Robert Muth All Messages By This Member #150038 Hi Jim, No, I have not been successful yet. I've attached pictures of both knobs. In case the attachments don't go through, the clear flange on the Volts/ Division knobs are marked 5, 10, 20, 50 mV, then .1, .2, .5, 1, 2, 5, 10, 20, 50, 100, 200, 500 V. the red cal knob button does have a black band and face. I have both red cal knobs. The phenolic is broken on both Volts/ Division knobs and one of the shafts for the red & black knob is missing.

[email protected] All Messages By This Member #150040 Sorry I don't have any that go up that high on the volts scale only to 50 I don't know if you could detach the clear ring from the knob part and reglue another knob onto it I have knobs in good shape with the black ring inside the front opening I probably have a shaft also just need the length have a bunch of different lengths.

Robert Muth All Messages By This Member #150041 Thanks for looking Jim. The 100, 200, 500 V marks are for a 100x probe. I'll open my 485 up this weekend and check the shaft length and see if I can detach the ring.
