Danger: Electricity! Must operated by the qualified personnel that
trained and authorized . The operator must strictly abide by the
safety rules, otherwise there is a danger of electric shock,
resulting in personal injury or equipment damage.
Danger! Cannot be used to measure voltage lines exceeding 600V,
otherwise there is a danger of electric shock, resulting in personal
injury or equipment damage.
Danger! Cannot be used to measure the lines more than 20A, may damage
the equipment.
Must strictly follow the manual instructions to connect, I1, I2 cannot be
inserted opposite
After the test is completed, the test line must be evacuated from the line
before removed from the meter.
The phase test relationship of this instrument: U1U2
、
I1I2
、
U1I1
、
U2I2,
the phase of each relation measured is the phase of 1 signal advanced 2
signals.
U1, U2 voltage jacks and corresponding current clamp upward right
arrow are the same.
The direction of the current input clamp in phase testing is the same as
the direction of the arrow sign on the clamp.
This instrument can test AC voltage, current, phase between voltages, phase
between currents, phase between voltage and current, frequency, active power,
reactive power, apparent power, power factor, inductive and capacitive circuits of
two lines.
Test wiring is as follows:
Single-phase test: The tested voltage lines L and N correspond to the U1 red
and COM black jacks of the access instrument, and the current clamp I1 clamps the
