1.
Set-up a gauge block or standard and indicate it parallel to the axis you are calibrating.
Note: Put the display in Inch or mm to match your gauge block. Recommended gauge
blocks are:
X and Y – 150 mm or 6”
Z -- 75 mm or 3”
2.
Set a 0.0001” indicator in the spindle and move it up to one side of the gauge block or
standard.
3.
Go to setup mode, go to section “B” and press CODE 123.
4.
Select the axis you want to calibrate X, Y or Z. For the quill press the F1 key labeled QUILL.
5.
Follow the instructions on the screen to complete calibration.

Backlash Compensation
Code 11: Set X or Y backlash constant
Note: this procedure is on systems with Scales only.
Go to setup mode, go to section “B” and press CODE 11. Refer to service code section for further
explanation.
Code 127: Set X or Y Backlash Constant
Note: this procedure is only for systems without TRAK Sensors or Glass Scales.
Every mechanical system has at least a little backlash, or lost motion. It is produced by the small
amount of play between the gibs and ways, and mostly by the accumulative bending or elasticity of all
the parts of the drive train under load. The backlash constant is factory set, but may need to be
adjusted periodically.
1.
Set a 0.005 mm dial indicator in the spindle, and touch off on a block or the vice along the
direction (X, Y or Z) you wish to check, or set the backlash constant.
2.
Turn on the ProtoTRAK and at the Main Menu, follow the procedure below precisely:
