Set K-Factors
This menu option allows you to enter K-Factor (Correction Factor) to
match the indications obtained from the combustible sensor with gas
flowing through the cal port to those obtained when the same gas flows
through the inlet probe. Note that care must be taken when applying
gas to the inlet port to assure that is does not change the flow from that
generated by the aspirator. This factor was determined at the factory
and documented on the front pages of the instruction manual. It should
not need changed unless the sensor control board was replaced or the
EEPROM is cleared. The default factor of 1.00 is set on a new control
board or after the EEPROM is erased. The factor must be re-entered to
assure accuracy. The factor is adjusted by pressing the CALIB key and
scroll down to the "ENTER K-Factors" by using the down arrow key.
