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

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.
14
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.

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.

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:
24
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.
25
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
Manual
Automatically collects datalog information every time the instrument is sampling
until the datalog memory is full.
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

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

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:

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.

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.
Diffusion models
require calibration
cap, but no T
calibration tube.
Note: Pumped models require a T calibration tube, as illustrated below.
Note: Make sure pressure in
the calibration gas cylinder
is higher than 100 psi when
using a T calibration tube
(pumped models only).
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.
3.
4.
5.
Install the calibration adapter on the QRAE 3 if it is a diffusion model.
Turn on the gas to initiate flow.
Connect the instrument to the T calibration tube and connect it to the calibration gas.
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.

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.
Note: You can abort the calibration at any time during the countdown by pressing [MODE].
10.3.2. Single-Sensor Zero Calibration
Select the sensor and then start the calibration by pressing [Y/+]. You can abort the procedure
anytime by pressing [MODE].
10.4.
Span Calibration
This procedure determines the second point of the sensor calibration curve for the sensor.
Note: When a manual calibration is performed, the readings shown are in the equivalent
units of the calibration gas, and not the measurement gas.
10.4.1. QRAE 3 Pumped Model
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 calibration 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.
36
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:
Calibration
Adapter
Hose to
Calibration
Gas Source
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.)
37
QRAE 3 User’s Guide
10.4.3 Multi-Sensor Span Calibration
This lets you perform a span calibration on multiple sensors simultaneously. It requires using the
appropriate span gas and that the concentration labeled on the gas cylinder matches the
concentration programmed in the QRAE 3.
1. Start the flow of calibration gas.
2. Attach the calibration adapter and gas to the QRAE 3.
3. Press [Y/+] to begin calibration. A countdown screen is shown. You can abort the
calibration at any time during the countdown by pressing [MODE].
If the calibration reaches its conclusion, it shows the sensor names and tells you whether the
calibration passed or failed, followed by the sensor readings.
10.4.4. Single-Sensor Span Calibration
To perform span calibration of an individual sensor, follow these steps:
1.
2.
3.
4.
5.
At the Calibration Menu, select “Single Sensor Span.”
Select a sensor from the list.
Start the flow of calibration gas.
Connect the calibration adapter and connect it to a source of calibration gas.
Verify that the displayed calibration value meets the concentration label on the gas
cylinder.
6. Press [Y/+] to start calibrating. You can abort the calibration at any time during the
countdown by pressing [MODE].
After a timer countdown, the span calibration is done. The LCD will display whether the
calibration was successful and the reading for that calibration gas.
Note: If the sensor calibration fails, try again. If calibration fails again, turn off the power and
then replace the sensor.
WARNING: Do not replace sensors in hazardous locations

Replacing The Pump
If your QRAE 3 has a pump and it requires replacement, follow these steps. Make sure the
battery is removed before proceeding.
1. Remove the rear cover.
2. The pump is held in place by a metal bracket and two Philips screws. Remove the two
screws.
3. Lift off the metal bracket.
4. The pump has an inlet and outlet that fit tightly over two small pipes inside the pump cavity.
Pressing down on the instrument’s body with one hand, pull the pump straight out.
5. Press a new pump into place (a small amount of wiggling helps), making sure that both the
inlet and outlet from the pump fit snugly over the two pipes.
6. Place the metal bracket over the pump.
7. Insert and tighten the two screws that attach the bracket to the housing.
8. Replace the cover.
9. Turn on the instrument and check for proper pump operation.
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 nonhazardous 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.

Turning the PGM-25XX/D On
With the instrument turned off, press and hold the [MODE] key for 3 seconds, and then
release. The startup process begins. The instrument performs a set of self-tests, while
displaying information about instrument’s settings, configuration, due dates for
calibration and bump tests, etc.
When the startup completes, the PGM-25XX/D displays its normal measurement screen
with instantaneous readings and other information in a fashion similar to what is shown
in the illustration below (depending on the sensors installed).
Turning the PGM-25XX/D 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.
Alarm Signals
The instrument is equipped with audible, visible, and vibration alarms. During its normal
operation, the PGM-25XX/D compares gas concentrations to the programmed alarm
limits for Low, High, TWA and STEL alarms. If the concentration exceeds any of the
preset limits, the loud buzzer, red flashing LED, and vibration alarm are activated
immediately to warn of the alarm condition. In addition, the PGM-25XX/D alarms if the
battery voltage is low, pump is blocked, etc.
When a low-battery alarm occurs, there may be approximately 20 to 30 minutes of
operating time remaining. However, it is recommended that you promptly change or
charge the battery in a non-hazardous location.

Use these menus to change high, low, STEL, and TWA alarm limits -- the points at
which alarms are triggered. It can also change alarm mode (latched or automatic reset)
and alarm output methods (combinations of light, buzzer, and vibration alarm
indications).
Changing Alarm Mode
Auto Reset and Latched alarm modes are supported. A latched alarm stays in alarm until
the user acknowledges the alarm by pressing a key. An auto-reset alarm turns off when
the condition that set off the alarm is no longer present. A user can configure the desired
alarm mode by supplying a password and entering the Programming Menu / Alarms /
Alarm Mode
Bump Testing and Calibration
RAE Systems recommends that a bump test be performed on the PGM-25XX/D prior to
each use. A bump test is defined as a brief exposure of the monitor to the calibration gas
to confirm that the sensors respond to gas and the alarms are functional and enabled.
The PGM-25XX/D multi-gas detector must be calibrated if it does not pass a bump test,
when a new sensor has been installed, or at least once every 180 days, depending on use
and sensor exposure to poisons and contaminants.
Calibration and bump test intervals are user-configurable to match national, regional, and
local regulations.
All calibration and bump test options are available under Programming
Menu/Calibration.
Each bump test or calibration option shows a countdown followed by sensor reading and
pass/fail results.

QRAE 3 User’s Guide
Pumped Models (PGM-25XX)
The PGM-25XX’s internal pump has two speed settings: low or high. The 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 calibration tube, as
illustrated below.
Note: A constant-flow regulator with flow rates from 500cc/min to 1000cc/min should be
used.
Diffusion Models (PGM-25XXD)
RAE Systems’ provided calibration cap should be installed on the diffusion versions of
the instrument when it is being bump tested or calibrated. A constant-flow regulator with
flow rates from 500cc/min to 1000cc/min should be used.
WARNING: Make sure the calibration cap clips on and stays in t correct position during
calibration, as illustrated below.

Zero Calibration
The instrument should be zero calibrated in clean ambient air with 20.9% oxygen. A zero
calibration should precede a span calibration.
Changing Span Value
Use this function to change the gas concentration to be used for bump testing or span
calibration.
Note: If the sensor calibration fails, try again. If calibration fails repeatedly, the sensor(s)
should be replaced. Replace the sensor.
WARNING: Do not replace sensors in hazardous locations.
