Troubleshooting
Error description
Potential cause
Corrective action
no output signal
• supply voltage is not connected
• incorrect supply voltage
• defective reverse polarity
protection diode
• defective input protection diode
• connect correct supply voltage
• connect the correct supply
voltage (see rating plate).
• send the instrument to the
manufacturer for repair
• send the instrument to the
manufacturer for repair
output signal is constant,
despite change in
pressure
• defective output protection diode
• pressure ports reversed
• send the instrument to the
manufacturer for repair
• connect the pressure as
described in Section 3.1
output signal incorrect
• defective output protection diode
• defective pressure measurement
cell
• send the instrument to the
manufacturer for repair
• send the instrument to the
manufacturer for repair
zero point cannot be
adjusted using P1
• defective pressure measurement
cell
• send the instrument to the
manufacturer for repair
