5. Apply the appropriate level of calibration gas from the calibration
equipment to the instrument’s GAS or BACKGROUND inlet port. (In
the example above, apply 2.5% CH
4
to the BACKGROUND port.) Then
press the I/Okey to start the calibration process. Observe that the
gas-sampling-pump motors start and the calibration screen appears.

6. If necessary, use the keys to adjust the Appl(%) reading to match
the gas concentration stamped on the calibration gas cylinder.
7. Wait until the measured gas reading stabilizes, and then press the
I/O
key to calibrate the actual gas reading to that of the applied
reading. The message “Calibration Passed!” will appear at the bottom
of the screen if the calibration was successful. If, however, the

8. Disconnect the gas hose, and then wait until the measured gas
reading falls to zero percent.
9. Press the ESC key to return to the Calibration Menu Screen.
