Questions and answers
how can i power the meter for bench testing and programming using single phase
To power the Landis+Gyr E650 Series 4 meter for bench testing and programming using single phase, you can supply the meter via the test terminal blocks from a suitable auxiliary source on the secondary side with the system switched off. This allows powering the meter without needing full three-phase voltage.

How to get a roc reading of the Landis +650
To obtain a ROC (Read-Out Code) reading from the Landis+Gyr E650 Series 4 meter, follow these steps using the optical interface:
1. Start the readout device according to its operating instructions.
2. Connect the reading head cable to the readout device.
3. Place the reading head in the "Readout" indentation on the plastic viewing window of the meter. The cable should point toward the terminal cover.
4. Start the data readout on the readout device as instructed.
5. After the readout is complete, remove the reading head from the meter.
The data can be read out according to IEC 62056-21 or DLMS, depending on the configuration and the communication unit present.

How to i take meter readings
I’m installing a E650 ZMD410C meter as a generation meter for a Solar PV system. The phase conductors are 70mm and therefore current transformers will be used to measure the power generated. The manual shows the connections for each CT (three phase). Does the meter require an addition power supply to operate? If the solar PV system is switched off how is the meter powered?
