2. The firmware version is shown in the display (for example, “F1.0” indicates firmware
version 1.0).
3. The sensor is tested. If the sensor is okay, it warms up, and there is a countdown.
(The countdown time depends on the sensor.)
Note: If the sensor is depleted or does not check out satisfactorily, an error message
of “E01” flashes on the display. The ToxiRAE 3 should not be used until the sensor is
replaced. (Shut off the ToxiRAE 3 by pressing and holding [MODE] until you see the
countdown and the display shows “oFF.”)
4. Once the countdown is complete, the type of sensor is displayed (for example, “CO”),
“OK” is displayed below the battery icon, and the reading is also shown (for example
0 ppm). The ToxiRAE 3 is now in Normal Mode and is ready for use.
6. Turning The ToxiRAE 3 Off
Press and hold [MODE]. In 2 seconds, a 5-second countdown to shutoff begins. You
must hold your finger 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 ToxiRAE 3
continues normal operation.
When you see “oFF,” release your finger from the [MODE] key. The ToxiRAE 3 is now
off.
Caution: The alarm is very loud. During shutdown, you can mute most of the sound by

10. Operating The ToxiRAE 3
10.1. Mode Overview
The ToxiRAE 3 has three operational modes:
•Normal — see page 12 for detailed instructions.
•Programming — see page 16 for detailed instructions.
•Diagnostic — see page 27 for detailed instructions.
The following is an overview of the three modes:
Normal Mode is the default mode. It is accessed when you turn on the ToxiRAE 3.
There are no access restrictions (you do not need a password), and it provides the
indications and data you need most for typical monitoring applications There are two
sub-modes of operation, Display and Disposable. Display includes:
•Readings of carbon monoxide (CO) or hydrogen sulfide (H2S), depending on the
sensor.
•STEL (short-term exposure limit).
•TWA (time-weighted average).
•Battery level.
•Recent alarms.
Disposable only shows the number of days left until a bump test is required and
information when an alarm is triggered.
Both sub-modes of Normal Mode also allow you to turn on IR (infrared) communication
to communicate with an AutoRAE Lite.
Programming Mode is password-protected and includes adjustable settings to
accomplish the following:
•Calibrate the monitor (this includes zero and span, and changing the span gas
value).
•Change alarm limits.
•Change the monitor bump and calibration interval.
•Change the sensor configuration.
Diagnostic Mode is primarily intended for technicians to use during troubleshooting, although it
also offers access to a few changeable parameters that you may rarely (if ever) change. You can
enter Diagnostic Mode without restriction. In Diagnostic Mode, ToxiRAE 3 displays readings in
raw counts instead of units such as parts per million (ppm).
Page 11

ToxiRAE 3 User’s Guide
Parameters marked with an asterisk (*) can be adjusted by entering Programming Mode
from Diagnostic Mode. See Page 27 for details.
10.2. Normal Mode
Normal Mode is the default mode of the ToxiRAE 3 when it is turned on. By using the
[MODE] key, you can step through the screens that provide you with information from
the sensors, as well as the ToxiRAE 3’s current settings. The selected sub-mode (Display
or Disposable) determines the number of screens that are accessible.
10.2.1. Enter Normal Mode / Turn On The ToxiRAE 3
1. With the ToxiRAE 3 turned off, press and hold [MODE].
2. When the display turns on, release the key. The buzzer and LEDs are tested and the
display shows “On” followed by the firmware version (for example, F 1.0). It then
starts a countdown (the time is based on the sensor’s warmup requirements).
Note: If the ToxiRAE 3 detects a bad sensor, it aborts the countdown and gives this message:
If you see this error message, shut off the ToxiRAE 3 and contact your distributor or
RAE Systems technical support.
If the countdown proceeds and reaches 0, then the ToxiRAE 3 goes to one of two sub-
mode types: Display and Disposable.
10.2.2. Display And Disposable Sub-Modes
The factory default for the ToxiRAE 3 is to provide a ppm (parts per million) display.
However, using the AutoRAE Lite utility program, it is possible to set the ToxiRAE 3 to
use its Disposable sub-mode.
Display. This display tells you the current reading, in parts per million.
However, the display may alert you if a bump test or calibration is necessary:
Page 12

ToxiRAE 3 User’s Guide
•If the bump due day has passed, OK is not shown on the display. Instead “BUMP”
flashes.
•If the calibration due day has passed, OK is not shown, and instead “CAL” flashes.
If there are still days left until both bump testing and calibration are necessary, “OK” is
displayed.
Unless a bump test or calibration is necessary, the ToxiRAE 3 is ready to use. You can
proceed to perform a bump test, test the alarms, or view the STEL screen:
•To perform a bump test, press [MODE] repeatedly until you see “Bump” flashing in
the display.
•To test the buzzer, LED, and vibration alarms, momentarily press [Y/+].
•To advance to the STEL screen, press [MODE].
Disposable. This display tells you how many days until the ToxiRAE 3 expires. The
screen alternates between the word “dAy” and the number of days:
If the bump due day has passed, OK is not shown on the display. Instead “BUMP”
flashes once for a half-second.
If the calibration due day has passed, OK is not shown, and instead “CAL” flashes once
for a half-second.
If there are still days left until both bump testing and calibration are necessary, “OK” is
displayed.
•To perform a bump test, press [MODE] repeatedly until you see “BUMP” flashing.
Follow the instructions for bump testing on page 26.
•To test the buzzer, LED, and vibration alarms, momentarily press [Y/+].
•To advance to the STEL screen, press [MODE].
10.2.3. Exit Normal Mode / Turn Off The ToxiRAE 3
Whenever you turn off the ToxiRAE 3, it will start up in Normal Mode the next time it is
turned on, unless you intentionally place it in Diagnostic Mode. Follow the detailed instructions
on entering Programming Mode and Diagnostic Mode for information on entering the other
two modes.
Page 13

ToxiRAE 3 User’s Guide
Press and hold [MODE] while the ToxiRAE 3 goes through a countdown to 0. When it says “oFF,”
release your finger, and the ToxiRAE 3 is off. After it is shut off, the ToxiRAE 3 will automatically
be in Normal Mode the next time you start it.
10.2.4. Stepping Through Normal Mode (Display)
STEL Press [MODE] to advance to STEL. This provides Short Term Exposure Limit
(STEL) data. These are based on 15-minute STEL values of H2S and CO in
ppm. A STEL value is only displayed after the ToxiRAE 3 has been on for 15
minutes.
Note: If you do not press a key within 1 minute, the display reverts to the
normal reading.
TWA Press [MODE] to advance to TWA. The TWA (time-weighted average)
reading is the average reading of the gas concentration times the fraction of 8
hours that the monitor has been on.
Note: If you do not press a key within 1 minute, the display reverts to the
normal reading.
Peak Press [MODE] to advance to Peak (indicated by the letter “P” alternating with
a reading). This tells you the highest reading for each sensor since the
ToxiRAE 3 was turned on. Press [Y/+] twice to clear the Peak and Min or
[MODE] once to advance to Min.
Note: If you do not press a key within 1 minute, the display reverts to the
normal reading.
Alarms If there have been any alarms, you can step through them by pressing
[MODE], and reading up to 10 events, labeled A01 through A10, including
STEL, High, and Low alarms, and the readings stored with them. (If more
than 10 events are recorded, new ones overwrite the oldest ones. Events
cannot be cleared or selectively removed.)
Note: If you do not press a key within 1 minute, the display reverts to the
normal reading.
IR When the ToxiRAE 3 is placed in an AutoRAE Lite that is connected to a
computer running ProRAE Studio software, the ToxiRAE 3 can upload event
data and download revised firmware. It also allows automatic calibration and
bump testing in an AutoRAE Lite. See page 19 for details.

ToxiRAE 3 User’s Guide
10.2.8. Navigating Programming Mode
The following diagram shows Programming Mode’s five submenus and how to navigate
through them.
Note: Press [MODE] to navigate from one menu choice to the next and [Y/+] to make
selections.
Important! When editing settings in Programming Mode, if you do not press a key for
60 seconds, the ToxiRAE 3 automatically exits Programming Mode and reverts to
Normal Mode’s main screen.
The high and low alarm limits, as well as the points at which the STEL and TWA alarms
are triggered, can be modified in this set of menus. Setting these limits provides
extremely precise alarm thresholds.
During each measurement period, the gas concentration is compared with the
programmed alarm limits (gas concentration alarm limit settings: Low, High, TWA and
STEL). If the concentration exceeds any of the preset limits, the loud buzzer, red flashing
LEDs, and vibration alarm are activated immediately to warn of the alarm condition. In
addition, the ToxiRAE 3 alarms if the battery becomes weak or the sensor fails. When the
battery’s power becomes too low, the ToxiRAE 3 warns you and turns off automatically.
