7. Measurement
Electric Shock, Danger! Only trained and authorized staff is allowed
to operate and should strictly observe safety rules, to avoid any
damage to the meter or personal injury in case of electric shock.
Danger! Do not measure voltage above 600V, to avoid any damage
to the meter or personal injury in case of electric shock
Danger! Do not measure current above 20A which may damage
the meter!
Connect wires as indicated in the manual and avoid wrong insert
between I1, I2 and I3
Disconnect test wires with measured circuits before pulling them
out of the meter after measurement.
Phase measuring relations: U1U2, U2U3, U3U1, I1I2, I2I3, I3I1,
U1I1, U2I2, U3I3, the former phase of signal always precedes the
latter.
Voltage terminals U1, U2, U3 are named the same with red marks
on current clamps.
The Current clamping direction should accord with those of red
marks during phase measuring
This meter can measure three-phase voltage and current, phase angle
between voltages, currents and both, frequency, active and reactive power,
apparent power, power factor, three-phase sum of current vector, and also
differentiate phase sequence, inductive and capacitive circuits, ect.
Testing wire connection is shown as below:
1. Single Phase Measuring:
Connect measured voltage lines L, N to yellow U1 and black COM
terminals, then current clamp I1 grasping L line. It also works by choosing
Green U2, black COM, I2 or red U3, black COM and I3.
