Turn off Gas!
Turn off the gas flow and disconnect the calibration adapter from the
monitor. If calibration fails, an error message appears instead.
Refer to
Troubleshooting: “Calibration Error Message” on page 38.
NOTE:
If calibration is accidentally started and gas has run out or has
been disconnected, press
M
repeatedly. Calibration will stop and revert
back to the previous calibration values.
Calibrating the PID Sensor
The single sensor method used to calibrate the PID can also be used to
calibrate single toxic sensors. For the PID, use isobutylene (100ppm)
span gas. For other toxic sensors, use the appropriate gas, e.g.,
ammonia sensor - use ammonia gas, etc.

The 60-second countdown timer appears.
“Span Cal Done! Turn Off Gas” message
appears. The readings should be very close
to the span gas values shown on the gas
cylinder.
