Yep, there is a live demo for ya

I guess there is no other way to say this, but even though you have mad repair skills, you probably need to hit the electronics books a bit...

All i need to know is if there is any way to hack the device internals so it would obey my will. I think firmware driven device can be hacked by altering the firmware.

Oh, but adding a resistor to your test probe was too much to ask for? Come on now, you've run this train off the tracks...

FWIW, in your video when you are showing the "wrong" reading of 218 ohms, the applied voltage is about 210mV so too much voltage isn't really the issue. Clearly this circuit is non-ohmic and is reacting to the different test currents being applied. You were correct when you said "I really don't understand how this meter works". Even If you could modify the firmware, what would you program it to do?

Even though you may be good at what you are doing, you also clearly have no idea exactly what it is that you are doing and no inclination to learn. You never responded to my suggestions even though your video shows you already tried some of them. Why waste our time?

It would match the current of a chinese meter.

I am not wasting anyone time here who isnt willing to waste it including my self.

Why do you want to hack it? The Fluke doesn't do what you want. Not measuring resistance correctly, not displaying correct AC voltage, not having live trend. Just sell it and buy something else. It's still worth good money.

Why does Fluke start the resistance measurement from the Ohm measurement range? why not from highest MOhm to lowest Ohm?
Got it. :-+ It was in continuity check mode. Should it have shown something other than 0.00 in the MOhm measurement range?
