2020-02-05
The power supply voltage is less than the required value: the normal minimum power supply voltage is 9VDC, check the voltage value
Insufficient power of power supply: whether the power of power supply meets the requirements of rated load
Excessive load of acquisition circuit: check the circuit load
Pressure value exceeds the minimum range value: whether negative pressure is formed at the pressure tap of the transmitter
Pressure transmitter amplifier board burned out: repair or replacement
Impact or overpressure core damage: repair or replace
