| Range selection |
Auto, manual or
remote-controlled, separately for each current and voltage
channel, input of factors for transformers (U and I), level
control display for each channel in the status line |
| Isolation |
Current and voltage path may
float against each other and against earth up to 1500V |
| Measuring method |
Simultaneous sampling of the
current and voltage inputs and A/D conversion of the
instantaneous values |
Measuring cycle,
synchronization,
averaging |
For the measurement of the
trms values for current, voltage and active power, the
measuring cycle time is adjustable in the range of 100ms to
60s. The synchronization can be performed on the measuring
signal, the fundamental harmonic of the measuring signal,
the mains or an external signal. A single measurement with
automatic stop after 1 measuring cycle is possible.
Averaging over 1 to 16 measuring cycles. |

| Accuracies based
on |
1. sinusoidal voltages and currents
2. ambient temperature 20...25°C
3. warm up time 15 minutes
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. Accuracies for the derived values depends on the
functional relation (e.g. S = I * U,
ΔS/S =
ΔI/I +
ΔU/U) |
