ToxiRAE Pro LEL User’s Guide
11. Operating The ToxiRAE Pro LEL
11.1. Overview
The ToxiRAE Pro LEL has two operational modes:
Normal — see page 16 for detailed instructions.
Diagnostic — see page 49 for detailed instructions.
The following is an overview of the two modes:
Normal Mode is the default mode. It is accessed when you turn on the ToxiRAE Pro
LEL. Two sub-modes are available: Basic User and Advanced User. In Basic User, some
restrictions are applied, including password protection that guards against entering
Programming Mode by unauthorized personnel. In Advanced, there are no such access
restrictions (you do not need a password), and it provides the indications and data you
need most for typical monitoring applications.
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) need to change. A
password is required to enter Diagnostic Mode (the password is the same as (and
automatically kept in sync with) the one used to enter Programming Mode). The default
password is 0000. To enter Diagnostic Mode, power the instrument off and then turn it
back on by pressing and holding both the buttons. In Diagnostic Mode, ToxiRAE Pro LEL
displays readings in raw counts instead of units such as %LEL.
It is not possible to switch to Programming from Diagnostic Mode without turning off the
instrument first and then restarting it in the desired mode.
11.1.1. Normal Mode
Normal Mode is the default mode of the ToxiRAE Pro LEL when it is turned on. The
selected sub-mode (Basic or Advanced) determines the number of screens that are
accessible.

password.
To exit Programming Menu and return to the measurement screen (in Advanced User
mode), press the [MODE] button repeatedly to highlight the Exit icon in Programming
Menu and press [Y/+] to exit to the measurement screen.
When the ToxiRAE Pro LEL is in Advanced User mode, pressing [MODE] steps through
the same screens, but with the addition of a screen that allows for selection of different
measurement gases from the internal library. Also, once in Advanced User mode, you
may enter Programming without using a password.
Note: In Advanced User Mode, you may select different measurement gases from the
internal library.
Note: The gray box indicates the datalog functions when datalogging is in Manual mode.
When datalogging is in Automatic mode, these screens do not appear. Refer to page 27
for information on selecting Automatic or Manual datalogging.
11.2. Navigation In Normal Mode
Step through the screens in Normal Mode by pressing [MODE]. Some screens allow
actions on your part, such as clearing the data. In these instances, pressing [Y/+] performs
the action.
