test. The available choices are 30 seconds (factory setting), 45 seconds, 60 seconds, and
90 seconds.

Updating the CHECK Setting
The
CHECK
is the bump test tolerance value and is represented as a percentage. It is the
percentage that the bump test reading can differ from the actual gas concentration. If the
bump test reading differs more, the bump test will fail. The available values are 10%, 20%
30% (factory setting), 40%, and 50%.

Updating the CAL TIME Setting
The
CAL TIME
is the total time the instrument is exposed to calibration gas when a
bump test fails if
AUTO CAL
is set to
ON
. The bump test time is deducted from the
calibration time. For example, if the
CAL TIME
is set to 90 seconds and the
GAS TIME
is set to 30 seconds, if the bump test fails, the GX-6000 will only be exposed to gas for an
additional 60 seconds. The available values are 90 seconds (factory setting), and 120
seconds.
