Problem Possible cause
No output Power supply failure
Open wiring
Wiring reversed
No pressure or port blocked
Transmitter failure due to wrong
Supply voltage or power surge
Output steady as pressure Pressure port blocked
changes Transmitter over-pressurized
Transmitter failure due to wrong
supply voltage or power surge
Full span output low Supply voltage too low
Load impedance too high or too low
Transmitter over-pressurized
Zero signal too low or too high Transmitter over-pressurized
Non-linear output Transmitter over-pressurized
*) Test the system for proper operation after adjustments are made. An excessive change in the output signal that
cannot be corrected by calibration indicates possible transmitter damage. This may cause the output to be non-linear,
requiring transmitter replacement.
Remedy
