With this utility you can make measurements on the quilt and 
calibrate the sensors.

All the measurement displays are reset to zero when you enter this 
screen.

The X and Y position windows show the position of the needle relative
to the point where the Reset X,Y button was touched.

The Length window shows the spatial distance of the needle from the 
Reset point.

The Area window shows the area of a rectangle which has sides equal
of the X and Y distances. If you touched the Reset X,Y button at the 
upper left corner of a rectangular pieced block, the Area window will 
show the area of the block when you move the needle to its lower 
right corner.

The Total Length window shows the accumulated travel of the needle
after consecutive resets. You can measure the circumference of an
irregular area by moving the needle around its boundary and touching
Reset X,Y along the way.

You may find that the displayed numbers don't match measurements
by a tape measure. This may be the case after changing the O-rings
on the sensor wheels. You can recalibrate the system by touching
[Calibrate]. The prompts on the screen will guide you through the
calibration steps. You should be able to mark 24 inches horizontally
and 12 inches vertically, and move the needle to this point.
If you touch [Reset] inside the message window, the factory default
calibration will be reloaded.

Touch [Finished] when you want to return to the Utilities menu.
