how do you calibrate it?

Calibration is not needed as far as I know

Placing on diamonds and having no response, what does that mean?

I have used this unit and had the same response on known diamonds. Sometimes the stone is dirty and needs a cleaning. This can throw off results. Also, my unit is getting returned when I have a suitable replacement. It sometimes takes 3 or more tries to get it to register. Clean the stone and try touching it with a firm but not point grinding pressure a few times and if it doesn't work try another tester. Assuming of course you know the diamond is real.

How can I get a replacement tip?

You can get it replaced from manufacturer, fill out the return form.
