U rms
Effective voltage applied to the test object
U rms sqrt(3)
Effective voltage applied to the test object multiplied by

3. E.g.
to get Line-Line voltage from the Line-Ground value.
I
eff Ref
Effective Current through C
N
I
eff Test
Effective Current through C
X
Frequency
Measured frequency of applied voltage
Line Frequency
Measured Line Frequency
S / N Ratio
Signal / Noise Ratio shows the signal noise ratio.
The noise will be measured while switching high voltage on
during calibrating noise. To determinate the noise signal again,
the high voltage can be switch off and on again.

Y
X
Complex Admittance of the test object. Shown in absolute value
and phase-angle


(Zx)
Phase-angle of the complex Impedance of the test object
I
mag(Lp)
Effective magnetization current
