MANUAL BUMP TEST OPTIONS
MANUAL BUMP TEST OPTIONS
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 describes the manual bump test options
that validate either the alarm operation (quick bump), or
both alarm operation and sensor response (full bump).
By default, both of these options are disabled.
To facilitate manual bump testing, a test kit (Part No.
64051) 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.
A Quick bump test only checks the
operation of the audible and visual
alarms and does not validate sensor
accuracy or response time.
