General Instructions
This circuit analyzer is a special test device
designed for AC low-voltage distribution line quick
fault location. With simple operation, accurate
measurement and other features, it can detect
multiple problems on a line, such as causing to
electric shock, electrical fire, abnormal operation
of equipment, etc.
Functions:
• TRMS measuring AC voltage
Artificial load 12A, 15A, 20A measuring line drop
Measuring phase voltage, neutral line (zero line)
voltage to earth, peak voltage, frequency
Measuring phase (live line), neutral line (zero line),
earth line conductor impedance
Identifying 3-wire socket connection mode (zero
for left and live for right, having earth line or not)
Test the reliability of residual current device (RCD)
and response action time
Test the reliability of GFCI action and response
action time
Backlight function and data hold function

Warning
Do not use this instrument without reading,
understanding and following the instructions
in this manual. Read and follow them carefully,
as well as all warnings and instructions marked
on the instrument!
To prevent damages to the instrument, it should
not be used for measuring the output of UPS
equipment, nor for measuring adjustable light
and square wave generator!
For measurement accurency during repeated
usage, allow at least 30 seconds between two
consecutive measurements to facilitate
equipment cooling when measuring voltage
drop and cable impedance.
To ensure accurate measurement data, please
check whether there is important load or heavy
load in the line before testing. Turn off the heavy
load, if necessary, then retest.
