Readout Operations
Clear Key
Use the CLEAR key to erase digits that you entered by mistake, or to take you back if
you’ve pressed a wrong function key.
Absolute and Incremental Displays
Absolute Display
Shows the distance from your current position to absolute zero.
Incremental Display
Shows the distance from your current position to incremental zero. An incremental
zero is set when you preset a dimension, or when you zero the incremental
display.
Automatic Display Switching
Sometimes the readout will switch from one display to the other automatically.
When you enter a preset, for example, the display switches to the incremental
display so that you can move to zero. Whenever the readout does an automatic
display switch, INCR will appear briefly in the display.
