RE: Need a probe for Sencore SC61/3080 part # 39G294

Good luck as they're unique to Sencore... and there always to be more 'scopes than probes...

You may know this, but it might of interest to others... the probes are special, having two voltage dividers - one for the 'scope input, one for the voltmeter. And they're rated for 2000V... higher than most.

The divider for the 'scope input is the usual 9 megs with compensating cap, giving 10:1 attenuation with the 1 meg input. So any 10:1 probe should work, though it may not have the voltage rating and won't work with the DVM readout. There's also a 13.5 meg resistor connected to the tip which goes to a mini-banana plug for the DVM input. You could make up a series string of five 267K 1% resistors (make sure they're rated for at lest 500V!) and put it inside a regular meter probe for a separate DVM probe.
