a. Since calibration gas has already been flowing to the PID sensor while the other
channels were being calibrated, the PID sensor reading should be stable and

b. Press and release the POWER/ENTER button to set the span adjustment for the
PID channel to the programmed value. Continue with Step 30.
30 . If the PID channel passed calibration, the following screen sequence occurs.
If the PID channel cannot be adjusted to the proper value, a screen displays that
indicates a calibration failure and indicates that the PID sensor failed to calibrate.
The buzzer and alarm LEDs activate in a double pulsing pattern. Press and release
the RESET button to reset the alarm and continue to the Auto Cal Menu. Attempt to
calibrate the PID channel again. If the failure continues, investigate the cause. See
“Troubleshooting” on page 100.
