1. General introduction

YJJ-502 is developed according to the national standard GB-86 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 by YJJ-502. You can print the test result by the micro printer internal the tester. Of course, you can upload the test data to PC from RS232 for data analyzing. The special circuit design makes the tester has a good performance at stability and anti-noise.
