Bump Test
WARNING!
Perform a Bump Test before each day's use to verify proper device operation.
Failure to perform this test can result in serious personal injury or death.
NOTE: Bump test frequency is often stipulated by national or corporate regulations; however, bump testing before each
day's use is generally the accepted best safety practice and is therefore MSA's recommendation.
This test quickly confirms that the gas sensors are functioning. Perform a full calibration periodically to ensure accuracy
and immediately if the device fails the Bump Test. The Bump Test can be performed using the procedure below or
automatically using the GALAXY or GALAXY GX2 Test Stand.
CSA requires (per 22.2 NO. 152) that combustible sensor sensitivity be tested before each day's use on a known
concentration of methane equivalent to 25 to 50 % of full scale concentration. ACCURACY MUST BE WITHIN 0 to +20 %
OF ACTUAL. Correct accuracy by performing the calibration procedure described in
NOTE: The Automated Test Stands cannot test the following sensors:

% Vol Propane
% Vol Methane
For these sensors, use this Bump Test procedure.
