Count Direction
This determines which way is positive. Move each axis in the positive count
direction. The display will show a 1 or a 2 depending on count direction. You can
change the count direction by pressing the lower
ZERO key.
Encoder Resolution
Move each encoder until the readout senses and displays the resolution. You
shouldn’t have to move more than two inches. For encoders without Position-Trac,
press the lower
ZERO key repeatedly until you see the resolution you want.
Radius/Diameter
You can set either axis (or both axes) to display diameter readings when the RAD
DIA
key is pressed. Use the lower ZERO key to allow (display = 1) or disallow (display =
0) diameter display.
