The gauge is in a position so that you can check the pressure as you go, from 0 to 60 PSI with 1 PSI Increments. To check pressure while deflating, use the quick release coupling to allow the gauge to read the pressure at any time.

This is not intended to be used as a regular tire pressure gauge, as the fitting must be screwed on to the tire valve. It can be done, but would not be as fast as using the Digital Tire Gauge that comes with the Dobinsons 4x4 Tire Repair Plug Kit, Part TR80-3809 (sold separately).
