General introduction
YJJ-502A is developed according to the national standard GB-86 & IEC60156 Insulating Oil Dielectric Strength Testing Method .LCD screen can display test procedure and test result. All the human interaction operations complete by the rotating mouse .It is very easy for customers to measure the breakdown voltage of all kinds of oil. It can print the test result by the built-in micro printer. Of course, it can upload the test data to PC from RS232 & USB for data analyzing. The special circuit design makes the tester has a good performance at stability and anti-noise.
