor Selection

You can choose which sensors’ data are included in the datalog. The entire list of installed

sensors is shown, and you can individually select whether their data is included.

Note: Turning a sensor off in the list does not change or erase its settings.

8.3.4.4. Data Selection

Data Selection allows you to select which types of data are stored and made available when you

download your datalog to a computer via ProRAE Studio II (version 1.7.0 or higher) software.

You can choose any or all of four types of data (you must choose at least one):

• Minimum

• Average

• Maximum

• Real Time

8.3.4.5. Datalog Type

The instrument offers two options for starting the datalogging process:

Auto Automatically collects datalog information every time the instrument is sampling

until the datalog memory is full.

Manual Datalogging occurs only when you manually initiate it (see below for details).

Note: You can only choose one datalog type to be active at a time.

About Manual Datalog

When the instrument is set to Manual Datalog, you can turn datalogging on and off by repeatedly

pressing [MODE] and stepping through the screens from the main display until you reach the

screen that says “Start Datalog?”

• When you reach the screen that says “Start Datalog?” press [Y/+] to start it. You see

“Datalog Started,” confirming that datalogging is now on.

• If datalogging is running, it says, “Stop Datalog?” Press [Y/+] to stop datalogging.

Otherwise, press [MODE] to advance to the next screen.

8.3.4.6. Action When Full

When the internal datalog memory is full, the QRAE 3 can either stop collecting data (Stop when

full) or go back to the beginning and overwrite the data from the first entry, second entry, etc.

(Wraparound).

8.3.5. Monitor

The display’s backlight can be set to illuminate either automatically, based on ambient light

conditions, or manually, or it can be shut off.

8.3.5.3. Pump Speed

If the QRAE 3 is equipped with a pump, the pump can operate at two speeds, high and low.

Running at low speed is quieter, extends pump lifespan, and conserves a small amount of power.

There is almost no difference in sampling accuracy. Note: High speed should be used for exotic

sensors and for taking samples via a hose from a long distance.

8.3.5.4. Site ID

Choose and enter an 8-digit Site ID to uniquely identify the particular site where the instrument is

to be used. The first four digits can be an alphabet letter or number, while the last four digits can

9. Policy Enforcement

The QRAE 3 can be configured to enforce a facility/company’s requirements that

calibration and/or bump testing be performed at specified intervals, and to warn the user

that calibration/bump testing is required. In addition, it can require calibration or bump

testing and not allow normal operation of the instrument unless calibration or bump

testing is performed.

If Policy Enforcement is enabled and if the instrument has been bump tested and

calibrated in compliance with the policy settings, a check-mark icon is included along the

top of the QRAE screen:

If Policy Enforcement is enabled, then after startup the QRAE 3 displays a screen that

informs the user that the instrument requires either a bump test or a calibration. If both

are required, then they are shown in sequence.

10. Calibration And Testing

10.1. Manual Alarms Test

Under Normal Operation Mode and non-alarm conditions, the buzzer (audible alarm),

vibration, visible alarms, and backlight can all be tested anytime by pressing [Y/+]. If any

alarm does not respond, check the alarm settings in the Programming Menu to make sure

all alarms are enabled (selected setting under Programming/Alarms/Alarm Settings

should be “All Enabled”). If any alarms are enabled but not functional, the instrument

should not be used.

10.2. Bump Testing And Calibration

RAE Systems recommends that a bump test be conducted periodically on the QRAE 3. The

purpose of a bump test is to ensure that the instrument’s sensors respond to gas and all the alarms

are enabled and functional.

• The QRAE 3 multi-gas detector must be calibrated if it does not pass a bump test, or at

least once every 180 days, depending on use and sensor exposure to poisons and

contaminants.

• Calibration intervals and bump test procedures may vary due to national legislation.

A bump test can be performed either manually or using the AutoRAE 2 Automatic Test and

Calibration System. When a bump test is done manually, the instrument makes a pass/fail

decision based on sensor performance, but the user still has the responsibility to make sure all the

alarms are enabled and functional.

Note: Bump testing and calibration can be performed using an AutoRAE 2 Automatic Test &

Calibration System. An AutoRAE 2 bump test takes care of both the sensor and alarm tests.

Consult the AutoRAE 2 User’s guide for details.

QRAE 3 User’s Guide

10.2.1. Bump (Functional) Testing

The same gas is used for a bump test as for calibration. A constant-flow regulator producing 0.5

to 1 liters per minute should be used, and the calibration adapter must be installed on diffusion

models. The instrument must be connected to a cylinder of calibration gas with supplied tubing.

Note: Pumped models require a T calibration tube, as illustrated below.

1. Turn on your QRAE 3 by pressing and holding the [MODE] key, and allow the

instrument to boot up fully until the main measurement screen with sensor names and

readings is shown.

Important! Make sure all of the instrument’s sensors have warmed up before performing the

bump test. The instrument will take the time to warm up the sensors prior to enabling access

to bump test menus. You can tell a sensor has warmed up if you see a reading next to it name

on the display. If it has not warmed up, you see three dashes (“--”) next to it.

2. Install the calibration adapter on the QRAE 3 if it is a diffusion model.

3. Turn on the gas to initiate flow.

4. Connect the instrument to the T calibration tube and connect it to the calibration gas.

5. Press Start ([Y/+] key) to start the bump test, or press [MODE] to quit. While the bump

test is being performed, the readings for each sensor are shown. Once the bump test

completes, pass/fail test results and readings are shown for each sensor.

Important! If one or more sensors fails a bump test, be sure to calibrate those sensors.

6. The bump test is now complete. Press [Y/+] to exit and return to the Calibration menu.

If all the alarms and all sensors have passed and no sensor is due for a calibration, the

instrument is now ready for use.

Note: Make sure pressure in

the calibration gas cylinder

is higher than 100 psi when

using a T calibration tube

(pumped models only).

Diffusion models

require calibration

cap, but no T

calibration tube.

QRAE 3 User’s Guide

10.3. Zero Calibration

This operation sets the zero point of the sensor calibration curve for clean air. It should be

performed before other calibrations.

Note: If you use a zero air cylinder, you must use the QRAE 3 Calibration Adapter (and a T

calibration tube if the instrument has a pump). Using a calibration adapter is not necessary for

calibration in fresh air.

10.3.1. Zero Calibration

This procedure determines zero points of most sensors. The QRAE 3 should be zero-calibrated in

clean air with 20.9% oxygen or with a cylinder of clean zero air.

At the Calibration menu, select “Fresh Air” by pressing [Y/+] once to enter fresh air calibration.

After a timer countdown, the zero calibration is done. The LCD displays the sensor names and

tells you whether each calibration passed or failed, followed by the sensor readings.

The QRAE 3 pump draws at a flow rate of between 200cc/min and 450cc/min. The

instrument must be connected to a cylinder of calibration gas with supplied tubing

featuring a T calibratio n tube (P/N M02-3008-000), as illustrated below.

Note: A constant-flow regulator with flow rates from 500cc/min to 1000cc/min should be used.

Note: Make sure pressure in

the calibration gas cylinder

is higher than 100 psi when

using a T calibration tube.

QRAE 3 User’s Guide

10.4.2. QRAE 3 Diffusion Model

Because there is no single inlet on the diffusion (non-pumped) version of the QRAE 3, a

Calibration Adapter (calibration cap for diffusion models: P/N M02-3009-000; calibration tube

for diffusion models: P/N M03-3010-000) is used for supplying calibration gas to all sensors at

one time. Follow these steps for attaching the Calibration Adapter:

1. Align the Calibration Adapter’s main body with the indented area around the QRAE 3’s

gas inlets.

2. Turn the knob clockwise to secure the Calibration Adapter to the instrument.

3. Connect the hose to the Calibration Adapter and to its gas source.

4. Make sure the Calibration Adapter is securely attached before starting the flow of

calibration gas. (The Calibration Adapter has small grooves on its underside to allow gas to

escape after passing over the sensors.)

13. Alarms Overview

The QRAE 3 provides an unmistakable five-way alarm notification system that combines local

alarms on the device with real-time remote wireless alarm notification to take worker safety to the

next level. Local alarms include audible buzzer alarm, visible alarm via bright LED lights,

vibration alarm, and an alarm notification on the display. These can be programmed or selectively

turned on or off.

13.1. Alarm Signals

During each measurement period, the gas concentration is compared with the programmed alarm

limits for Low, High, TWA and STEL alarm. If the concentration exceeds any of the preset

limits, the alarms are activated immediately to warn both the QRAE 3 user and a remote safety

officer (if wireless is enabled) of the alarm condition.

In addition, the QRAE 3 alarms if one of the following conditions occurs: battery voltage low,

pump blocked, etc.

When the low battery alarm occurs, there may be approximately 10 minutes of operating time

remaining. In this case, it is recommended that you promptly change or charge the battery in a non-

hazardous location.

QRAE 3 User’s Guide

13.2. Changing The Alarm Mode

Your choices are Auto Reset and Latched. A latched alarm stays on until you acknowledge the

alarm by pressing a key. An auto-reset alarm turns off when the condition that set off the alarm is

no longer present (for instance, a high H2S reading that exceeds the preset threshold and triggers

an alarm, but then lowers below that threshold, turning the alarm off).

1. Enter the Alarm Mode sub-menu of the Alarms section under the Programming Menu.

2. Select Auto Reset or Latched by pressing [MODE] to select, and [Y/+] to confirm the

choice.
