WARNINGS
Read Before Operating
TheMicroRAE User’s Guide must be carefully read by
all individuals who have orwill have the responsibility
ofusing, maintaining, orservicing thisproduct. The
product will performas designedonly if it is used,
maintained, andservicedinaccordance with the manu-
facturer’s instructions.
CAUTION!
Neveroperate the monitor when the rear coverisre-
moved. Remove rear cover, sensors, and/or batteryor
chargethe batteryonly inanareaknown tobe non-
hazardous. Never use the instrument withthe calibration
adapterinstalled,asthiscancausedistortedreadings,a
potentialsafetythreat.
User Interface
Functions are controlled via the [MODE] and [Y/+]
keys. The display shows information such as
monitored threats, real-time readings and measure-
ment units, alarm type (when inalarm, including cal.
overdue), battery status, datalog (if on), GPS status,
and radio and connection quality (if available).
Turning The MicroRAE On
With the instrument turned off, press andhold the
[MODE] key until the audible alarm stops,and then
release.During startup,it teststhebattery,buzzer,
vibration alarm, LEDs, andinternalfunctions.Thenthe
main readingscreen is shown.
Note: If thebatteryiscompletelyempty,thenthe
display briefly shows the message “LowBattery,” and
theMicroRAEshuts off.Youshouldchargethe battery
beforeturningit onagain.
Note:It takes 45 seconds for some 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.
Note: If Fast Startup is enabled on the instrument,
fewer screens are shown during startup, compared
to Normal Startup sequence.
Charging The MicroRAE
Always fullychargethe battery before use. Contacts on
the bottom of the MicroRAE meet the Travel Charger’s
or Charging Cradle’s contact pins, transferringpower.
Makesurethe chargerand MicroRAE arefirmly
attached. Then connect the AC Adapter’s plug to the
charger,andplugitstransformer intoanACoutlet.
While charging, the LED on thecradle glows red.When
the battery isfully charged, the LED glows green.
Turning The MicroRAE Off
Pressandhold [MODE]. A5-secondcountdownto shut-
offbegins.Youmustcontinuepressingonthekeyforthe

When the countdown ends and the screen displays “Unit
Off,” release your finger from the [MODE] key. The

Testing The Alarms
Under normal-operation mode and non-alarm condi-
tions, the buzzer, vibration alarm, and LEDcan be
tested anytime by pressing [Y/+] once. If any alarm
does not respond, check the Alarm Settings in
Programming Mode or in ProRAE Studio II to make
sure all alarms are enabled. If any alarms are enabled
but are not functional, do not use the instrument.

Bump Testing and Calibration Setup
Important! Test the alarms prior to performing a
bump or span calibration test.
Manuallycalibrate the MicroRAEusing afixed-flow
regulator(refer to User’s Guide for moredetails)andthe
suppliedspecialcalibrationadapterthatcoversthe gas
inlet:
1. Connectthegascylinder,flowregulator,tubing,and
calibrationadapter totheMicroRAE.
2. With the MicroRAE in Normal Mode, enter
ProgrammingModebypressingandholding both
[MODE]and[Y/+] until thepassword screen
appears.
3.Input the 4-digit password. (The default password is
“0000”.)Thenfollowthe menusto selectsingle-or
multi-sensor bumptest,zero,orspancalibration.
Important!Aftera bumptestor calibration, removethe
calibrationadapter toensurecorrectreadings.
Bump (Functional) Testing
Bump test toconfirm that the sensors and alarms are
functional.
Important! Make sure all sensors have warmed up
before performing the bump test.
With the MicroRAE in Programming Mode:
1.Enter the BumpTest or Multi Bump menu. The
calibration gas value for each sensor is shown.
2.In Single Bump, select the sensor to bump test. In
Multi Bump, you do not need to select a sensor.
3.Connect calibration gas to the instrument and start
the flow.
4.Press [Y/+] to start the bump test.
5.After the countdown, the result is shown.
6.Exit bump testing.
Zero & Fresh Air Calibration
Before othercalibrations are performed, the MicroRAE
should be fresh-air calibrated in clean air with 20.9%
oxygen or with a cylinder of clean zero air. The oxygen
sensorshould be calibrated withnitrogen (N2). In
Programming Mode, select “Fresh Air.” Then:
Press [Y/+]tostart a FreshAircalibrationforthelisted
sensors. All are fresh-aircalibratedat once.
Toindividuallyzero calibratesensors:
1. Select “SINGLE ZERO” and select a sensor.
2. Press[Y/+] to select a sensor to zero calibrate.
3. Start the flow of the zero gas, if used, and press
[Y/+].
4. The screen says, “CAL” and counts down.
5. When done, it says, “PASS” (the reading should be
0 or very close to it for combustible and toxic gas
sensors, and 0% Vol. for an oxygen sensor).
6. Shut off the flow of zero air (if used) and remove
the calibration adapter.
Span Calibration
SpanCalibrationdetermines the second point of the
sensor calibration curve for the sensor.
Important! Make sure all sensors have warmed up
before performing a span calibration.
With the MicroRAE in Programming Mode:
1.Enter the Single Span or Multi Span menu. The
calibration gas value for each sensor is shown.
2.In Single Span, select the sensor to calibrate. In
Multi Span, you do notneed to select a sensor.
3.Connect calibration gas to theinstrument and start
the flow.
4.Press [Y/+] to start calibration.
5.After the countdown, the result is shown.
6.Exit span calibration.
