Averaging time
(1)
200 ms, 1 s, 3 s, 5 s, 10 s, 15 s, 30 s, 1 min, 3 min, 5 min, 10 min, 15 min,
30 min, 60 min, 120 min.

RMS(1/2)
and I
RMS(1/2)
)

Waveforms
Option to record three periods of waveforms for active channels, after
each averaging period
Recording activation mode
manual
starting at the first detected event
scheduled (four defined time intervals)
Measurement Points
4 independent user configurations, defined memory allocation space on
the memory card, the option to allocate the whole space to a given point
Recording time
Depending on the configuration (see 2.7.3)
Memory
Built-in 8 GB memory card
Memory Model
Linear
Security
Key lock to prevent unauthorized access, data read-out lock with PIN
(1) Averaging times shorter than 10 sec. are in fact equal to a multiple of the mains cycle:
200 ms – 10/12 cycles, 1 s – 50/60 cycles, 3 s – 150/180 cycles, 5 s – 250/300 cycles.
(2) U
RMS(1/2)
and I
RMS(1/2)
are effective values for one cycle, refreshed every half-cycle.
(3) Averaging periods min./max. 200 ms, 1 s, 3 s, 5 s are in fact equal to a multiple of the mains cycle: 200 ms –
10/12 cycles, 1 s – 50/60 cycles, 3 s – 150/180 cycles, 5 s – 250/300 cycles
