LCD Contrast
The display’s contrast can be increased or decreased from its default setting. You may
not need to ever change the default setting, but sometimes you can optimize the display to
suit extreme temperature and ambient brightness/darkness conditions.
1.
Press and hold [Y/+] to select a desired level of contrast. The range is 1 to 100.
Once 100 is reached, pressing [Y/+] again "wraps" around back to 1.
2.
When you have completed your selection, press [MODE] repeatedly until “OK” is
highlighted.
3.
Press [Y/+] to save your selection, and exit the LCD Contrast
.
Note:
If you do not want to save the change, press [MODE] repeatedly until
“Cancel” is highlighted. Press [Y/+] to exit without saving the changes.
Exit (Monitor Setup Submenu)
Press [Y/+] to exit. Monitor Setup is exited. Exit (to exit Programming Mode) is
highlighted.
11.6. Exit (Exit Programming Mode)
To exit Programming Mode and return to normal operation, press [MODE] until the Exit
icon is highlighted. Press [Y/+] to exit. You will see “Update Settings…” as changes are
registered and the mode changes to normal operation.
12. Policy Enforcement
The ToxiRAE Pro CO
2
can be configured to enforce a facility/company’s requirements
that calibration and/or bump testing be performed at specified intervals, and to warn the
user that calibration/bump testing is required. In addition, it can require calibration or
bump testing and not allow normal operation of the instrument unless calibration or bump
testing is performed.
If Policy Enforcement is enabled and if the instrument has been bump tested and
calibrated in compliance with the policy settings, a check-mark icon is included along the
top of the ToxiRAE Pro CO
2
screen:
If Policy Enforcement is enabled, then after startup the ToxiRAE Pro CO
2
displays a
screen that informs the user that the instrument requires either a bump test or a
calibration. If both are required, then they are shown in sequence.
12.1. Setting Policy Enforcement
You must use ProRAE Studio II to make changes to Policy Enforcement settings. The
procedure differs, depending on whether you are using an AutoRAE 2 Cradle, a
ToxiRAE Pro CO
2
Travel Charger, or a ToxiRAE Pro CO
2
Desktop Cradle.
