Starting/Monitoring a Calibration: An Example
This section provides an example of how to initiate and then monitor a calibration.
1. Check that no calibration or verification is currently occurring by checking the
Calflag variable table (Calflag=3).
2. Send the Calibrate command to the Series 2000 control unit over the serial port
(GO).
3. If an acknowledge is returned (A<cr>), the calibration command is accepted. If
not accepted, the sensor may not be at a proper operating temperature or may
already be performing a system calibration.
4. Read the Gas_ctr variable to determine the position in the calibration cycle.
Use this variable to determine when to activate solenoids (if not controlling
solenoids using the Series 2000 control unit).
5. Read the Calflag variable to determine when the cal cycle is finished (Calflag=3).
6. Read the calibration values (for example, wet_cal_span and wet_cal_zero vari-
ables).
