FAQ

1)What operating modes are available for the MEJYC-W80Y Insulating Oil Dielectric Strength Tester?

Answer: The instrument offers three program options: GB1986 and GB2002 national standard methods, plus a custom operation mode. This flexibility accommodates diverse testing requirements with convenient operation.

2)What environments should be avoided when using the MEJYC-W80Y Insulating Oil Dielectric Strength Tester?

Answer: Avoid locations exposed to rain, corrosive gases, high dust concentrations, high temperatures, or direct sunlight. Ensure the ambient temperature is between 0°C and 40°C (32°F and 104°F) with relative humidity ≤85% to guarantee proper instrument operation.

3)Why must the oil cup and stirring paddle be rinsed with the test oil sample after cleaning?

Answer: Rinsing with the test oil sample prevents contamination from residual anhydrous ethanol or other impurities, ensuring the purity of the oil sample remains unaffected during testing. This guarantees the accuracy of measurement results.
