Why is the measured value incorrect on my Energometrika PMAC770?
- J
  Joshua PadillaAug 2, 2025
  If the measured value is incorrect, several factors could be at play. If the voltage measurement is incorrect, verify the neutral point is reliably connected, the measured voltage matches the meter's rated parameters, and the PT ratio is set correctly. If the current measurement is incorrect, check that the measured current matches the meter's rated parameters and that the CT ratio is set correctly.

What to do if the upper end device can't communicate with the Energometrika PMAC770 Measuring Instruments?
- R
  Rachel HowardAug 7, 2025
  If the upper end device cannot communicate with the meter, there might be an issue with the communication settings. First, check if the meter's address is consistent with its definition and ensure there are no duplicate addresses on the network. Secondly, confirm that the baud rate setting on the meter matches the upper end device.

How to fix no or incorrect pulse output on Energometrika PMAC770?
- S
  scottcharlesAug 11, 2025
  If there is no pulse output or the pulse output is incorrect, the issue might be with the pulse settings. Verify that the pulse output channels are activated and that the pulse constant is set correctly.

What causes the DI status to not change on Energometrika PMAC770?
- S
  shepardbrianAug 16, 2025
  If the DI status is not changing, several factors could be the cause: * Incorrect power measurement: Ensure the connection mode is set correctly, the phase sequence for voltage and current is correct, and the wiring of current terminals is correct. * Incorrect DI operating voltage: Check that the types of external nodes match the rated parameters of the meter and that the external connection is correct. * Relay control issues: Verify the communication link is correct and the current relay is under the correct control mode.

Why does my Energometrika Measuring Instruments meter have no indication after power supply is on?
- S
  Sharon PotterAug 21, 2025
  If the meter shows no indication after turning on the power supply, it might be due to a power supply issue. Check if the correct working voltage has been applied to the L/+ and N/- terminals of the meter. Also, check if the fuse for the control power supply has blown.
