FAQ

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.
