4.5 Bump test
(or "functional test")
Bump testing is a functional test in which an instrument's installed
sensors are to be briefly exposed to (or “bumped” by) calibration
gases in concentrations that are greater than the sensors’ low
-
alarm setpoints. This will cause the instrument to go into low
alarm and will indicate which sensors pass or fail this basic test
for response to gas.
Note:If fails the bump test, please perform a calibration. If failes
the calibration, please contact Industrial Sicentific after-sales
service.
