● Voltage non-contact, safe and convenient
● Anti-stealing function
● 10kV high voltage CT magnification check
● Do not open the watch cover, do not move the lead seal for inspection
● Check for wrong connection of electric energy meter
● Comprehensive error measurement of metering devices
● Non-contact voltage sampling, no need to break the lead seal, no need to open the cover, easy to use, fast and safe.
● The overall (comprehensive) error measurement of the low-voltage metering device can measure the comprehensive error of the metering device composed of current transformers and meters.
● It can measure the transformation ratio, polarity and phase-to-phase correspondence of 35KV and below high and low voltage current transformers.
● It can measure the current amplitude of high and low voltage lines up to 35KV.
● Read event records such as frozen power, load curve, loss of voltage and current, programming, and cover opening of the electric energy meter, and support current communication protocols such as 645 and 698.
● Identify 48 kinds of common three-phase three-wire and 96 kinds of three-phase four-wire wiring errors, and prompt the correction coefficient.
● It can measure the waveforms and harmonics of three-phase voltage and current, and can store all harmonic data.
● Equipped with a telescopic insulation rod, it is easy to carry.
● There are two power supply modes of lithium battery and test line, wide range of working power.
● The wireless communication method is adopted between the host and the high-voltage clamp meter, which is safe and reliable.
