6. Commissioning, operation

As soon as the hand-held pressure 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. The pressure indication of the calibrator should be zeroed before starting the

pressure calibration.

6.1 Calibrator display

The calibrator's display consists of two sectors: The menu bar (located along the

bottom of the screen) is used to access the menu system. The main display (the rest of

the display) consists of up to three sub-sectors for the measurement activities. These

sub-sectors will be referred to as the UPPER, MIDDLE and LOWER displays in this

document.
