Hello, I found these two videos describing HV proble design for a DMM.
1.
2.
1. Uses 200M and 200K resistors
2. Uses 2x 20M and 40K resistors (the 40K is under rated should be like 2W)
Questions:
What is the better probe design? The 200M resistors are expensive and hard to find. So the second design is way better to me. Also it uses resistors on both wires meaning you can't mix wires.
