Notes

B

ump testing a gas
sensor involves
flowing a concentration of gas that
is slightly higher
than the low alarm
setpoint of the gas
detector for a short period of time
(one to two minutes or less). The purpose of a bump test is to confirm that
the sensor responds to the presence
of gas, the low alarm will activate and
the gas detector overall is operating
appropriately. The bump test is used
to confirm that your life saving gas
alarm device is working correctly.
A bump test does not measure the
accuracy of the sensors or its state
of calibration.
Electrochemical toxic gas sensors
tend to output "0" in clean air and
"0" when they have expired so it is
important to bump test a sensor for
critical applications to ensure the sensor has not expired. If at any time the
NH3 sensor has been exposed to an
undetermined amount of NH3 a bump
test should be performed.

Keep a Log

Notes:
When using 300 ppm, response should be within 15 to 30 seconds; 100 ppm, within 1 min; 50 ppm, within 2 min.
Make mental note of the reading and the length of time and remove the gas as soon as alarm responds. Record the results.

An important part of the bump
test process is keeping a record of
the readings. A consistent bump test
schedule with recorded results can
help you monitor the overall health
of the sensor and the gas detection
system in general. It can alert you to
inconsistencies which may indicate
that the detector is not performing
