Main features
1. Both the host and the extension adopt 4.2-inch color LCD displays, which display all measurement parameters on one screen;
2. Host+module operation: The wireless energy acquisition module collects the energy pulses from the secondary side energy meter of the transformer and transmits them wirelessly to the inspection host. After receiving the signal, the inspection host converts the system energy measured by the energy meter through the PT ratio and CT ratio of the energy meter, and measures the voltage, current, power phase, frequency, power factor, and vector diagram at the user meter end;
3. Host+extension work: The extension measures the secondary side voltage, current, power phase, frequency, power factor, and vector diagram of the transformer, wirelessly transmits electrical energy to the host, and the host measures the user meter terminal voltage, current, power phase, frequency, power factor, and vector diagram, and receives synchronous wireless signals from the extension to automatically calculate the line loss rate;
4. Automatically identify incorrect wiring of the energy meter, with 48 types of three-phase three wire and 96 types of three-phase four wire, and equipped with full limit error analysis function;
5. Can input multiple information such as Chinese Pinyin, letters, symbols, numbers, etc;
6. Equipped with 500A and 1000A clamp gauges, directly measure the transformation ratio of low-voltage current transformers. Convenient to search for faults such as open circuits, poor contacts, internal inter turn short circuits, and whether the nameplate transformation ratio does not match the actual transformation ratio in the CT secondary circuit;
7. Wiring simulation function, the instrument can simulate various wiring on site without connecting voltage and current signals, and obtain corresponding wiring results. Can be used as a training tool for line checking to improve the line checking skills of on-site staff;
8. There is no adjustable resistor inside the instrument, and all errors are corrected using software;
9. Built in large capacity memory, capable of storing 1000 sets of measurement data;
10. The electric energy accumulation function can be used to verify electric energy meters without electric energy pulse output, or as a test for energy-saving indicators;
11. Measure the waveforms and 2-51st harmonics of the voltage and current of phases A, B, and C to timely understand the power supply quality of the power grid.
