85 • Calibrating a Gas Tracer
27. After the fresh air purge is complete, the screen will alternate between the gas
readings and the calibration results. The calibration results are indicated with a
P (pass) or an F (fail) to the left of the channel units. If the calibration passed,
the auto calibration values will be displayed. If the calibration failed, the gas
readings at the end of the gas application will be displayed. Use the EDIT
ENTER button to scroll between the calibration results for the standard three
sensors and the calibration results for the ppm sensor and %volume sensor (if
installed). The CAL
S
LED will stop blinking and be steadily green if all
channels passed the calibration or steadily red if any channel failed the
calibration. In the example below, both the CO and ppm sensors failed the
calibration.
