Hello,
I am a new user of a 3 phase meter and I have a question:
Why the meter shows me negative measurement values. I have the currents upside down. K Against L.
I am attaching a picture:
Thank you!!!

Welcome to the forum!
To your issue:
(a) negative power values without a power generator (e.g. photovoltaic plant) are obviously provoked by incorrect mounted current clamps. They have to be turned in the opposite direction.
(b) low power factors indicate a wrong connection of the voltage terminals: phase VA must coincide with the wire where current clamp A is mounted! Same for VB/clamp B and VC/clamp C.
Suppose, you’re suffering with both issues, (a) and (b).
Thanks for the reply.
It is already working properly. What you wrote under (a) was wrong.
Thank you for your help!!!
