Bump Test Interval
At this screen, the user has the option to set the
desired frequency of the bump test before the
overdue alarm is activated. This default value is
one day and may be set in ½ day increments
from ½ day up to 7 days. This will allow the
user to ensure that instruments are bump tested
twice daily or before two shifts if desired. When
the set value has been exceeded without a
successful bump test occurring, the overdue
alarm described above will be activated.

Bump Test Timeout
This screen allows the user to set the desired length
of time for the bump test to take place before
failure. The default value of 45 seconds is used
and indicates that the instrument will determine
that the bump test has failed if a 50% response to
the calibration gas concentration is not reached
within 45 seconds. This value may be selected in 5
second intervals from 30 seconds to 300 seconds.
The bump test period will end when the selected
timeout value is reached regardless of whether the test has passed or failed.
