WIKA operating instructions differential 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
Trouble shooting
