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 submode 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.
Page 12
ToxiRAE 3 User’s Guide
However, the display may alert you if a bump test or calibration is necessary:
•
•
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/+].

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
Page 13
ToxiRAE 3 User’s Guide
on entering Programming Mode and Diagnostic Mode for information on entering the other
two modes.
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

Note: If you enter an incorrect number while trying to enter Programming Mode from
Diagnostic Mode, the ToxiRAE 3 exits to Diagnostic Mode’s main screen instead of
Normal Mode’s main screen.
Note: The password can only be changed by using AutoRAE Lite software on a PC.
If you change the password, write it down and save it in a safe location.
Page 17
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.
Page 18
ToxiRAE 3 User’s Guide
11. Bump Testing & Calibrating The ToxiRAE 3
RAE Systems recommends that a bump test be performed periodically on the ToxiRAE
3. The monitor should be calibrated if it does not pass a bump test, but no less than every
6 months, depending on use and exposure to gas and contamination, and its operational
mode.
A bump test is defined as a brief exposure of the monitor to the calibration gas and
the sensors to show response and trigger the lowest alarm set point for each sensor.
•
Calibration intervals and bump test procedures may vary due to national
legislation.
Note: Bump testing and calibration can also be performed by using the RAE Systems
AutoRAE Lite™ docking station. Instructions are provided with it.
Note: After a bump test is performed and the ToxiRAE 3 passes, the ToxiRAE 3 resets
its countdown until the next bump test is required to the maximum number programmed
in its memory.
11.1. Bump Testing & Calibrating With An AutoRAE Lite
Bump testing and calibrating a ToxiRAE 3 with an AutoRAE Lite docking station
requires that the ToxiRAE 3 be placed in IR (infrared mode) before it is placed in the
AutoRAE Lite’s cradle.
1. Make sure the ToxiRAE 3 is on and in monitoring mode.
2. Press and hold [Y/+] for 3 seconds. When “Ir” appears, release the key.
3. Place the ToxiRAE 3 in the AutoRAE Lite’s cradle and begin a bump test or
calibration.
Note: Follow all instructions in the AutoRAE Lite User’s Guide for successful
calibration.
Page 19
ToxiRAE 3 User’s Guide
11.2. Calibration Adapter
The ToxiRAE 3 is a diffusion monitor and must be calibrated using a fixed-flow
regulator with a flow rate between 0.5 and 1.0 liters per minute. The ToxiRAE 3 is
supplied with a special calibration adapter that covers the gas diffusion port. If the local
air has impurities that might interfere with zero (fresh air) calibration, the calibration
adapter and a cylinder of clean zero air should be used.
11.2.1. Connecting The Calibration Adapter
1. Attach the Calibration Adapter over the inlet port on the front of the ToxiRAE 3
by pressing it into place.
2. Attach the hose from the regulator/calibration gas cylinder to the Calibration
Adapter’s inlet.
Caution! After calibration is complete, remove the Calibration Adapter. When
monitoring, never operate the ToxiRAE 3 with the Calibration Adapter attached. The
ToxiRAE 3’s sensor operates by diffusion. If the Calibration Adapter is attached during
normal operation, inconsistent and lower-than-normal readings will occur because of
decreased concentration of the gas being monitored.
Page 20
ToxiRAE 3 User’s Guide
11.2.2. Disconnecting The Calibration Adapter
After calibrating the ToxiRAE 3, you must remove the Calibration Adapter. Lift the
Calibration Adapter from the ToxiRAE 3 and store it.
11.2.3. Calibrations And Settings In Programming Mode
Turn on the ToxiRAE 3. Once it has been through its startup, enter Programming Mode:
1. Press and hold both [MODE] and [Y/+] until you see the password screen, “000.”
2. Enter the password (the default is 111) by pressing [Y/+] to increase the number,
followed by pressing [MODE] to advance to the second digit. Follow this
procedure until there are three “1”s.
3. Press and hold [MODE] until you see the “Zero Cal?” screen.
The ToxiRAE 3 is now ready for zero calibration.
Note: If the ToxiRAE 3 is in Programming Mode and you do not press a key within 60
seconds, it exits Programming Mode and re-enters Normal Mode.
11.2.4. Zero (Fresh Air) Calibration
This sets the zero point of the sensor calibration curve for clean air. Expose the ToxiRAE
3 to a clean air source with 20.9% oxygen and without any organic, toxic or combustible
gas impurities. This “Zero Air” can be from a cylinder, clean ambient air, or ambient air
purified through a charcoal filter.
Note: If you use a zero air cylinder, you must use the ToxiRAE 3 Calibration Adapter.
With the ToxiRAE 3 on and in Programming Mode, follow this procedure:
1. Press [Y/+]. A countdown starts and “CAL” blinks. This indicates that zero
calibration is taking place.
2. When the countdown reaches “0,” the display alternates between “0” and “dn”
(for “done”).
Upon completing a zero calibration, the ToxiRAE 3 automatically advances to the span
calibration menu.

performed.
Important! If you used the Calibration Adapter and a zero air cylinder, you must remove
the Calibration Adapter from the ToxiRAE 3. If the Calibration Adapter is attached
during normal operation, inconsistent and lower-than-normal readings will occur because
of decreased concentration of the gas being monitored.
11.2.5. Span Calibration
This procedure determines the second point of the sensor calibration curve for the sensor.
Performing a Span Calibration requires using the Calibration Adapter, a flow regulator,
and a tank of span gas.
Before starting a span calibration, connect the gas cylinder, flow regulator, and
Calibration Adapter to the ToxiRAE 3 and start the gas flow.
With the ToxiRAE 3 on and Programming Mode, and with the Span Cal menu screen
showing, follow this procedure:
1. Press [Y/+]. A countdown starts and “CAL” blinks. This indicates that span
calibration is taking place.
