Fantastic, Dewey. Thank you indeed.
I used to keep my umpteen watches in top condition as a user, but alas, I am no watchmaker. Back in the eighties, had a Certina LCD, their first offering. Set me back $500 or so. It had a trimmer spanning 20s/day, but this ran out and the crystal needed a few more pF to get zero beat with my radio signal. No space for a proper padder, so I made one by grinding off most of a 2mm ceramic cap and soldering leads to the remaining part. Did better than a second a week that watch! But it died of LCD blight after a few years.
More recently, ---- oh dear.
This vibrograf thing shows an uncertain 4 to 5V between black and red, and even more, 9, V to blue. Much too high? Must check if it drops sourcing several 100 uA.
All in all, not a great instrument. Will keep it though.
Thanks, again.
