2 General Information
The MultiRAE is a family of multi-threat gas detectors that combine continuous monitoring capabilities
for volatile organic compounds (VOCs), toxic and combustible gases, and radiation, with Man Down
Alarm functionality in one highly portable instrument. MultiRAE monitors offer an industry-leading
selection of interchangeable field-replaceable electrochemical, combustible, infrared, PID
(photoionization detector), and gamma radiation sensors to fit a wide variety of applications. The
MultiRAE family’s wireless capability elevates worker protection to the next level by providing safety
officers real-time access to instrument readings and alarm status from any location for better visibility and
faster response.
Notes:
NDIR combustible sensors are not supported on the diffusion version with CSA certification.
The PID sensor requires a pumped configuration.
If a %Vol. NDIR sensor is installed in an instrument, a catalytic bead %LEL sensor must also be
installed in the instrument for CSA certification.

3 User Interface
The MultiRAE’s user interface consists of the display, alarm LEDs, an alarm buzzer, and three keys.
3.1 Display Overview
The LCD display provides visual feedback that includes the sensor types, readings, alarm status, battery
condition, and other information.
3.1.1 Status Indicator Icons
Along the top of most screens are status indicators that tell you whether a function is operating and/or its
strength or level.

3.1.2 Keys And Interface
The MultiRAE has three keys:
Y/+
MODE
N/-
In addition to their labeled functions, [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 keys can be used to manually activate display
backlighting. Press any key when the backlighting is off to turn it on. A subsequent key press is required
to carry out an actual function corresponding to that key.
3.1.3 LCD Flip
The MultiRAE senses its vertical/horizontal orientation, and can automatically flip the display 180
degrees, making it easy to read if the MultiRAE is upside down. (You can turn this feature on or off in
Programming Mode, under “Monitor/LCD Flip.”)
As the MultiRAE is tilted, the gravity sensor
detects its orientation and inverts the screen
when it is past its horizontal position.

MultiRAE User’s Guide

3.1.4 Key Mapping When LCD Is Flipped
When the instrument is inverted and the LCD flips, the keys are mapped to the functions shown
on the screen.

3.2 Screen Display For Various Numbers Of Active Sensors
The MultiRAE family of instruments can display readings from one to six sensors (including dual
sensors), depending on the configuration. In order to maximize readability and the amount of information
shown, the display is automatically reconfigured, according to the number and types of sensors in the
MultiRAE.
If the configuration includes five sensors, and one of them is a PID, then the lamp value (9.8eV or
10.6eV) is shown, along with the currently applied correction factor (CF) and measurement gas.

3.3 Menus
The reading menus are easy to step through by pressing the [N/-] key.
Hygiene Mode: Sampling is continuous, and Hygiene Mode allows you to clear peak and minimum
values at any time.
Search Mode: Samples only when you tell it to sample. This allows you to save sample readings as
individual events in the datalog. You can also clear peak and minimum values.
Note: You can switch between Hygiene and Search modes via the Programming Menu (Select Monitor
and then Operation Mode).
Note: If the instrument is not equipped with a VOC sensor (PID), or is not equipped with an LEL sensor,
then screens for those sensors (VOC Gas Status and LEL Gas Status, respectively) are not shown.
Hygiene Mode
Note: Dashed line indicates automatic progression.

MultiRAE User’s Guide
15
Search Mode
Note: If the instrument is not equipped with a VOC sensor (PID), or is not equipped with an LEL sensor,
then screens for those sensors (VOC Gas Status and LEL Gas Status, respectively) are not shown.
Note: Dashed line indicates automatic progression.
WARNING!
Gamma readings are not taken in Search Mode.

MultiRAE User’s Guide
16
Note: If the Peak or Min is cleared, the Average is also cleared. In addition, each cycle through the main
screen after they are cleared will route from “Ready… Start sampling?” directly to Date and Time if you
press [N/-] (see red line in diagram below), until you perform a new sample. Also, if you start sampling
again and stop sampling, clear the Peak, or clear the Min, it advances to Date and Time, as well.
Note: Dashed line indicates automatic progression.
WARNING!
Gamma readings are not taken in Search Mode.

4 Wireless Control And Submenus
When you step through the main menu, as shown in the previous three diagrams, there are two
screens for wireless communication.
Note: These are only present if the MultiRAE is equipped with a wireless module.
At the Radio On/Off screen, you can turn the radio on or off, if the MultiRAE is in Advanced User
Mode. The radio turns off instantly, but turning on the radio takes a few seconds, so you see ascreen
that indicates the radio is beingturned on. If the instrument is in Basic User Mode, the option for
turning the radio on or off does not appear(you can turn it on or off in Programming Mode).
At the Wireless screen, you can check communication with other wireless devices and get other
useful information about the wireless settings. The Wireless menu is divided into a sequence of
four “pages,” each presenting different information. As you press [Y/+] on each of the “pages,”
you advance to the next one.
Unit ID (unique identifier of the instrument’s radio), Pan ID, and Channel are read-only
parameters that help you to check whether the instrument’s wireless settings are correct (very
helpful for troubleshooting).
The next “page,” Parent ID and Device Type are also read-only. The Parent ID (the ID of the
“Parent”wireless device to which the monitor is connected) is not changeable. The device type
tells you that it is “Standard,” meaning it transmits and receives.
The third “page” is labeled “Ping,” where you can check the signal strength via RSSI (received
signal strength indication) and “ping” the network to confirm an active two-way communication
network. Each time you press [MODE] to “ping” the network, a number of sends is included
under “Sent.” If the network receives the signal and sends one back, which is in turn received by
the MultiRAE, then a number is added under “Received.”
The fourth “page” includes the type of transmitter (Region), Radio Type (model), and Tx Power
(transmission power). These are primarily for diagnostics and troubleshooting.
When you reach the fourth “page,” you can wrap around to the first one by pressing [Y/+].
Otherwise, you can press [N/-] to quit, which advances to the next screen.

5 Battery
Always make sure the batteries are fully charged before using the MultiRAE. Three battery options are
available for the MultiRAE:
1. Standard duration rechargeable Li-ion battery (PN: M01-3053-000)
2. Extended-duration rechargeable Li-ion battery delivering 50% more runtime than the standard
battery (PN: M01-3055-000)
3. Alkaline battery pack for four standard AA-sized batteries (PN: M01-3054-000)
Its standard or extended-duration batteries are charged inside the instrument 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 MultiRAE Desktop 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! Do not mix old and new batteries or batteries from
different manufacturers.
