I had watched a recent video Dave made on a returned meter with a similar problem with OP's.

Cant do it. No one can. Whats the point of this conversation ? No point.

The Shannon ST42 LCR Tweezers have adjustable voltages and frequencies, which might work in your situation.

Good LCRs typically allow for adjustment of test voltage. As I said previously, you need to know the correct tools for the job, and how to use them, rather than trying to force an apple to be an orange.

The R (in LCR) stands for Resistance, and the ST42 can do Rs, Rp, Z, ESR, and Rdc. The ST42 voltage is rated at maximum 1Vpp, which means about 350mVrms. Test frequencies from 100Hz to 10kHz.


ETA: Since what you really need is an LCR, if you also need graphing, you'll need to spend more. Either a bench LCR with ethernet, or a HH LCR with BT. But you can also use some LCRs with TestController software, which will allow all sorts of graphing.

I understand the problem measuring resistance on a live circuit, i never said thats what i was doing.
I also understand measuring 10k resistor in circuit will give reading effected by other components and not 10k.
The reply count has gotten out of control so people start to make way too many assumptions so as a reminder, most multimeters will measure OK while fluke wont.
I am simply looking for a meter that has what i need that will measure resistances same way other Chinese no name junk does. It seems to be consistent across most of the chinese brands while premium products have different readings.

This wasnt even about the reading, it was about features.
At this point i give up on the search and shift focus to FLUKE firmware hack because there is no other way to fix it.

I never suggested you were measuring a live circuit but rather that your are just ignorant when it comes to their use.   

I doubt you would ever read this, but for others, this is a book on the basics of in-circuit testing.

Have you asked Fluke about your problem?  It is possible that you will get an answer sooner.
