Configure Verify
The Configure Verify menu option allows you to define the verify gas
value and the acceptable range of readings for a verify.
To set your verify gas value and acceptable verify range, do the following:
1. Select Configure Verify from the Calibrate Key menu.
2. Select whether you wish to enter the verify gas using a percent or
PPM scale.
You will be prompted to enter the verify gas value:
Verify Gas = xx O2
New Value?
3. Enter the verify gas value, then press the Enter key. If you wish to
keep the current verify gas value unchanged, press the Enter key
without entering a value.
4. Enter the acceptable verify range. For example, if you enter a verify
gas range of 1%, and the verify gas value is 10%, then the acceptable
range is between 11% and 9%.
If during a verify operation (Initiate Verify menu option) the system
finds that the verify gas is not within the acceptable range, a Verify
Failure message will appear on the bottom line of the display, and
the Service Alarm will trip. The error message will continue to be
displayed until a successful verify is completed (gas value within the
range) or a successful calibration is completed.
