Focus areas
- Check that the power meter is properly connected to the CT (current transformer) before configuring the power meter.
- The white wire / S1 of the transformer must be connected to the + terminal of the energy meter
- The black wire / S2 of the transformer should be connected to the - terminal of the energy meter.
- If connected incorrectly, there is the possibility that the current will be measured incorrectly. For example: connecting the black wire to the positive terminal of the power meter.
- See also the following section in the manual Eastron energy meters - installation of a CT.

Open the settings
1. Press for 3 seconds until the password screen is visible
The default password is “1000. Enter the password using up and down:
and
If the password is different, you can navigate to the other numbers by pressing the E button once. You can then adjust them with the M and P buttons.
Press for 3 seconds to confirm the password.
Changes to the settings are saved by pressing and holding the E button for 3 seconds.
If the password is correct you will enter the slave id menu by default.
Changing the slave id
The range goes from 001 to 247 | |
In the setup menu, press theand to select the address ID | |
Press to start the selection procedure. The selected setting blinks. | |
Use the buttons and to select the Modbus address (001 to 247). |
After completing the input procedure, press to confirm the setting and press to return to the main settings menu.
If you see the message 'GOOD' the setting has been successfully saved:

CT clamp setting
The CT options set the secondary current (CT2 5A or 1A) of the
Current Transformer (CT) used with the meter.
Use the A and B buttons to select the menu option. | |
Secondary CT setting: press and hold the button to set the secondary CT option: 5A (default) or 1A. | |
Set the value of the CT ratio: Press and hold to open the CT ratio setting screen. The range is 0001 to 9999 |
The CT-ratio is the primary CT divided by the secondary CT.
For example, for 200/5A current transformers whose CT1 = 200 and CT2 = 5:
200 ÷ 5 = 40, so the CT Ratio would then be 0040.
Or in the case of a CT100/1A, the ratio is 100 / 1 = 100
On the MID version, you can only program the CT-Ratio one time.
This energy meter can be set to operate with CT terminals from 1A to 5A secondary current.
When choosing current transformers, the primary current of the transformers should be equal to or greater than the load current of the circuit you want to measure.
To avoid errors in energy measurement, the P1 port of the CT should be pointed toward the power supply. However, if the P2 port is facing the power supply, you can still correct it using the Eastron energy meters manual.
