The aim of the bump test is to make sure a gas monitor is working at its optimum by briefly exposing the unit to a known concentration of the target gas. The reading is compared to the actual quantity of gas present, as stated on the test gas cylinder, and if the detector goes into alarm within an acceptable range of the actual concentration, usually within 10%, then it is working safely. If the bump test results are not within the acceptable range, or it takes more than 30-40 seconds to alarm, the gas detector must not be used until a full calibration has been conducted.
Please remember, however frequently you bump test, this does not remove the need to have gas detectors inspected, calibrated and serviced periodically by a competent individual. Contact Jorgensen today to get more information about how we can provide for your calibration and testing needs.
