changing caused by transport and other outside factors, thus greatly improving the system
stability and reliability.
TTThe system uses domestic pioneering digital true reactive measurement technology.
Reactive measurement can be truly affected by the voltage and current, phase asymmetry,
frequency change and others, so the reactive accuracy is raised to 0.1% for the first time in

2.3 Operating Precautions
TTWarning: This instrument is a live working device, so for your safety, please observe
the relevant provisions of state work safety, and operate in strict accordance
with the operating instructions to field calibration of power metering devices.
TTDo not clip the pulse line clamp to voltage terminal of energy meter, otherwise it will
damage the instrument;
TTDo not insert the voltage terminal line into the current terminal port, otherwise it will damage
the instrument;
TTDo not insert the current terminal line into the voltage terminal port, otherwise it will damage
the instrument;
TTSelect correctly working power supply (Note: the power range is AC57.7V ~ 480V);
TTSelect correctly current range, and the current range generally does not exceed 220% of
the rating;
TTWhen measuring three-phase three-wire, B-phase voltage must be connected to the
common COM of voltage terminals;
TTEach clip-on ammeter connects to the positive and negative terminal: "+" terminal is the

current input, and "-" terminal is the current output, which can not be wrong;
TTClip-on ammeter colors represent different phases: Yellow-A phase, Green-B phase, and
Red-C phase;
TTA different phase of clip-on ammeter will not be used interchangeably, otherwise it will affect
