F. Active Energy (main display) + Time (secondary
display) Measurement
Warning
To avoid damages to the Meter or harms to you, do
you measure higher than AC voltage 600V rms and
AC current 1000A rms.
To test for Active Energy (main display) + Time
(secondary display), connect the Meter as follows:
1.
2.
3.
4.
Press the
MENU
to select Power factor (main
display) + Phase angle (secondary display) range.
Press the lever to open the transformer jaw, and
clamp them to the corrresponding phase of tested
conductor. If user needs to mesaure any phase of
the 3 phase, then clamp them to that phaseís
conductor.
The connecting method of 3 phase 4 wires, 3 phases
3 wires or single phase 2 wires, see figure 6, 7 and
8
Press
SELECT
to choose one of the three phases
(
1
,
2
,
3
), see figure 23.
The double display shows the value of tested objectís
active engergy kWh value and the measuring time
of the corresponding phase.
The measuring reading gets increasing along with
the time increases. Press
HOLD
to read a particular
time kWh value. Then the reading and time are
locked, but still continuous accumulate measuring
time.
After read the data, press
HOLD
again to continous
measurement. kWh value continous accumulate
and the measuring time jumps to the present
measuring time.
When the measuring time is over 24 hours or the
Meter is switched to other measuring ranges, active
energy measuring will stop.
