It is a new generation intelligent transformation ratio testing instrument that uses a microcontroller as the core for measurement calculation and automatic control, with a fully Chinese menu operation interface. It has the advantages of intuitive display, good stability, high accuracy, wide measurement range, and does not require three-phase power supply on site.
Fully automatic ratio group tester, small in size, light in weight, high in accuracy, and good in stability. The fully automatic ratio group tester adopts a large screen LCD Chinese character display and menu operation, with a friendly interface. The ratio group can be tested in one go.
Precautions for using the fully automatic ratio group tester:
1. When using the fully automatic ratio group tester for measurement, do not touch the test sample.
2. If the test line is short circuited and the high and low voltage are reversed, the fuse will melt. After the insurance is blown, if measurement is carried out and it shows' measuring in progress' again, please wait! Stop later, please shut down, replace the fuse with the same capacity, and retest.
3. The connection should maintain good contact, and the instrument should be well grounded!
4. The workplace of the fully automatic ratio group tester should be away from strong electric fields, strong magnetic fields, and high-frequency equipment. The smaller the interference from the power supply, the better. It is recommended to use lighting wires. If the power interference is still significant, the instrument can be powered by an AC purification power supply with a capacity greater than 200VA.
5. When the fully automatic ratio group tester is working, if the LCD screen displays disorder, all buttons have no response, or the measured value is far from the actual value, please press the reset button, or turn off the power and operate again.
6. If there are no characters displayed on the monitor or the colors are very light, please adjust the brightness potentiometer to the appropriate position.
7. The fully automatic ratio group tester should be stored in a dry and ventilated place.
