The single-phase relay protection tester is composed of single-chip microcomputer, logic control unit, high-precision data acquisition unit, LCD liquid crystal display, real-time clock, printer, etc., with high measurement accuracy and good repeatability. The instrument also has the advantages of beautiful appearance, reliable performance, simple operation and complete functions. It is an ideal testing instrument for checking relay protection devices.
This instrument can test various AC and DC voltage values, release voltage values, various contacts, normally open, normally closed, switching, delayed pull-in time and disconnection time. They are automatically tested three times and the average value of the three times is automatically calculated. And can print the test results, so what are the features of this instrument? Today, the editor will give you a detailed introduction to the features of this instrument:
1. The instrument is equipped with a separate loop power supply with adjustable output (wide adjustment range), which can be used as a voltage source alone;
2. Using digital display, the reading is intuitive, and it is very convenient to use;
3. The instrument is compact in structure, light in volume and easy to carry;
4. The main circuit of the instrument is equipped with a loop. There is no need to attach a multimeter and instrument meter. The voltage and current of the main loop are directly displayed.
