Product Description
Power quality transducer which
can be used in 3 different oper-
ating modes:
- direct measurements for the
power quality analysis (LV or
MV/HV connection);
- indirect energy and power
measurements by means of
watt-hour meters (LV or MV/HV
connection);
- direct measurements for the
instantaneous variables (LV con-
nection) and indirect measure-

Software functions
Sampling management
Only for data logger. The
sample stored within the
selected time interval results
from the continuous average
of the measured values. The
average is calculated (min.
sample) with an interval within
two following measurements
of approx. 200 ms.
The variables, up to 8 can be
stored as average value, mini-
mum and maximum instanta-
neos values. Minimum is
intended as lowest value
among those sampled in the
programmed time interval.
Maximum is intended as
highest value among those
sampled in the programmed
time interval.

data logging".

Data logger function
The data are stored at time
intervals from 1 to 60 min.; up
to 8 instantaneous variables
can be selected.

Operating mode selection
- Direct measurements for

measurements for the ener-
gy variables (LV or MV/HV).
