[time-nuts] FW: Plugs on the FE 70E

Chuck -

Well, I can maybe see the justification on some sensitive instruments
measuring down to the nanovolts. However, here we are talking about a good
several volts, and low impedance, where the isolation, at least from what I
would surmise, would not be as critical. My 6 1/2 digit HP voltmeter only
uses banana jacks, but, it does give you a four wire (Kelvin) connection
capability if you want to use it. Well, at least some one has seen these
before. Where have I been all my life? -

Yep,

That is the same type used by HP and Keithley as input connectors on some
of their volt meters.
