Calibrating a co-axial indicator...

[TheCalibrator]

I'm wondering if anyone knows a way to calibrate a co-axial test indicator.
Specifically this one:

I'm in charge of calibrating nearly everything in the machine shop where I work.
Recently, one of the employees bought one of these and I need to figure out how to calibrate it.

If all else fails (assuming no reference materials with the gage or available online), contact the manufacturer for calibration methods or services they may offer. If this piece of equipment needs to be traceable, that would definitely be my starting point as the initial feel I get from your post is that you probably do not have any appropriate references to work with. You could also set up a side by side test with a known calibrated gage to check performance over its range or intended use range.
