Hi hmani,
I would appreciate your help!
I tried to give all calibration information in the message above.
But step by step...
PhaseResolution 306E-6d, freq: 50
Inductive case:
UL1 = 110V, 60°
IL1 = 1A, 0°
afwatthr 14611d, afvarhr 25126d, Error 3113E-6d (Error with calculator: 0.178°)
bfwatthr 14616d, bfvarhr 25142d, Error 2985E-6d
cfwatthr 14630d, cfvarhr 25155d, Error 3177E-6d
Error is positive and 512d is added:
PHCALA 522d, PHCALB 522d,PHCALC 522d
Additional information:
* The Error calculation is a bit unaccurate due to a tan⁻1 approximation, but sign is correct!
* all other energy counter registers are 0
Capacitive case:
UL1 = 110V, -60°
IL1 = 1A, 0°
afwatthr 14472d, afvarhr 25240d, Error -2986E-6d (Error with calculator: -0.171°)
bfwatthr 14455d, bfvarhr 25204d, Error -2877E-6d
cfwatthr 14460d, cfvarhr 25223d, Error -3053E-6d
Error is negative, nothing is added:
PHCALA 10d, PHCALB 9d,PHCALC 10d
* The Error calculation is a bit unaccurate due to a tan⁻1 approximation, but sign is correct!
* all other energy counter registers are 0
It seems, that only the sign of the Error is wrong...
I will try to do some energy measurements later on.
Thanks!
