initiate Cal
Perform an automatic, remote, or manual calibration.
The Auto Calibrate and Remote Calibrate selections are only available if you
have installed an Auto Calibrate card in the control unit and have a Remote Cali-
bration Unit (RCU). If the control unit detects that these options are not installed, it
will automatically prompt you with a manual calibration operation when you select
the Initiate Cal menu option.
Automatic calibrations can also be set to run at predetermined frequencies using
the cycle times defined using the Set Cal Timers/Set Auto Timers menu option.
Once you’ve set these cycle times, you don’t have to select the Initiate Cal menu
option to run an automatic calibration.
When using a digital input to trigger the auto calibration, make sure that the
Setup Key/Remote Switch Config selection is set to calibrate , and not verify.
If you replaced a cell, or your cell has failed a regular calibration
because of a deterioration, you will need to perform a primary cali -
bration rather than a regular calibration. See the Primary Calibra-
tion section in Setup Key Chapter 4 for help.
See Chapter 3 for calibration gas requirements.
If you selected Two-Gas Cal on the Setup Key menu, skip to the
instruction for performing a two-gas calibration on Page 5-18.
