9. Press the Enter key once the combustibles span gas reading(s) stabi-

lize on the far left of the display.

Then, if you specified a recovery time, the system will display the recov-
ery time remaining:

Recovery xx:xx

System Calibrating

The system then returns to monitoring process readings.

Be sure to reinsert the 1/4" tube cap on the calibration inlet port on
the sensor once you have completed the manual calibration. This
prevents air from getting into the sample gas line during normal
operations.
