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.

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 |
| Secondary CT setting: press and hold the |
| Set the value of the CT ratio: Press and hold |
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.
