Digital or dial indicator on height gauge

[metric_taper]

Thank you, your video of making depth measurements, will be handy. I don't know how many times I've had to figure out relative measurements. Doing this, they can be drawn to an absolute coordinate system, with must faster capture time.
Most of the job of making a repair part is measuring the sample. This technique had not occurred to me.

I see a cable with 4 wires coming out of the indicator. Did you have any luck with an oscilloscope figuring out how to decode the data and clock?
