13.5.2. Gas Testing
To verify monitor operation, gas testing is
recommended. This ensures the integrity of the
sample tubing is still intact and the sensor is respond-
ing to gas. Gas testing can be done either by “bump
testing” or by performing a gas verification test.
A bump test is done by exposing each zone to
either a liquid or gaseous refrigerant. The test verifies
the sample path and checks that the sensor is
responding to gas. The refrigerant concentration is not
determined.
A gas verification test is done by exposing each zone
to a known concentration of gas and verifying that the
display readings are within 10% of the applied gas.
Gas verification kits for a variety of refrigerant types
are available which contain certified PPM
levels of test gas. For more information about gas
verification test, refer to Section 14.1.1., Testing with
Gas Verification Kit.
