I suppose the easiest way would be to chuck a drill, move to some arbitary position and zero the DROs then move the Z down to drill a hole, move it up then command a few X and Y moves via the MDI line then lastly command a X0 Y0 move and then move down on the Z and see if your drill is in the same position, it will be surprising how accurate that will be as you will soon see if you drill new material.
To test for Backlash you could mount a clock (DTI)on the table and move it in one axis so its against the spindle, Zero Machs DRO and put jogging into step mode and setp away in the opposit direction until you see the needle move, the DRO in Mach will be reading the amount of backlash you have. You will need to repeat for each axis.
