Measurements and precision in conformity with
- Current: cl.0,5
- Voltage: cl.0,5
- Frequency: ± 0,1 Hz
- Instantaneous total active power, phase, average value and max.
average value : cl.1
- Instantaneous total reactive power, phase, average value and max.
average value : cl.2
- Instantaneous total apparent power, phase, average value and
max. average value : cl.1
- Power Factor : cl.1
- Total and partial active energy, positive and negative: : cl.1
- Total and partial reactive energy, positive and negative : cl.2
- THD cl.2
Average current - Average power:
- Measurement: current-apparent, reactive, active power
- Calculation: moving average, on the selected period
- Average time: 5/8/10/15/20/30/60min.
- Average time: same for all the magnitudes
Hour meter:
- Counting of operating hours and minutes
- Start count: can be selected, presence of voltage or power
- Voltage: Phase voltage > 20V
- Three phase rated active power
- Programmable value : 0...50% Pn
Pn = three phase rated active power

Diagnostic, Phase sequence correction:
In the software there is a diagnostic and correction algorithm of the
voltmetric and amperometric connection sequence.
The function can be activated on request and password protected: it
can display and modify the wiring sequence with the following
limitations:
1) The neutral conductor
positioned
(terminal 11)
2) There are no conductor crossings between different CT
(
e.g. on phase 1 of the device there is a cable from CT 1 and on the other a cable
from CT 2)
3) The power factor must be between 0.9cap and 0.7ind for each
phase.
