Fluke 185 Review

<< < (7/17) > >>

Wytnucls:
Good show. Should be an easy fix, if the ADC was not affected. Waiting for your final assessment.

mimi123:
I fix it with one IRF3205 I have here and the old original mosfet that survive.

I have found the mosfets at Mouser but now I don't need other components and the shipping cost is too much. I will order later.

I think it's working right but I don't have a better multimeter to test it. |O

The measure is correct in both polarities. I think with a positive current is working one mosfet and with negatives the other.

I take some photos. All meters are in series.

With a positive current :



And with the probes reversed :




A good meter no doubt. :-+


BTW and for if someday is needed, do you have the program or the instructions to enter into the calibration mode?

All the best!

Wytnucls:
Replacing a MOSFET shouldn't need calibration, as it is just used as a switch.
Calibration is performed through the IR port, with 5520A calibrator. Sorry, I don't have the exact procedure for the calibration mode.

Wytnucls:
The service manual is on post #2 already.
The calibration manual was also posted earlier, but it doesn't tell you how to set up the meter for IR calibration.

Whoops, didn't notice that.  |O  I will delete my other post.
