1 Press MENU key to select inactive power (kWar)+voltage(V)+current(A)
2 Jaw shall be fixed to measured conduits in corresponding phase locations. That is, user
shall measure a certain phase of three-phase circuit so that jaw is on corresponding conduit.
3 Please refer to Figure 4, 5 & 6 of UT240 manual for wiring of three-phase four-wire system,
three-phase three-wire system or single-phase two-wire system.
4 As shown in Figure 9-1, please press SELECT key to select the
1st phase location of 1 for three-phase four-wire system of
load. It can display apparent power, voltage and current of phase
location 1.
7.2Inactive power(kWar)+Voltage(V)+Current(A)
Figure
As shown in Figure 9-2, please press key to measure
total three-phase power. Current measured power of the 1st
phase location also shall be calculated and saved.
Figure
As shown in Figure 9-3, please press SELECT key to select
the 2nd phase location. It also can display active power, voltage
and current of phase location of 2.
Figure
As shown in Figure 9-4, please press key to measure
total three-phase power. Current measured power of the 2nd
phase location also shall be calculated and saved.
Figure
As shown in Figure 9-5, please press SELECT key to select
the 3rd phase location. It also can display active power,voltage
and current of phase location of 3.
Figure
As shown in Figure 9-6, please press key to measure
total three-phase power. Current measured power of the 3rd
phase location also shall be calculated and saved.
Figure
As shown in Figure 9-7, total three-phase active power
can be displayed by pressing SELECT key finally.
Figure
Measurement operation of the 1st and 2nd phase locations
is the same as that of three-phase four-wire system. As
shown in Figure 9-8, total three-phase inactive power can be
displayed by pressing SELECT key after tripping the 3rd
phase location of measurement.
Figure
5 The maximum measuring range is 600kWar for single-phase inactive power to display
OL symbol if exceeding the range. The maximum range is 1,800KWar for total three-
phase active power. It also will display OL symbol if exceeding the range.
