Power
Factor B
6D –
Power factor. The output will be
between -0.950 and 1.000.
Positive power factor is defined as
current lagging voltage (inductive).
Negative power factor is defined as
voltage lagging current
(capacitive).
If the power factor
is 0.95
)6D?<CR>
Returns:
+0.950
Phase
Angle B
6E –
Phase angle. The output will be
between 180.000 and -180.000.
If the phase angle measured is 60
degrees
)6E?<CR>
Returns:
+60.000
