cGas Detector Analog Transmitter - Operation Manual
Rev. B | 2020.07
9.1.5 Gas Testing Frequency (Bump Testing)
For the purpose of safety in OHS applications, sensors should be gas tested
(bump tested) once every month to confirm response and alarm activation.
9.2 Calibrating the Internal Sensor(s)
Calibration has three processes - Set Calibration Gas Value, Span and Zero. The
Span and Zero calibrations can be done in any order.
9.2.1 Set Calibration Gas Value
Check to make sure that the calibration gas value configured in the device
matches the gas concentration of the calibration gas cylinder you are using.
This is especially important if you are not using the same Cal gas concentration
that was used previously to calibrate the device. How much gas the sensor
detects is directly related to the Cal gas setting and the actual concentration of
calibration gas used during calibration.
