● Laptop serial communication, fully save and record test data (optional function)

● For fans, oilfield pumping units, coal mine scraper conveyors and other power frequency line equipment, can perform full process dynamic measurement and energy-saving analysis.

● Reference to national standard GB12497-2006 "Three-phase asynchronous motor economic operation"

Using the three-phase vector diagram function, it is convenient for users to judge whether the line wiring is correct and whether the line working state is normal, with miswiring judgment function.

Combined with computer serial communication, instantaneous data of various electrical equipment can be fully recorded and stored. With dedicated computer software, data analysis can be performed, and curves of voltage, current, power (can distinguish positive and negative power) and other data during the operation of various electrical equipment can be drawn and printed. This provides correct scientific basis for reasonable adjustment of oilfield pumping unit balance blocks, fan efficiency, coal mine electrical equipment, railway, refrigeration, electric power, chemical, machinery and other industries in production, manufacturing, energy-saving management and detection.

This tester has the advantages of large memory motor parameter capacity, high measurement accuracy, simple operation, complete functions, and multiple uses in one machine. It solves the problem of motor negative power testing, fills the technical gap of similar domestic instruments, and is truly an ideal intelligent power testing tool.
