6. Click on the Defaults button to display the default values for cali-
bration gas, high and low alarm setpoint, and update rate. If other
values are desired, enter them in the appropriate boxes.
When a K Factor is Used
If the sensor is calibrated using a gas type that is different than the
gas being detected, a calibration “K factor” must be used. (Refer to
Det-Tronics Technical Note No. GTN01 for complete information
regarding the use of K factors.)
If a K factor is used for sensor calibration, a similar adjustment
should be made when entering the calibration gas value at the OIS.
Use the following formula to determine the correct value to be
entered in the box labeled “Now” under Cal. Range. This will
ensure the most accurate gas level reading at the OIS.
C x K = S
C = Concentration of calibration gas in % LFL
K = K factor for the gas to be monitored (from Table 1 in GTN01)
S = Corrected calibration output level
(Enter this value in the box labeled “Now” under Cal. Range).
