CAUTION!
Neveroperatethe monitor when the rear cover is re-
moved. Remove rear cover, sensors,and/or battery only
inan area known to be non-hazardous. Never use the
instrument withthe calibrationadapterinstalled, as this
can cause distortedreadings, apotential safetythreat.
User Interface
The QRAE 3’s user interface consists of the
display and two keys, [MODE] and [Y/+]. The
flippable LCD displays information such as monitored
threats, real-time readings and measurement units,
alarm type (when in alarm, including cal. overdue),
battery status, datalog (if on), and radio and connection
quality (if available).
Charging The QRAE 3 (non-ATEX/IECEx)
Always fully charge the battery before use. Contacts on
the bottom of the QRAE 3 meet the Travel Charger’s
contact pins, transferring power. Make sure the charger
and QRAE 3 are firmly attached. Then connect the AC
Adapter’s barrel plug to the charger, and plug its
transformer into an AC outlet. While charging, the
LED on the Travel Charger glows red. When the
battery is fully charged, the LED glows green.
Barrier Box For ATEX/IECEx Use
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.
Turning The QRAE 3 On
With the instrument turned off, press and hold the
[MODE] key until the audible alarm stops, andthen
release. During startup, the battery, buzzer, vibra-
tion alarm, and LEDs are tested, and then the
QRAE 3 performs self-testing of its other func-
tions. When the main measurement screen appears,
the QRAE 3 is ready for calibration or use.
Note: If the battery is completely empty, then the
display briefly shows the message “Battery
Discharged!” and the QRAE 3 shuts off. You should
charge or replace the battery before turning it on again.
Note: If “Zero At Start,” “Must Calibrate” or
“Must Bump” is set, you will be prompted to
perform the appropriate calibration before using the
instrument.

Turning The QRAE 3 Off
Pressandhold[MODE].A5-secondcountdowntoshut-
offbegins.Continuepressingonthe keyfor theentire
shutoff process.Otherwise,theshutoff operationis
canceledandtheQRAE3 continuesnormal operation.
Whenthecountdown ends and the screen displays “Unit
Off!” release your finger from the [MODE] key. The
QRAE 3 is now off.
Testing The Alarm
Under normal-operation mode and non-alarm condi-
tions, the buzzer, vibration alarm, LED, and backlight
can be tested anytime by pressing[Y/+] once. If any
alarm does not respond, check the AlarmSettings in
Programming Mode to make sure all alarms are
enabled. If any alarms are enabled but are not
functional, do not use the instrument.
Calibration
Make sure all sensors have warmed up before
attempting any calibration. If a sensor’s reading
shows “- -” on the display, the sensor is not ready.
The QRAE 3 diffusion model requires a calibration
adapter. Set it over the sensors, tighten the knob to
secure it, and connect a hose from a calibration gas
regulator. The pumped model requires a T
calibration tube. Attach that to the instrument’s
external filter and to the calibration gas regulator.
CalibratetheQRAE3usingafixed-flowregulator(flow
ratebetween0.5and1.0liters per minute):
1.Tobegincalibration, connect thezeroair or
calibration gas cylinder, flow regulator,and
calibration adapter tothe QRAE 3.
2.Enter ProgrammingModebypressingandholding
[MODE]and[Y/+]simultaneouslyuntilthepassword
screenappears.(Apasswordisnotnecessaryin
Advanced mode.)
3.Input the 4-digit password. (Thedefault password is
“0000.” If you do not know the password, select
“Done.”) Then follow the instructions for individual
ormultiplebump,zeroand span calibration.
Important!After abump testorcalibration,remove
the calibrationadapter or Tconnection toensure
correct readings.
Zero & Fresh Air Calibration
The QRAE 3 should be zero-calibrated in cleanair
with 20.9% oxygen or with a cylinderof clean zero air.
In Programming Mode, press[MODE] to select “Multi
Zero.” Press [Y/+] toselectit. Thenpress[Y/+]tostart
a FreshAir calibration for the listed sensors. All are
fresh-air calibrated at once. During calibration, the
screen says, “Calibrating.” When done, each sensor is
shown, accompanied by the word “Pass.”
To zero calibrate individual sensors:
1. Select “Single Sensor Zero” and select a sensor.
2. Press[Y/+]toselecta sensor tozerocalibrate.
3. Starttheflowofthezerogas,ifused,andpress[Y/+].
4. The screen says, “Calibrating” and counts down.
5. When done, it says, “Zero Calibration Passed” (the
reading shouldbe 0 or verycloseto itfor toxic gas
sensors,and 20.9% Vol. foran oxygen sensor).
Shut offthe flowof zero air(ifused) andremovethe

Span Calibration (Single Or Multi)
In Programming Mode, and with “Multi Sensor
Span” or “Single Sensor Span” highlighted:
1. Press [Y/+]. The screen displays the sensor(s) to be
calibrated.
· Multi: The list is shown.
· Single: Select asensor and press [Y/+].
2. Attach the calibration adapter or T connector.
Connect the calibration gas cylinder’s flow
regulator to the QRAE 3, and start the gasflow.
3. Press [Y/+] to start calibration.
4. Uponcompletion, a pass/fail calibration result
appears and the readings are shown (they should be
within ±10% of the span gas value).
Turn off the gas and remove the calibration
adapter or T connector.
Bump (Functional) Testing
RAE Systems recommends periodic bump testing to
confirm that the sensors and alarms are functional.
Test each sensor with an appropriate test gas in a
concentration not less than the sensor’s low alarm
setting. To pass, each sensor should go at least to a
low alarm. With the QRAE 3 in Normal Mode:
1. Connect thecalibration gas cylinder,flowregulator,
and calibrationadapter or Tconnector to the QRAE
3and start thegasflow.
2. Make sure theunitgoes intoatleast alowalarmfor
eachofthetestedsensors andthat thebuzzer
producesatleast two beeps per second,the LED
lights flash on and off, and the vibration alarm
functions.The displaybacklightshouldilluminate
and an alarmmessage should be showninthe
display.
3. Turn off the gas flow.
Remove the calibration adapter or Tconnector.
Multi Or Single Bump Testing
In Programming Mode, and with “Calibration/Multi
Bump” or “Calibration/SingleBump” highlighted:
1. Press [Y/+].The screen displays the sensor(s) to be
bump tested.
· Multi: The listisshown.
· Single: Select asensorand press[Y/+].
2. Attach the calibration adapter orT connector.
3. Connect the calibration gas cylinder’s flow regulator
tothe QRAE 3,and start the gasflow.
4. Press [Y/+] to start the bump test.
5. Upon completion,a screen labeled “Bump Test
Results” is shown with the sensor name(s) and
value(s), plus the word “Pass” or “Fail.”
6. Turn off the gas and remove the calibration
adapter or T connector.
If a sensor fails a bump test, try to calibrate it. If it
does not calibrate, it should be replaced.
Note: Users are recommended to refer to ISA-
RP12.13, Part II-1987 for general information
on installation, operation, and maintenance of
combustible gas detection instruments.
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.
Wireless Operation
If your QRAE 3 is equipped with a wireless
modem, its settings are controlled via the menu
items under “Wireless.” In order to save time while
operating the QRAE 3 in a network, it is best to
configure the settings before taking the QRAE 3
into the field. Consult the User’s Guide for more
detailed instructions.
1. Enter Programming Mode bypressingandholding
[MODE]and[Y/+]simultaneouslyuntil the
passwordscreenappears.
2. Input the 4-digit password. (The default password
is “0000.”)
3. Press [MODE] repeatedly until “Wireless” is
highlighted.
4. Press [Y/+] to select WirelessSettings.
