Absolute-pressure measuring ranges <1 bar absolute are, by definion, in an overload condion
at atmospheric pressure.
5.2 Tighng the pressure port (depends on the pressure range of the instrument
5.3 Preliminary checks
Be sure that pressure provided is not higher than the instruments full scale value. Mount the
instrument as suggested. If the device is installed in a calibraon circuit, please perform a
bleeding before starng to work.
5.4 Switch on the instrument
When switched on, the instrument performs a self-test (about 3 seconds), showing
the firmware version and the full scale value of the instrument.
Aer this test, the measured pressure is displayed.
5.5 Error messages
UUUUU
Overpressure. A pressure above the instrument‘s full scale value is applied.
Immediately reduce the applied pressure!
Instrument‘s calibraon may become invalid if a too high pressure is applied.
LLLLL
Negave scale overflow. A pressure below the instrument‘s start value is applied.
Immediately increase the applied pressure!
HHHHH
If pressure unit is changed, and the present pressure value cannot be displayed
due to display resoluon limitaons (max. 99999). Change pressure unit to another
one.
Too low ba ery level. Indicated pressure values are not reproducable or might be
wrong. Charge ba ery immediately.
Ba ery is fully charged.
