Insulating oil dielectric strength tester is mainly used for voltage resistance test of insulating oil. It can carry out a single test or multiple tests and automatically calculate the average value and print it out for the result. The insulating oil dielectric strength tester can automatically test, but maintenance is essential. The specific maintenance methods are as follows:

1. After the electrode has been used continuously for one month, an inspection should be carried out to check whether the electrode gap has changed. Use a magnifying glass to observe whether the electrode surface is darkened. If this phenomenon occurs, wipe the electrode surface with silk cloth and readjust it. The electrode gap makes it meet the requirements.

2. This tester can be used indoors and outdoors, but it should be used in places such as rain, corrosive gas, excessive dust, high temperature or direct sunlight.

3. The oil cup should be kept clean, and should be filled with dry and qualified insulating oil during the period of non-use to keep the oil cup from damp.

4. The use, repair, maintenance and adjustment of the insulating oil dielectric strength tester should be carried out by professionals.

5. Replace the printer ribbon: the ribbon cartridge has been installed before the printer leaves the factory, but after a period of use, the ribbon cartridge needs to be replaced.

6. Replace the printer roll paper: the printer has installed roll paper before leaving the factory, and you need to install a new roll paper after use.

7. How to clean the oil cup of the insulating oil dielectric strength tester:

1) Wipe the electrode surface and electrode rod repeatedly with a clean silk cloth.

2) Adjust the electrode gap with standard gauges.

3) Use petroleum ether or ethanol to clean 3-4 times, then blow dry with a hair dryer, and clean the oil sample to be tested 2-3 times.

8. How to clean the stir bar:

1) Wipe the agitator repeatedly with a clean silk cloth until there are no fine particles on the surface. Avoid touching the surface of the agitator with your hands.

2) Clamp the stirrer with tweezers, immerse it in absolute ethanol and wash it repeatedly, and then dry it with a hair dryer.

3) Clamp the stirrer with tweezers, immerse it in the oil sample to be tested and wash it repeatedly.
