| Accuracies based
on |
1. sinusoidal voltages and currents
2. ambient temperature 23°C
3. warm up time 1h
4. definition of power range as the product of current and
voltage measuring range, 0 ≤λ≤
1
5. calibration interval 12 month |
| Other values |
All other values
are derived from the values for current, voltage and active
power values.
Accuracies for the derived values depends on relationship (e.g. S = I * U,
ΔS/S = ΔI/I + ΔU/U) |
|
Synchronization |
The measurement is
synchronized on the signals period.
There is a choice to determine the period from u(t), i(t),
p(t), further u²(t), i²(t)
by using a settable filter . By this very stable readings
are achieved, even at signals of pulse width modulated
frequency inverter and amplitude modulated electronic
ballast, synchronization also with external signal or „Line“ |
