Accuracies based
on:
1. sinusoidal voltage and current 4. definition of power
range as the product of
2. ambient temperature 23 °C current and voltage range, 0 ≤
IλI ≤ 1, (λ=Power factor=P/S)
3. warm up time 1h 5. calibration interval 12 month
4. definition of power range as the product of
current and voltage range, 0 ≤ IλI ≤ 1, (λ=Power factor=P/S)
5. calibration interval 12 month
All other values are derived from the current, voltage and
active power values. Accuracies for derived values depend on
the
functional relationship (e.g. S = I * U, ∆S/S = ∆I/I + ∆U/U) |
| Isolation |
All current and voltage
inputs isolated against each other, against remaining
electronic and against earth (1000V/CATIII) |
|
Synchronization |
The measurement is
synchronized on the signals period. There is a choice to
determine the period from „line“, „extern“,
u(t), i(t) as well as their envelopes, combined with
settable filters . By this very stable readings are
achieved, even at signals of
pulse width modulated frequency inverters and amplitude
modulated electronic ballasts. |
