WIKA operating instructions dierential pressure gauge models 712.15.100, 732.15.100

Defect Possible reason Remedy

No signal output

Failure of power supply Check power supply and wiring

Wiring interrupted (or broken) replace defective components

Transmitter incorrectly wired Check wiring;

if necessary rectify it

No pressure Check tailpipes

Open press. compensation valve

Close pressure compensation valve

Electronic defect e.g. through Return pressure gauge to

incorrect supply voltage manufacturer for repair

or stray voltage spikes

Steady signal Pressure entry blocked Check tailpipes and pressure entry

despite pressure bore, if necessary clean it carefully

variation Open press. compensation valve Close pressure compensation valve

Electronic defect e.g. through Return pressure gauge to

incorrect supply voltage manufacturer for repair

or stray voltage spikes

Transmitter defect after being Return pressure gauge to

over-pressured manufacturer for repair

Steady and too high Electronic defect through Return pressure gauge to

signal despite of incorrect supply voltage manufacturer for repair

pressure variation or stray voltage spikes

Full span reading too low Supply voltage too low Adjust supply voltage

Load impedance too high Consider permissible max. load

Wrong scale selected Check position of scale selection

switch

Zero signal too low Wrong zero compensation Readjust zero point

Zero signal too high Wrong zero compensation Readjust zero point

Transmitter over-pressured Return pressure gauge to

manufacturer for repair

8. Transmitter for level measurement
