Calibration and Bump Testing
Gas detectors should be functionally tested regularly to ensure their
correct operation. This is referred to as bump testing.
To bump test a Zeta Gas Sense detector, fit the Calibration cap to the stainless
steel filter housing. Then take a test Cylinder with the appropriate gas type &
concentration. Fit the tube from the cylinder to the Calibration cap . Open the
regulator on the cylinder. Check that the reading on the detector rises and reaches
the level indicated on the cylinder (Within the specified tolerance range)
If a detector fails this bump test then it should be zero’s in clean air then
recalibrated using the calibration cap and the gas cylinder.

A range of cylinders are available for testing the Gas Sense detectors.
