1. This instrument 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.
2.The oil cup should be kept clean, and it should be filled with dry and qualified insulating oil during the non-use period to keep the oil cup from moisture.
3. After the electrode has been used continuously for one month, an inspection should be carried out to check whether the electrode gap has changed, and use a magnifying glass to observe whether the electrode surface is darkened. If this phenomenon occurs, the insulating oil dielectric strength tester should use silk cloth. Wipe the electrode surface and readjust the electrode gap to make it meet the requirements. 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
How to clean the oil cup
1) Wipe the electrode surface and electrode rod repeatedly with a clean silk cloth.
2) Adjust the electrode gap with a standard gauge.
3) Clean it with petroleum ether or ethanol 3-4 times, then dry it with a hair dryer, and clean it 2-3 times with the oil sample to be tested.
How to clean the stir bar
1) Insulating oil dielectric strength tester Wipe the stirrer repeatedly with a clean silk cloth until there are no fine particles on the surface, and avoid touching the surface of the stirrer 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 and immerse it in the oil sample to be tested and wash it repeatedly.
