Precautions
1. Be sure to read the instructions carefully before using the instrument.
2. Operation of the instrument should have general knowledge of electrical equipment or instruments.
3. It can work normally within the ambient temperature of -5℃~40℃ and relative humidity ≤80%, but when used outdoors, avoid rain and direct sunlight on the LCD screen.
4. Turn on the power switch only after all leads are connected.
5. After the test, wait for the discharge to complete before removing the test leads.
6. Do not move the test clips during the test.
7. If the current is too small, two or more wires can be connected in parallel as one measurement path, and unused wires should be short-circuited with the black wire.
8. The power socket is equipped with a protective ground wire; please insert the plug into a three-hole socket with ground.

8. The instrument is equipped with a high-speed printer to print test results.
Product Introduction:
The On-Load Tap Changer Characteristics Tester is a comprehensive measuring instrument used to measure and analyze the electrical performance indicators of on-load tap changers of power transformers and special transformers in the power system, according to the principles of the "Regulations for Handover and Preventive Tests of Power Equipment" and related regulations..It uses computer control and a specially designed measurement circuit to measure parameters such as transition time, transition waveform, transition resistance, and three-phase synchronization of on-load tap changers. With a brand-new testing principle and microcomputer technology, it enables testing of the performance of on-load tap changers of various power transformers without disassembling or lifting the switch on site, and displays and prints the transition waveform and its parameters. According to needs and site conditions, measurement can be directly performed from the tap changer leads, or directly from the transformer three-phase bushings and neutral point wiring.
