The 3458A is an amazing meter with the worst manual ever. It's almost as though the manual was written by a lawyer.
I want to make ACV, DCV and resistance (4 and 2 wire) measurements from about 25ft away. (No Current measurements)
What would be the best way to make the connections?
The 4 connections obviously must go to the device being measured, HI, LO 2 wire and HI, LO 4 wire. After that is were things start to break down for me. The cable is going to be in a noisy environment and I would like to shield it. Where do I connect the shield? Do I connect the shield at the meter or at the device being measured?
Is the shield separate from the Guard or is the shield the Guard?
