Power Quality Analyzer PowerPad
®
IV Model 8345
If a value cannot be calculated, the instrument will display - - -. For example, no
value can be calculated because the instrument is not connected to the network.
To change the display filter, use the ▲ ▼ buttons. The available display
filters depend on the chosen distribution network and connection type
The
4V
display filter displays the data of the phase-to-neut
ral voltages.
The energy calculation starts at fixed times: 00.00, 00.10, 00.20, 00.30, 00.40,
00.50, 01.00, 01.10, etc. If you switch your instrument on at 08.01, the first P
st
value will be displayed at 08.20.
The calculation of the P
lt
starts at fixed times: 00.00, 02.00, 04.00, 06.00, 08.00,
10.00, 12.00, etc. If you switch your instrument on at 08.01, the first P
lt
value will
be displayed at 12.00 in the case of a fixed window and at 10.10 in the case of a
sliding window.
Only calculations completed with the fixed window are recognized by IEC
standard 61000-4-30.
The
4A
display filter displays the extreme values
of the currents.
The
L2
display filter displays the voltage and current data of
phase 2.
The
L1
,
L3
, and
N
display filters are similar but concern phase 1, phase 3, and
the neutral.
