a) Attach the calibration adapter to the threaded sensor housing. Apply the test gas at a controlled flow rate

of 200 - 500cc/min (200cc/min is the recommended flow). Allow 1-2 minutes for the reading to stabilize.

Observe that during the 1-2 minutes the display increases to a level near that of the applied calibration gas

value.

b) Remove test gas and observe that the display decreases to “0”.

Initial operational tests are complete. Detcon combustible gas sensors are factory calibrated prior to shipment,

calibration test and adjustment be performed 16 to 24 hours after power-up. Refer to span calibration

instructions in Section 3.4.
