Manual calibration
The calibration kit provided by ISC must be used (Ref. 6116291 female connector
/ wires / voltmeter connection files).
1. Remove the detector cover
2. Connect the cable (strand) to the circuit’s male connector
Zero the sensor
1. Ensure that the sensor is in clean air. If not, inject air into the sensor at a
flow rate of 1 L/M, then wait for voltmeter levels to stabilize (use the gas
injection device: bottle of synthetic air, calibration pipe, tube).
2. Adjust the zero with the potentiometer’s ZERO until the voltmeter reads 0
mV.
Sensitivity
1. Now inject the known gas (1 L/M) into the sensor. Wait for the voltmeter
signal to stabilize.
2. Adjust the sensitivity if necessary with the potentiometer “
SENS
” until the
signal value (in mV) corresponds to the amount of reference gas used.
Use the following formula to calculate the correct value for the signal.
3. Stop injecting gas (remove the calibration pipe from the sensor).
4. Wait for the voltmeter to “return to zero.”
