11. Operating The ToxiRAE Pro CO2
11.1. Overview
The ToxiRAE Pro CO
2
has two operational modes:
•
Normal
— see page 15 for detailed instructions.
•
Diagnostic
— see page 48 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
CO
2
. 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 CO
2
displays readings in raw counts instead of units such as parts per million (ppm).
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 CO
2
when it is turned on. The
selected sub-mode (Basic or Advanced) determines the number of screens that are
accessible.
