HP 410B probe wire

KB2LMN All Messages By This Member #123107 I’m picking up a HP 410B but the probe wires are dried up and cracking. What’s the best type of wire to use? High Voltage Silicone??
saipan59 (Pete) All Messages By This Member #123109 I believe the most important feature of "probe wire" is that it have very fine strands, so that it doesn't break internally with a lot of flexing. And of course, the insulation needs to be appropriate to the peak voltage levels. Pete
Askild All Messages By This Member #123120 Hi, Some of these are screened? (caoaxial)??wires, but the screen is only connected inside the instrument, and not connected on the probe. So please check how many of them are coaxial.? Or maybe someone else has the correct answer.

n4buq All Messages By This Member #123121 COMMON and OHMS/AMPS is regular probe wire.? DCV is shielded (coaxial).? ACV is shielded with two conductors (triaxial).

Bob Albert #123124 Don't forget the resistor in the DC probe. On Tuesday, March 1, 2022, 05:00:07 AM PST, n4buq <n4buq@...> wrote: COMMON and OHMS/AMPS is regular probe wire.?

Bob Albert #123128 The 410C is different.? The 410B has regular wire for Ohms, Commnn, and (except for the resistor) DC.? Well the DC may be shielded (not coax).? The AC probe is fancier with filament voltage for the tube.

n4buq All Messages By This Member #123129 You're absolutely right about that.? I checked one of mine and OHMS/AMPS is, indeed, shielded.? Apologies for the misinformation.
