Commissioning

When the calibrator is turned on by pressing the ON/OFF key, it will go through a
short startup self-check routine. During that routine, the display shows the current
firmware revision level, auto shutdown status and the ranges of the internal pressure
sensors. The calibrator requires a maximum of 5 minutes warm-up to rated
accuracy. Large changes in ambient temperature may require a longer warm-up
period. See chapter 6.4 for instructions on zeroing the pressure sensor displays.
Pressure ranges should be zeroed each time the calibrator is started.

Calibrator display

The calibrator display consists of two regions: The menu bar (located along the bottom of the
screen) is used to access a menu system. The main display (the rest) consists of up to three
process measurement sub-regions. These sub-regions will henceforth be referred to as the
UPPER, MIDDLE and LOWER displays. The following figure and table show the location of the
different display fields and a description.
1) Primary parameters
Indication of the current measured parameter
2) Display of the span
Indication of the 4 ... 20 mA span (only for the mA measurement)
3) Pressure units
Indication of the pressure unit (selectable from 17 pressure units)
4) Units
Indication of the measurement unit
5) Menu bar
