WARNINGS
Read Before Operating
The MultiRAE User’s Guide must be carefully read by all
individuals who have or will have the responsibility of
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!
Never operate the monitor when the rear cover is re-
moved. Remove rear cover, sensors, and/or battery only
in an area known to be non-hazardous. Never use the
instrument with the calibration adapter installed, as this
can cause distorted readings, a potential safety threat.
User Interface
The MultiRAE’s user interface consists of the
display and three keys, [Y/+], [MODE] and [N/-].
The flippable LCD displays information such as
threat real-time readings and measurement units,
monitored threat, alarm type (when in alarm, including
cal. overdue), battery status, datalog (if on), and radio
and connection quality (if available).
Charging The MultiRAE
Always fully charge the battery before use. Contacts on
the bottom of the MultiRAE meet the Travel Charger’s
or Charging Cradle’s contact pins, transferring power.
Make sure the charger and MultiRAE 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 cradle glows red.
When the battery is fully charged, the LED glows
green.
Turning The MultiRAE On
With the instrument turned off, press and hold the
[MODE] key until the audible alarm stops, and then
release. During startup, the battery, buzzer,
vibration alarm, and LEDs are tested, and then the
MultiRAE performs self-testing of its functions.
When the main measurement screen appears, the
MultiRAE is ready for calibration or use.
Note: If the battery is completely empty, then the
display briefly shows the message “Battery Fully
Discharged,” and the MultiRAE shuts off. You should
charge the battery or replace it with a fully charged
battery before turning it on again.
Note: If Fast Startup is enabled on the instrument,
fewer screens are shown during startup, compared
to Normal Startup sequence.
Turning The MultiRAE Off
Press and hold [MODE]. A 5-second countdown to shut-
off begins. You must continue pressing on the key for the
entire shutoff process. If you remove your finger from the
key during the countdown, the shutoff operation is
canceled and the MultiRAE continues normal operation.
When the countdown ends and the screen displays “Unit
Off,” release your finger from the [MODE] key. The
MultiRAE 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 Alarm Settings 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
The MultiRAE can be automatically bump tested and
calibrated using the AutoRAE 2 Test and Calibration
System (refer to its User’s Guide for instructions).
Manually calibrate using a fixed-flow regulator (flow rate
between 0.5 and 1.0 liters per minute) and the supplied
special calibration adapter that covers the gas inlet:
1. To begin calibration, connect the zero air or
calibration gas cylinder, flow regulator, and calibration
adapter to the MultiRAE.
2. Enter Programming Mode by pressing and holding
[MODE] and [Y/+] simultaneously until the password
screen appears.
3. Input the 4-digit password. (The default password is
“0000.” If you do not know the password, select
“Done.”) Then follow the instructions for individual
or multiple zero and span calibration.
Important! After a bump test or calibration, remove the
calibration adapter to ensure correct readings.
Zero & Fresh Air Calibration
The MultiRAE should be zero-calibrated in clean air
with 20.9% oxygen or with a cylinder of clean zero air.
In Programming Mode, select “Fresh Air.” Then:
Press [Y/+] to start a Fresh Air calibration for the listed
sensors. All are fresh-air calibrated at once.
To individually zero calibrate sensors:
1. Select “Single Sensor Zero” and select a sensor.
2. Press [Y/+] to select a sensor to zero calibrate.
3. Start the flow of the zero gas, and press [Y/+].
4. The screen says, “Zeroing” and counts down.
5. When done, it says, “Zero Calibration Passed” (the
reading should be 0.0 ppm or very close to it for toxic
gas sensors, and 20.9% Vol. for an oxygen sensor).
6. Shut off the flow of zero air (if used) and remove
the calibration adapter.
Note: If your MultiRAE is equipped with a CO2 sensor,
it must be zero calibrated using 100% Nitrogen (N2), or
isobutylene, instead of fresh air or zero air.
Span Calibration
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 a sensor and press [Y/+]
2. Attach the calibration adapter, and connect the
calibration gas cylinder’s flow regulator to the
MultiRAE, and start the gas flow.
3. Press [Y/+] to start calibration.
4. Upon completion, a pass/fail calibration result
appears and the readings are shown (they should be
within ±10% of the span gas value).
5. Turn off the gas and remove the calibration
adapter.
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 MultiRAE in Normal Mode:
1. Connect the calibration gas cylinder, flow
regulator, and calibration adapter to the
MultiRAE and start the gas flow.
2. Make sure the unit goes into at least a low alarm
for each of the tested sensors and that the buzzer
produces at least two beeps per second, the LED
lights flash on and off, and the vibration alarm
functions. The display backlight should
illuminate and an alarm message should be
shown in the display.
3. Turn off the gas flow.
4. Remove the calibration adapter.

Basic Menu Navigation In Hygiene Mode
Pressing [MODE] repeatedly
allows you to step through
the screens as shown here.
Note: The gray box indicates
the datalog functions when
datalogging is in Manual mode.
When datalogging is in
Automatic mode, this screen
does not appear. Refer to the
User’s Guide for information
on selecting Automatic, Manual,
or Snapshot datalogging.
