Assemble multimeter and measure the voltage from one side to the other of R241. --- End quote --- **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 |

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. |

"Low Range" is quite sensitive. Close the shielding cover and check it again. |
