Precautions during use
The electrostatic tester is specifically designed for the handling of static electricity and should be kept away from water, oil, solvents and other conductive contaminants. Exposure to such pollutants will cause electrical insulation faults in the products. Be especially careful to ensure that no dew forms in the environment. The electrostatic tester should be stored and used in an environment with a humidity of less than 60%.
Do not insert any objects into the opening used to fix the sensor, and do not allow any foreign objects to enter the opening of the sensor. The electrostatic tester should not be operated in an environment with corrosive acid/alkali fumes or corrosive gases such as chlorine. The normal operating conditions are listed on its nameplate.
When not in use, please turn off the instrument. For the accurate measurement of the instrument, please ground it correctly. This instrument is very likely to be damaged if it drops. If such an incident occurs, it should be handed over to an authorized technician for a thorough inspection and necessary repairs. This instrument is an electronic device, and the sensors it contains may be highly sensitive to mechanical vibrations and shocks. Of course, it also contains a microprocessor chip and electronic circuits, so it cannot be used in an environment with a lot of electronic noise.
