Introduction:
One operation, the microcomputer automatically completes the entire measurement process. It is a dielectric loss measurement device. The variable frequency anti-interference dielectric loss tester can also
Safety Measures:
1. Before using this instrument, be sure to read this manual carefully.
2. The operator should have general knowledge of electrical equipment or instruments.
3. The instrument should avoid severe vibration.
4. The instrument must be reliably grounded to prevent electric shock hazards.
5. After the test, press the reset button, turn off the power switch, and strictly prohibit disassembling test cables or replacing oil samples while energized.
6. Daily maintenance of the instrument must be carried out without power supply, otherwise high voltage danger
