Bump Test
The bump test screen allows the user to
initiate and perform a manual bump test of
the instrument using calibration gas. (This
screen will only be seen if the bump test
option is enabled in the configuration mode.)
After initiating the bump test by pressing the
Enter button at this screen, the user will
apply the calibration gas to the instrument as
described previously under Calibration.
Actions Available from the Bump Test Screen

Go to Gas Monitoring screen.
If the sensor responds to 50% of the
calibration gas value within the timeout
specified in the configuration mode the
instrument will pass the bump test.
If not, the instrument will fail the bump test
and a bump fault screen ("bF") will display as
shown here. The instrument is placed in
periodic alarm until it passes a bump test.
If the bump overdue alarm is enabled in the
configuration mode, this screen will appear on
the instrument and remain until a bump test of
the instrument is completed successfully.
