What is the procedure for calibration?

you can contact our customer service for the procedure. Just to remind that recalibration requires professional equipment and we recommend to by performed by accredited lab. failure during re-calibration process will cause item inoperable and warranty not cover misuse.

does it have, peak torque read out? Meaning, highest torque reached displayed for a few seconds, as one comes off the bolt/nut they just torqued.

Yes, this holds the highest torque reading until you start loading it again.

Might be a dumb question, but how do you know if it's properly working? I just broke a screw set for 1.7nm

Easiest way is to test it against a known mechanical torque bar. As long as it was not damaged in shipping it should be fine out of the box.
