Anyone got a FLUKE T+ PRO Electrical Tester?

Relative mode should zero the meter if it has that function.
If you ever forget it is there, troubleshooting is going to take a lot longer.
I have one on order, so I will know for sure soon.

If you plug a SV225 into a Fluke 87V for instance and select resistance instead of showing the normal OL when leads are apart, it shows a little over 3K. Touching probes and using REL will zero it but automaticly locks you into manual 6.00 ohm range and you can't change the range.

OOPS!!
I was thinking about that more as I was driving home. I came to another conclusion also. If you manually selected the range first, then zero the meter it would still be worthless on readings much over over 3K because that is now the top of the scale. We are back to using Mivy's formula now.

Conclusion: SV225 is not recommended for use on resistance readings.

Yes, that's exactly what happens, instead of OL with testleads apart, it reads 3K. For example, set range to 60K, REL'd it with the SV225 installed and a 11K resistor read 2.4K!
