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.
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.
