Hey All,
?
I'm looking at an 8402B calibrator, and the manual says that the measurements need to be done with a floating DMM that has a greater than 100Mohm input impedance.
?
The manual says to use an HP 740B - I don't have one of these, so I'm thinking of using an HP 34401A with an OpAmp Voltage Follower to buffer between the 8402 and the 34401.
?
Has anyone done this before and could provide any insights?
?
Thanks,
TonyG
