6 Commissioning, operation
As soon as the calibrator is turned on, by pressing the ON/OFF key, it will go through a short self-
test routine. During that routine, the display shows the current firmware version, auto-shutdown
status and the range of the internal pressure sensor. The calibrator requires a maximum of 5
minutes warm-up to reach its specified accuracy. Large changes in ambient temperature may
make a longer warm-up period necessary. Pressure ranges should be zeroed each time the
calibrator is started.
