Failure Possible cause
No/incorrect voltage supply or current
No output signal
spike
Cable break
Incorrectly wired (e.g. Connected as
No/False output signal
2-wire instead of 3-wire system)
Abnormal output signal Span incorrectly adjusted
Zero point set wrongly
Output signal unchanged after change Mechanical overload through over-
in pressure pressure
Wrong supply voltage or current spike
Signal span too small Power supply too high/too low
Signal span drops off Moisture present (e.g. at the cable tail) Install the cable correctly
Electromagnetic interference source in
Signal span erratic
the vicinity, e.g. inverter drive
Instrument not grounded
Strong fluctuations in the power supply
