Assemble multimeter and measure the voltage from one side to the other of R241.

**Add The video forgot to measure the right side of R241。The left side of R241Z is -1.631V, the right side is -1.565V
Harry_22:
Perfect!
Now you have 10 times more resistance than before.

The video is uploading, it may take a while.

Unfortunately, I pressed "LOW RANGE ENABLE" and the analog pointer still swung.

In other words, I don't know if this 8920A host has other faults. I mean some faults that I don't know about yet.
Harry_22:
"Low Range" is quite sensitive.
Close the shielding cover and check it again.

Yes.

I am testing "LOW RANGE ENABLE" with the shield cover closed.
Open the shielding cover and press "LOW RANGE ENABLE" 8920a has no change
