... If you can't repair the old probe, you could replace it with your own. For simplicity, I suggest making two non-switchable probes rather than attempting to...
I found a Heathkit 'Science Series' Electrical Workshop box in my basement. It's in nice condition, probably better than 8 out of 10. It's the BOX ONLY; I can...
I found the answer to my "problem" in a copy of the probe assembly sent ,to me , and for that I'm grateful. !!! thanks to all who responded . !!! carl / kz5ca...
Somewhere, I saw an augment for not moving the resistor to the body of the instrument, something about the Lead to the Meter? I will have to do some research...
You do NOT want to move the resistor to the inside of the meter. One major purpose is to keep the capacitive loading minimal. With the resistor in the probe,...
Ken - Do NOT move the resistor inside the meter. Heath's (and all other VTVM manufacturers) had a reason for making the complex switching probe to put the...

Thanks to all that replied, including those that sent me schematics. Is the "W" something used in later years? I don't recall seeing any SBW-101's or such....

It's simple enough. Measuring DC, the 1M resistor in combination with the proble cable capacitance act as a low pass filter, attenuating EMI. This is important...
