MultiRAE User’s Guide
3.1.2 LCD Flip
The MultiRAE senses its vertical/horizontal orientation, and automatically flips the display if it is
inverted, making it easy to read if the MultiRAE is upside down. (You can turn this feature on or off in
Programming Mode, under “Monitor.”)
As the MultiRAE is tilted, the sensor detects
its orientation and inverts the screen when
it past its horizontal position.
3.1.3 Keys & Interface
The MultiRAE has three buttons:
Y/+
MODE
N/-
In addition to their labeled functions, the keys labeled [Y/+], [MODE], and [N/-] 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.
Three 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 [Y/+] key, the center pane corresponds to the [MODE]
key, and the right pane corresponds to the [N/-] key. Here are examples that show the relationships of the
keys and functions:
In addition to the functions described above, any of the buttons can be used to manually activate display
backlighting. Press any button when the backlighting is off to turn it on.

MultiRAE User’s Guide
4 Battery
Always fully charge the battery before using the MultiRAE. Its Li-ion battery is charged by placing the
MultiRAE in its cradle or using the travel charger. Contacts on the bottom of the instrument meet the
cradle’s contact pins, transferring power.
Note: Before setting the MultiRAE into its charging cradle or attaching its travel charger, visually inspect
the contacts to make sure they are clean. If they are not, wipe them with a soft, dry cloth. Do not use
solvents or cleaners.
WARNING
To reduce the risk of ignition of hazardous atmospheres, recharge, remove or replace the battery
only in an area known to be non-hazardous!
4.1 Using The Charging Cradle
Follow this procedure to charge the MultiRAE:
1. Plug the AC/DC adapter into the MultiRAE’s cradle.
2. Plug the AC/DC adapter into the wall outlet.
3. Place the MultiRAE into the cradle and press down until it is locked in place.
The MultiRAE begins charging automatically. The LED in the cradle should glow red to indicate
charging. When charging is complete, the LED in the cradle glows green.
4.2 Using The Travel Charger
Follow these steps to use the travel charger.
Before attaching the travel charger, check that it is aligned correctly with the base of the MultiRAE.
There are two alignment points on one side and one alignment point on the other side, designed to mate
with matching points on the bottom of the MultiRAE:
1. Check bottom of MultiRAE
Travel Charger’s alignment pins
for correct orientation with the
MultiRAE.
2. Align travel charger with
bottom of MultiRAE.
3. Press travel charger onto
bottom of MultiRAE.
5. Make sure the travel charger
is firmly attached.
14
MultiRAE User’s Guide
Next, put the plug from the power supply into the jack on the side of the travel charger:
Plug the other end of the charger into a power source (AC outlet or 12VDC mobile power port, depending
on the model). When power is applied and the MultiRAE’s battery is charging, the LED glows red. The
LED glows green when the battery is fully charged.
4.3 Replacing A Battery
The MultiRAE battery packs are plug-and-play, and can be replaced on the go without tools. To replace
the MultiRAE battery:
1. Remove the battery adapter from the instrument by sliding the tab and tilting out the adapter.
Note: The belt clip and rubber boot are removed in the illustration for clarity. They can be left on
while replacing a battery.
2. Tilt a fully charged battery (or alkaline battery adapter) into the battery compartment and place it in the
instrument.
3. Slide the tab back into place to secure the battery.
4.4 Battery States
The battery icon on the display shows how much charge is in the battery and alerts you to any charging
problems.
Full charge
2/3 charge
1/3 charge
Low charge
Battery alert
When the battery’s charge falls below a preset voltage, the instrument warns you by beeping
once and flashing once every minute, and the “empty battery” icon blinks on and off once per
second. The instrument automatically powers down within 10 minutes, after which you will
need to either recharge the battery, or replace it with a fresh one with a full charge.
4.5 Alkaline Battery Pack
An alkaline battery adapter is supplied with each instrument. The adapter (part number M01-3052-000 or M013054-000) is installed and removed just like the rechargeable battery. It accepts four AA alkaline batteries (use
15
MultiRAE User’s Guide
only Duracell MN1500) and provides approximately 8 hours of normal operation. (An optional rechargeable
lithium-ion battery pack, part number PN: M01-3053-000, is also available.)
Note: The vibration alarm is disabled whenever the alkaline adapter is used.
To replace the alkaline adapter’s batteries:
1. Remove the hex-socket screw at the end of the adapter.
2. Lift the cover off the battery compartment.
3. Insert four fresh AA batteries as indicated by the polarity (+/-) markings.
4. Replace the cover and replace the hex screw.
IMPORTANT!
Alkaline batteries cannot be recharged. The instrument’s internal circuit detects alkaline battery pack and
will not allow recharging. If you place the instrument in its Travel Charger or Charging Cradle, the
alkaline battery will not be recharged. The internal charging circuit is designed to prevent damage to
alkaline batteries and the charging circuit when alkaline batteries are installed inside the instrument. If
you try to charge alkaline batteries installed in the instrument, the Charging Cradle or Travel Charger’s
charging LED does not glow, indicating that it will not charge them.
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.
Note: When replacing alkaline batteries, dispose of old ones properly.
4.6 Proper Battery Disposal

5 Turning The MultiRAE On And Off
5.1 Turning The MultiRAE On
With the instrument turned off, press and hold the [MODE] key until the audible alarm stops, and then release.
When starting up, the MultiRAE turns the backlight on and off, beeps once, blinks once, and vibrates
once. A RAE Systems logo (or a company name) should appear first.
This is followed by a progression of screens that tell you the MultiRAE’s current settings:
•
•
•
•
•
•
•
•
Product model number, serial number and firmware version.
List of installed sensors.
Current date, time and temperature.
User mode,

5.4 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 try to restart the pump by pressing the Y/+ button. If the pump
does not restart, and the pump stall alarm continues, consult the Troubleshooting section of this guide or
contact RAE Systems Technical Support.
Note: Pump Status is not indicated on diffusion MultiRAEs.

7.3.1 Editing And Selecting Parameters And Sensors
There are a few basic ways to edit parameters, select sensors, and perform other activities in the
MultiRAE. The actions performed by pressing keys always match 1-to-1 with the boxes along
the bottom of the display and the three 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 buttons,” 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.
7.3.2 Calibration
Use this menu to perform zero or span calibration for one or more sensors, and change the gas concentration value
assumed to be used in span calibration, as well as zero calibration and calibration reference gas.
21
MultiRAE User’s Guide
7.3.2.1
Fresh Air
This procedure determines the zero point of the sensor calibration curve for all the sensors that require a
zero calibration.
7.3.2.2
Multi Sensor Span
Depending on the configuration of your MultiRAE and span gas you have, you can perform a span
calibration simultaneously on multiple sensors.
7.3.2.3
Single Sensor Zero
This allows you to perform zero (fresh air) calibration on individual sensors.
7.3.2.4
Single Sensor Span
Instead of performing a span calibration on more than one sensor simultaneously, you can select a single sensor
and perform a span calibration.
7.3.2.5
Cal. Reference
It is sometimes desirable to calibrate a sensor (PID for VOC, and LEL) with a specific gas for best
response to a gas you are surveying. Changing the gas requires selecting the right calibration reference
gas in the MultiRAE. Choose the sensor, and then select from the list of reference gases.
7.3.2.6
Change Cal. Gas
You can change the calibration gas for the MultiRAE’s PID and LEL sensors. Select from a custom list that you
create (My List), the last ten gases used, the built-in gas library for your PID lamp (taken from RAE Systems’
Technical Note TN-106), and custom gases. Each gas is shown in the list for selection and the screen automatically
changes to show its full name, chemical formula, molecular weight (M.W.) and correction factor (CF).
22
MultiRAE User’s Guide
7.3.2.7
Multi Cal Select
You can select one or more sensors to be calibrated at a time. An “X” in a box to the left of a sensor’s
name indicates it is selected.
7.3.2.8
Change Span Value
You can individually set the span gas value for each sensor. The units of measure (ppm, %LEL, etc.) are
shown on the display.
7.3.2.9
Change Span2 Value
If your MultiRAE is equipped with a PID that has ppb capabilities, you can set the span gas value for a
third calibration point (Span2). The unit of measure (ppb) is shown on the display.
7.3.3 Measurement
The submenus for Measurement include Sensor On/Off, Change Measurement Gas, and VOC and
Gamma (if equipped) Measurement Units.
7.3.3.1
Sensor On/Off
You can turn sensors on or off via this set of submenus. An “X” in a box to the left of a sensor’s name
indicates it is turned on.
23
MultiRAE User’s Guide
7.3.3.2
Change Meas. Gas
The MultiRAE has extensive onboard gas libraries for combustible gases and VOCs that you can use to
configure your MultiRAE to automatically apply the appropriate correction factors and produce readings
in the units of the desired combustible gas or VOC.
Measurement gases are organized in four lists:
•
•
•
•
My List is a customized list of gases that you create. It contains a maximum of 10 gases and can only
be built in ProRAE Studio II on a PC and transferred to the instrument. Note: The first gas in the list
is always isobutylene (it cannot be removed from the list).
Last Ten is a list of the last ten gases used by your instrument. The list is built automatically and is
only updated if the gas selected from Custom Gases or Library is not already in the Last Ten. This
ensures that there is no repetition.
Gas Library is a library that consists of many of the gases found in RAE Systems’ Technical Note
TN-106 (available online at www.raesystems.com).
Custom Gases are gases with user-modified parameters. Using ProRAE Studio II, all parameters
defining a gas can be modified, including the name, span value(s), correction factor, and default alarm
limits.
7.3.3.3
Measurement Units
In some cases, the measurement unit for displaying data from sensors can be changed. Standard available
measurement units include:
Abbreviation

7.3.4 Alarms
Use this menu 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).
7.3.4.1
Alarm Limits
There are four groups of alarm settings, and each allows you access to setting the alarm point for each
individual sensor (for example, if the MultiRAE is equipped with three sensors, then you can set the high
alarm point for all three separately, low alarm for all three separately, etc.).
Settings:
•
•
•
•
High Alarm
Low Alarm
STEL Alarm
TWA Alarm
Note: Some alarm settings are not applicable to all sensors. If a setting is irrelevant to a sensor (for
example, STEL for a gamma radiation sensor), then that sensor does not appear in the list.
7.3.4.2
Alarm Mode
You can program the MultiRAE so that there are two ways to shut off an alarm:
Auto Reset
Latch
7.3.4.3
When the alarm condition is no longer present, the alarm stops and resets itself.
You can manually stop the alarm when one is triggered. The latched setting only
controls alarms for High Alarm, Low Alarm, STEL Alarm, and TWA alarm.
Alarm Settings
You can enable/disable any combination of light (LEDs), buzzer, and vibration alarms.

7.3.4.4
Comfort Beep
A Comfort Beep is a single beep of the audible alarm at 60-second intervals that reminds the person using
the MultiRAE that it is functioning. It can be turned on or off.
7.3.4.5
Man Down Alarm
The Man Down Alarm is a critical and potentially lifesaving safety feature of every MultiRAE. 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 MultiRAE blasts the alarm not only
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 the command center, that a person is down, so
that help can get on the way quickly.
25
MultiRAE User’s Guide
When the Man Down feature is on and there is no gas or radiation alarm, the MultiRAE 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 MultiRAE to its normal operation. Pressing [N/-] 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)
Motion 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 MultiRAE’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 [N/-] during the countdown, answering the “Are You OK?” question with “No,” the
Man Down alarm starts.
If wireless connectivity is enabled, a Man Down message is also sent to remote observers.
7.3.5 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 MultiRAE memory is sufficient to record six months’ worth of data for
five 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.
7.3.5.1
Clear Datalog
This operation erases all data stored in the datalog.
Note: Once the datalog is cleared, the data cannot be recovered.
7.3.5.2
Datalog Interval
Intervals are shown in seconds. The default value is 60 seconds. The maximum interval is 3600 seconds,
and the minimum is 1 second.
26
MultiRAE User’s Guide
7.3.5.3
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.
7.3.5.4
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 1.04 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
7.3.5.5
Datalog Type
The instrument offers three options for starting the datalogging process:
Auto
Manual
Snapshot
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).
Datalogs only during snapshot (single-event capture, initiated by pressing [MODE])
sampling.
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
[N/-] 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. You can turn it off by pressing [Y/+] again.
If datalogging is running, you can leave it running. However, if you want to turn it off,
follow this procedure:
1. Press [N/-] repeatedly to step through the screens until you reach the screen that says,
“Datalog Running.”
2. When the screen says “Stop Datalog?” press [Y/+] to stop datalogging. The screen
displays “Datalog Stopped” for a few seconds, before displaying “Start Datalog?” and
the datalog interval. You can restart it anytime by pressing [Y/+].
About Snapshot Datalog
When the instrument is in Snapshot datalogging mode, it captures a single “snapshot” of the data at the
moment of your choosing. Whenever the instrument is running in Hygiene Mode, all you have to do is
press [MODE] each time you want to capture a snapshot of the data at that instant.
No snapshot.
Press [MODE] for snapshot.

display that says, “Ready…Start sampling?” press [Y/+] to start. The pump turns on and the instrument
begins collecting data. To stop sampling, press [N/-] while the main display is showing. You will see a
new screen that says, “Stop sampling?” Press [Y/+] to stop sampling. Press [N/-] if you want sampling to
continue.
7.3.7.3
Pump Speed
If the MultiRAE 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.
7.3.7.4
Zero At Start
If your MultiRAE has been configured to perform a zero (fresh air) calibration upon startup, called Zero
At Start, then the startup routine is interrupted so that you can perform a fresh air calibration.
If you do not want to perform a zero calibration, press [MODE] to bypass it. If you start a zero calibration
and want to abort it, press [N/-], and the calibration stops and the main display is shown.
7.3.7.5
Fast Startup
Fast Startup skips showing you many settings and is best suited to environments where the MultiRAE is turned
on and off very often during a given day. If Fast Startup is not selected, then when the instrument starts, it
shows you details of each sensor, including calibration information, high and low alarm settings, etc.

8 Calibration And Testing
8.1 Bump Testing And Calibration
RAE Systems recommends a bump test be performed periodically on the MultiRAE. A bump test is
defined as a brief exposure of the monitor to the calibration gas to show response and trigger the lowest
alarm set point for each sensor.
•
•
The MultiRAE 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.
8.1.1 Bump (Functional) Testing
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 alarm 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.
8.2 Zero/Fresh Air 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 MultiRAE Calibration Adapter. Using a calibration
adapter is not necessary for calibration in fresh air.
8.2.1 Zero Calibration For A CO2 Sensor
Important! If your MultiRAE is equipped with a CO2 sensor, it must be zero calibrated using 100%
Nitrogen (N2), which is inert, instead of fresh air or zero air. You can also use CO2-free isobutylene,
which is convenient to use for zeroing the CO2 sensor and span calibrating a VOC sensor.
8.2.2 Fresh Air Calibration
This procedure determines zero points of most sensors.
To perform a fresh air calibration, use a calibration adapter to connect MultiRAE to a “fresh” air source
such as that provided by a cylinder. The “fresh” air is clean ambient air without impurities and an oxygen
content of 20.9%. If a pure air cylinder is not available, any clean ambient air without detectable
contaminants, or clean ambient air drawn through a charcoal filter can be used.
At the Calibration menu, select “Fresh Air” by pressing [Y/+] once to enter fresh air calibration.
30
MultiRAE User’s Guide
After a timer countdown, the zero calibration is done. The LCD will display whether the calibration was
successful along with the calibrated readings in fresh air.
Press [Y/+] to start the calibration. A countdown screen is shown. You can abort the calibration at any
time during the countdown by pressing [N/-].
If the calibration reaches its conclusion, the display shows the sensor names and tells you whether each
calibration passed or failed, followed by the sensor readings.
8.2.3
Single-Sensor Zero Calibration
Select the sensor and then start the calibration by pressing [Y/+]. You can abort the procedure anytime by
pressing [N/-].
8.3 Span Calibration
This procedure determines the second point of the sensor calibration curve for the sensor.
MultiRAE Equipped With A Pump
With its pump speed setting of low or high, a MultiRAE normally draws in air at a flow rate of between
200 cc/min and 300 cc/min. RAE Systems recommends that a calibration cap to be used with calibration
gas flow rates from 500 cc/min to 1000 cc/min.
WARNING: Make sure the calibration cap clips on and stays in the correct position during
calibration, as illustrated below. Otherwise, the calibration cap must be manually held in the
correct position.

the flow of calibration gas. (The
Calibration Adapter has small
grooves on its underside to allow
gas to escape after passing over
the sensors.
8.3.1 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 MultiRAE.
1. Attach the calibration adapter and gas to the MultiRAE.
2. Start the flow of gas and then press [Y/+] to begin calibration. A countdown screen is shown.
You can abort the calibration at any time during the countdown by pressing [N/-].
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.
32
MultiRAE User’s Guide
8.3.2 Single-Sensor Span Calibration
This procedure determines a sensor’s reading when its target gas is present.
1. At the Calibration Menu, select “Single Sensor Span.”
2. Select a sensor from the list.
3. Connect the calibration adapter and connect it to a source of calibration gas.
4. Start the flow of calibration gas.
5. 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 [N/-].
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, replace the sensor.
Warning: Do not replace sensors in hazardous locations.
8.4 Testing The Gamma Sensor
The gamma radiation sensor does not require user calibration. You can check it by placing a check-source
on the rear of the MultiRAE equipped with a gamma sensor to check the readings. There is a raised dot on
the rubber boot that marks where the sensor is located inside the instrument.

10 Maintenance
The MultiRAE requires little maintenance, aside from replacing sensors, the filter, and the battery. If the
instrument is equipped with a pump, it may need replacement, as well. If the instrument has a PID, then
the PID sensor lamp and sensor electrode panel may require periodic cleaning.
10.1 Removing/Installing The Rubber Boot
In order to open the MultiRAE, it is necessary to remove the belt clip and the rubber boot. Note that there
are two hex screws on the bottom rear side that secure the boot.
1. Remove the belt clip by unscrewing the Philips screw (pumped version only).
2. Remove the two hex screws located below the battery area.
3. Pull the bottom of the boot back over the rear side of the instrument.
4. Carefully slide the boot upward, and slide it over the D-ring and clamp.
10.2 Replacing The Filter
Pumped Version
If a filter is dirty or clogged, remove it by unscrewing it from the inlet. Discard it and replace it with a
new filter.
Diffusion Version
If the filters appear dirty, remove the rear cover to access them (this requires removing the rubber boot first).
Remove the four screws
holding the sensor
compartment cover in
place.
Remove the O-rings and then remove the filters.
Replace them with new filters and return the Orings to their proper locations.
Replace the rear cover
and tighten the four
screws.
10.3 Replacing The Inlet
When you remove the nozzle, unscrew it in the same manner as the filter. When replacing it, make sure

10.4 Removing/Cleaning/Replacing A PID (Pump Version Only)
Note: If you need to access a PID for cleaning or replacement, you must remove the rubber boot and belt
clip first.
1. Turn off the instrument.
2. Remove the four screws in holding the MultiRAE sensor compartment cover in place.
3. Remove the cover to expose the sensors.
4. Gently lift out the PID module with your fingers.
5. If the module requires replacement (for example, because the lamp does not illuminate, or the
module has been used past its expiration date), place a new module into the slot, being careful to
match the indexing keys. The sensor can only go into its slot one way.
6. If you want to open the sensor module to inspect and clean the lamp and sensor electrode panel,
you must use the special tool (part number G02-0306-003, package of three). Its “C”-shaped end
has small “teeth” inside. Slide the tool so that the teeth slip into the notch between the module’s
cap and body:
7. Gently pry up the cap using a rocking motion:
8. Once the cap is removed, set it aside.
9. Now lift the sensor electrode panel from the module:
10. Clean the sensor electrode panel in a solution of methanol lamp cleaner (included, along with
cleaning swabs, in a PID Lamp Cleaning Kit, part number 081-0002-000), and allow it to dry.
36
MultiRAE User’s Guide
11. Clean the lamp’s window with a cleaning swab dipped in methanol lamp cleaner, and allow it to
dry. Do not touch the lamp window with your fingers, as the residual oils will shorten its life.
12. Inspect the electrical contacts. Clean them with a swab dipped in lamp cleaner if they appear to
need cleaning:
13. Reassemble the sensor module by placing the sensor electrode panel back in place and firmly
pressing the cap back onto the top.
14. Place the sensor module back into the MultiRAE. Make sure the index points are aligned (it can
only go in one way).
15. Reinstall the rear cover.
16. Tighten all four screws.
Note: Always calibrate the MultiRAE after replacing the sensor module.
10.5 Removing/Cleaning/Replacing Sensor Modules
WARNING! Do not replace a sensor in hazardous locations.
All sensors are located inside the sensor compartment in the upper half of the MultiRAE. They are
accessed by removing the cover that is held on by four screws.
1.
2.
3.
4.
5.
Turn off the instrument.
Remove the four screws holding the sensor compartment.
Remove the cover. The sensors are plugged into the slots.
Gently lift out the desired sensor module with your fingers.
Install the replacement sensor. It can only go into its slot one way. The connector inside the
MultiRAE and the indexing guides are good visual indicators of how to set the sensor into
position. Make sure the indexing keys are aligned and that the sensor is seated firmly.

10.6 Replacing The Pump
If your MultiRAE 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. Pressing down on the gas plate with one hand, pull the pump straight out. It has an inlet and outlet
that are held in the two holes with rubber gaskets to the left of the pump cavity.
5. Press a new pump into place (a small amount of wiggling helps), making sure that both the inlet
and outlet from the pump go into the two holes.
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.
11 Alarms Overview
The MultiRAE 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.
Note: The vibration alarm is automatically disabled whenever the alkaline adapter is used.
11.1 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 MultiRAE user and a remote safety officer (if wireless is
enabled) of the alarm condition.
In addition, the MultiRAE alarms if one of the following conditions occurs: battery voltage low, pump
blocked, PID lamp failed, 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 non-hazardous location.
11.2 Changing The Alarm Mode
Your choices are Auto Reset and Latched. A latched alarm stays on until you acknowledge the alarm by
pressing a button. 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 [Y/+].
3. Press [Y/+] to save your selection.
