Updating the Calibration Check Setting
This item setting defines which sensors are used to update the
calibration reminder screen. C--CHECK can be set to 4-GAS or ALL. If
C--CHECK
is set to 4-GAS, the calibration dates for only the standard
sensors (LEL, O
2
, and CO) are used to determine if calibration is due.
If C--CHECK is set to ALL (factory setting), the calibration dates for
the standard sensors along with the %volume sensor and the ppm
combustible gas sensor are used to determine if a calibration is due.
Since the Gas Tracer only has a ppm sensor, C--CHECK must be set to
ALL.
1. Use the AIRS or (SHIFT)T buttons to display the C--CHECK
menu item. Press and release the POWER ENTER button. The
screen will indicate the current setting.
2. Use the AIRS or (SHIFT)T button to display ALL.
