Q: No display on power?

A: Check whether the supply voltage is within the operating voltage range.


Q: Incorrect reading of voltage,current,electricty,etc?

A: Checking that the voltage/current ratio setting are correct; Checking whether the wiring mode setting is consistent with the actual situation;

Checking whether the voltage transformer and current transformer are in good condition.


Q: Abnormal communication?

A: Check whether the adress,baud rate,check bits in the communication; Setting are consistent with the host computer;

Check whether the RS485 converter is normal; Check the connection is corrent if the resistor above 120 ohm is connected in parallel at the communication end.
