Bump Test
A Bump Test is a quick check to ensure that the sensor and alarms are working properly. It is
done with the same gas as is used for span calibration. Enter the
menu, start the gas flow,
then press the Left Key to start bump count-down (typically 45 seconds, but varies with sensor).
After count-down, the bump test result
or
is displayed.
To abort the bump test during count-down, press the Right Key and
is displayed.
Although a Bump Test is a recorded event in the datalog, the user can always do an unrecorded
bump check such as by breathing into an oxygen monitor just to verify that the sensor and alarms
are functioning.
