## Questions & Answers

**Q: 1.What is the measure range (insul-resistance), at voltages (250/500/100V)?  2. What is the resolution of measured resistance at above ranges?**
A: Dear Sir,
         Kindly refer your message, Voltage Range can measure : 250VDC (0.25MOhm to 400MOhm); 500VDC (0.5MOhm to 4GOhm); 1000VDC (1.5MOhm to 40GOhm)

Regards
Sunil Associates

**Q: how many test can be carried out by 1 set of new battery**
A: Dear Sir,
         Kindly refer your message, in the instrument we provide AA 1.5V Alkaline battery which have much higher current capacity as compared to the normal battery. Also it depends upon the test you carry on your sample. If you do testing 5 to 10 min on one sample then the output will vary as compare to normal testing.

**Q: Is there any warranty on product .**
A: Sir, it has 6 months warranty against manufacturing defects.

**Q: Can we use it for testing 11Kv or 33kV High tension line fault testing ?**
A: Yes you can check the insulation of your sample.
