6. Commissioning, operation
As soon as the model CPH65I0 hand-held pressure calibrator is turned on, by pressing
the ON/OFF key, it will go through a short self-test routine. During this routine, the
display shows the current firmware version, auto-shutdown status and the measuring
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 display of the calibrator should
be zeroed before starting the pressure calibration. See chapter 6.3 "Use of the "ZERO"
function".

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, which are described in the
following table.
