MANUAL BUMP TEST
MANUAL BUMP TEST
3.1 BACKGROUND
A bump test verifies sensor response and alarm operation
by exposing the instrument to a known concentration of
gas. The PS200 series of instruments can be bump tested
either manually or automatically (using the Auto Bump /
Calibration Station) .
This chapter details how instruments can be manually
bump tested to ensure the readings provided are accurate
and provide the user with immediate warning of a
potentially hazardous situation.
To facilitate manual bump testing, a test kit (Part No. 64121)
is available and contains the necessary test gas, regulator
and Tygon
®
tubing to ensure a proper bump test is
performed.
CAUTION: When performing a bump test, the
test gas concentration should be high
enough to trigger the instrument’s
alarms. Should any instrument fail a
bump test, then a full calibration must
be performed.
