Hi. Do you know how to fix qm heigh gage 600 malfunction

Thanks a lot. I don’t have a user manual for this model: QMH-350(14”) ORDER NO: 518-221 But this video gives useful information and save my time.

I would have liked to see how to go from a datum to the center of a circle

Thanks! about to start a new job on Monday and this helped refresh my skills. Excellent video :)
