If you are asking if there is a way to simulate a press on the "zero" key using the 3 wires, then the answer is:
(to the best of my knowledge) the communication is only one way: from dial indicator to some device, so no.

You could just simulate a tare button is software
or connect directly to the "zero" button (solder some wires) - but the second solution is probably not worth it
