This key begins a preset operation on the Y axis for a mill or the Z1 axis for a lathe.  See the operation section for more detail on how to set a preset.

Z Preset

This key begins a preset operation on the Z axis for a mill or the Z2 axis for a lathe.  See the operation section for more detail on how to set a preset.

X Zero

This key is used to set either an incremental or absolute zero on the X axis.  For detailed information on setting axis zeros, see the operation section.

Y Zero

This key is used to set either an incremental or absolute zero on the Y axis for a mill or the Z1 axis for a lathe.  For detailed information on setting axis zeros, see the operation section.

Z Zero

This key is used to set either an incremental or absolute zero on the Z axis for a mill or the Z2 axis for a lathe.  For detailed information on setting axis zeros, see the operation section.

Numeric Keypad

Numbers are entered into the DRO via the numeric keypad.  It is used during preset and zero operations to enter offsets and is also used to enter information for function operations.  The set indicator is lit when the DRO expects the user to enter a number on the numeric keypad.

The ENTER key is used to finish number entry.

The CLEAR key is used to delete the right-most digit or decimal point or to exit numeric entry when all digits are cleared.

Decimal Point

This key enters a decimal point at the current position when entering a number on the numeric keypad.

The CLEAR key can be used to delete the decimal point if it is at the right-most position.  A second decimal point is used to indicate that the number entered is a factional number instead of a floating point number as described below.

Sign

The sign key toggles between a positive or negative value while entering a number on the numeric keypad.  It can be pressed at any time during number entry.

Clear

The clear key serves a variety of uses:

• During number entry, it deletes the right-most digit or decimal point.  If the number is a single zero, it will end number entry without entering a number.
   
• During setup, it serves as an abort key to not save the changed configuration.
   
• During functions, it serves as a backward key while moving through function steps.

Enter

The enter key serves a variety of uses:

• During number entry, it is used to finish entering the number.
   
• During setup, it serves as an accept key to save the changed configuration.
   
• During functions, it serves as the forward key while moving through function steps.

Absolute/Incremental

This key toggles between absolute and incremental modes for all axes.

Imperial/Metric

This key toggles between imperial (inches) and metric (millimeters) modes for all axes.

Function Key

The function key is pressed to display the function menu.  You can also press another key on the keypad as a speed key to quickly access a function rather than selecting it through the function menu.
