Automatic
setting
of
internal
parameters through the instrument in compliance
with voltage quality network requirements of
guideline EN50160
➢
kWh
→
Automatic setting of internal parameters
through the instrument for the analysis of
power/energy problems
➢
HARM
→
Automatic setting of internal parameters
by the instrument for voltage/current harmonic
analysis
➢

Automatic setting of all recording
parameters
Confirm each setting by touching the
icon or touch
the

6. Insert the connectors of the test cables into the
B1, B2, B3, B4
input terminals for
voltage measurements depending on the selected connection type. Insert the remaining
free end of the cables into the corresponding crocodiles or tips. Connect crocodiles or
test leads to phase L1, L2, L3 and N according to the images in § 6.3.1. Connect the
clamps to
I1, I2, I3
and
I4
inputs and to the phase conductors according to the images in
§ 6.3.1. The arrow on the clamp must point in the direction in which the current normally
flows from the generator to the load
6.3.3. Display of measurements
7. The screen like the one to the side shows the numerical
real-time values of electric parameters, referred to a
three-phase 4-wire system. For the meaning of the
parameters, please refer to § 12.4
Touch the
icon to show the pages (the number
of which depends on the type of selected connections)
of the TRMS values relevant to total powers, total
power factors and values referred to the single phases
as shown in the following screen
Press the
