5.1 Checking Channel Response to Gas

The TDX system is supplied precalibrated. After initial installation, the sensor should be checked with calibration/test

gas to confirm gas response. This test should be performed periodically (once every 3 – 4 months).

To check if the sensor requires calibration, introduce an appropriate calibration gas (gas of known concentration) to the

sensor. If there is a discrepancy of more than 10% between the voltage reading on the transmitter and the known

concentration of the gas, then the transmitter should be recalibrated.
