AUTO BUMP / CAL STATION - HANDBOOK
The Auto Bump / Calibration Station can be used for:
• A ‘Quick’ Bump Test, approximately 15 seconds gas
duration, to verify that the instrument alarms will activate
when the alarm setpoints are reached.
• A ‘Full’ Bump Test (factory default), approximately 60
seconds gas duration, performs a full Bump Test of alarm
setpoints and sensor response. This is followed up with
an automatic calibration of failed gas ranges, if applicable.
• A Full Calibration of the instrument, approximately 60
seconds gas duration.
The unit can be free standing on a workbench, or alternatively,
secured to the workbench individually or in daisy chain fashion
using the mounting bracket and screws supplied with the unit.
Refer to APPENDIX-A for tting instructions.
Power is supplied to the rear of the unit via a 12V Universal
Power Supply Unit (PSU) supplied with the unit. A 12V Vehicle
Power Supply is available as an accessory.
Gas is connected to the clearly marked inlet adaptor at the
rear of the unit. An integral pump automatically draws gas into
the instrument for bump / calibration operation.
The user simply inserts the PS200 instrument to be tested
into the Auto Bump / Calibration Station, then closes the cover
initiating the automatic testing process.
The Auto Bump / Calibration Station uses a trafc light system
to display progress / result and thus provides the user with
a clear indication of whether the PS200 meets selected
parameters.
i.e. LED 1 (Green) = ON (power)
LED 2 (Orange) = TEST (in progress)
LED 3 (Green) = PASS
LED 4 (Red) = FAIL
