Security requirements
Please read the instruction manual carefully before using
the clamp and pay special attention to the "Warnings."
Please follow the instructions in the "Warnings".
1. Please be very careful when the test voltage is higher
than 30V AC, and take care that your fingers do not
exceed the protection barrier of the test leads.
2. Do not measure voltage higher than the permitted limit
values.
3. Before use, please check the clamp and test leads; do
not carry out measurements if the leads are bare, the
caliper housing is damaged, there is no LCD display, etc.
4. The requirements of the safety regulations are met
only when the clamp is used in conjunction with the
supplied test leads. In the event that the cables are
damaged and need to be replaced, it is necessary to use
others of the same model and identical technical
specifications.
5. Please never carry out voltage measurements if the
test leads are connected to a current output.
6. Please do not expose the clamp to strong light, high
temperature or humidity.
Warning
Before use, please read this instruction manual
carefully. Especially the safety contents!

General description
The 3-phase wattmeter is a portable, smart harmonic power
tester with both current and power measurement. The
instrument is composed of three channels including voltage,
current and power as well as a single micro chip and is
equipped with powerful software for measurement and data
processing functions; It can measure, calculate and display
voltage, current, active power, power factor, apparent power,
passive power, frequency and harmonic parameters, with
stable performance and ease of operation. The instrument is
especially suitable for measuring and
