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

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. |
