Bump Test
Bump test is a procedure that confirms a detector’s ability to respond to target gases by exposing
the detector to gas concentrations that exceed its alarm setpoints. Perform bump tests regularly
to confirm that sensors are responding correctly to gas, and that audible, visual, and vibration
alarms activate during an alarm condition.
If Force Bump Test is enabled, you may be prompted to bump test during startup. For more
information, see User Options and Settings, or consult the ImpactXtreme Technical Reference
Guide.
BW Technologies by Honeywell recommends that you
1) Bump test the detector before each use.
2) Calibrate the detector if readings are not within specified limits.
BW Technologies by Honeywell recommends to bump test the sensors before each
day’s use to confirm their ability to respond to gas by exposing the sensors to a gas
concentration that exceeds the alarm setpoints.
Bump test only in a normal atmosphere (20.9% O
2
) that is free of hazardous gas. Do not
bump test in a hazardous area.
The maximum tubing length for calibration is 1m (3 ft).
Before you begin
1) Have ready the calibration adapter and calibration tubing cut to a maximum 1.0 metre (3
foot) length.
2) Use premium-grade calibration gases.
3) Use gases approved by the National Institute of Standards and Technology, or equivalent.
4) Do not use gas cylinders past their expiration date.
5) Verify that the gas you intend to use matches the span concentration values set for the
monitor.
