QuickStart Guide

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 re­moved. 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.

Note: If the MultiRAE is equipped with a gamma
sensor, it comes pre-calibrated from the factory and no
calibration is required. You can challenge it anytime
with a radioactive check source.

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 monitored threats,
real-time readings, measurement units, alarm type (when
in alarm, including cal. overdue), battery and pump
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 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 other 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 shut­off 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 Alarms

Under normal-operation mode and non-alarm condi­tions, 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.

Bump Testing and Calibration Setup

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. Connect the gas cylinder, flow regulator, tubing

(must use Teflon tubing for PID sensor), and
calibration adapter to the MultiRAE.

2. With the MultiRAE in Normal Mode, enter

Programming Mode by pressing and holding both
[MODE] and [N/-] 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 menus to select single- or
multi-sensor bump test, zero, or 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, if used, and press [Y/+].

4. The screen says, “Zeroing” and counts down.

5. When done, it says, “Zero Calibration Passed” (the

reading should be 0 or very close to it for VOC and 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).
Note: If a VOC sensor is installed, a second
calibration can be performed to enhance linearity,
requiring different calibration gas.

5. Turn off the gas and remove the calibration
adapter.

Bump (Functional) Testing

Bump test to confirm that the sensors and alarms are
functional.

Important! Test the alarms, as described in panel 6
(above), prior to performing a bump test.

Important! Make sure all sensors have warmed up
before performing the bump test. 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.

With the MultiRAE in Normal Mode:

1. Enter the Bump Test menu. Follow instructions

in panel 7 (above) or use the easy shortcut: Press
both the [Y/+] and [N/-] buttons at the same time
and hold them for 5 seconds. The Multi-Bump
menu then appears.

2. The bump test process consists of two steps, each

requiring its own calibration gas. The LEL and O2
sensors are tested first, followed by the PID sensor.
Press [Y/+] to start the bump test. While the bump
test is being performed, the readings for each sensor
are shown.

3. Once the bump test completes, pass/fail results are

shown for each sensor.

4. Press OK to proceed to the PID sensor test.

Connect Isobutylene gas and press [Y/+] to start the
test. After the test completes, pass/fail results are
shown.

5. Press OK to return to the main measurement

screen.

6. Turn off the gas flow.

7. Remove the calibration adapter.

BATTERY PACKS

A Li-Ion battery pack (PN: M01-3051-000 or M01-

3053-000) and an alkaline battery adapter (PN:
M01-3052-000 or M01-3054-000) are supplied
with each MultiRAE.

There are two types of output power for battery
packs or adapters. The battery pack (PN: M01­3051-000) and adapter (PN: M01-3052-000) are
used for MultiRAE model number PGM-62x0.
Battery pack (PN: M01-3053-000) and adapter
(PN: M01-3054-000) are used for model number
PGM-62x6/PGM-62x8.

The alkaline battery adapter accepts four AA
alkaline batteries (use only Duracell MN1500). Do
not mix old and new batteries or batteries from
different manufacturers.
