AUTO BUMP / CAL STATION - HANDBOOK
On completion, the gas values (except oxygen) return to
zero, then the instrument initiates a countdown sequence
and switches OFF.
A ‘PASS’ is indicated by a green LED, as illustrated in Fig. 4-12.

Alternatively, a ‘FAIL’ is indicated by a red LED, as illustrated
in Fig. 4-13.
Fig. 4-13 FAIL Indication
Note: If the instrument fails, please ensure you are
using the correct gas cylinder and the cylinder
contains enough gas to perform a bump /
calibration. The pressure gauge on the Regulator
Valve gives a clear indication of this.
Next, the station pump switches OFF and the instrument can
be safely removed from the Auto Bump / Cal Station.
The test result indication is displayed until the instrument is
removed from the Auto Bump / Cal Station.
All test results are stored in the Auto Bump / Calibration
Station memory and can be accessed as detailed in Chapter
5 of this handbook.
