Please let me know I have TES 1600 Insulation Tester it has three selections for testing resistance:
1 ) 200Mohms @250V
2) 200Mohms @500V
3) 2000Mohms @ 2000V
Problem is, I did not connect its testing leads it should show infinity when leads are open or not connected but it is showing 5.6Mohms on point 1 , 56Mphms on point 2 and infinity or some resistance showing on point 3 above defined.
How to calibrate it or how to solve this problem?
