Hi David,
Thanks for reply - the resistance side is also very inaccurate. I agree this will point to either:
- the dial has slipped on the shaft
- one or more components are now wildly off there stated tolerance.
Yes, the manual does not give much help as its one of the few that I have seen that doesn't indicate any component values. Furthermore, there several versions of this model and it appears that the unit became refined over time and this isn't reflected in any schematic! I have recently purchased a 2nd Hunts tester which I can compared this one to. But as I indicated in the previous sentance, the 2nd tester has a serial number of 177 and the one that is out of spec is no 3611 so I have a feeling that the circuits/components will not be the same.
Pity really as it looks so nice when its powered up and working!
Regards
Rob
