For example: … I have installed an Elnet Meter LT (for example, applicable also on other Elnet devices).
The voltage and currents are absolutely correct – I have also checked them with an clamp ammeter (current pliers).
However, when I observe the measuring results, something strange is happening:
Cos Fi and Reactive energy appear to be incorrect.
There must be something wrong with the Elnet meter….
Solution: In 99,99% of cases the wiring is incorrect. Check again the wiring. The voltages (V1, V2, V3) should be aligned with the currents (L1, L2, L3). The most common situation is that there is a mix in the connection. For example: Voltage V1 has the Current L2 and Voltage 2 has the Current L1. Therefore the devices calculates wrong results.
The wiring should be absolute correct. To check it run also the Wiring test. Go to Technical menu and type in the code 11. Everything should be OK.
