Morning to all the good people out there.
When insulation resistance testing using Megger MFT 1710, sometimes the value never get to >999, it will keep rolling over random numbers and never settle which i do for about 15-20 seconds and give up. I may expect to see this on older cable but i've been getting this on new cable, 1.5mm & 2.5mm.
I got the megger with the 7 week C&G course i did, so im now starting out and learning in the real world
Could anyone tell me if this is normal?
Should it settle on a measurement?
How long should I do the IR test for?
What measurement should i enter on the cert?
Thanks in advance to all who reply
