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.
Figure 1 shows the location of the different display fields, while are described in the
following table.
