Keys

• ON/OFF.SET key: Powerswitch. DATA set.
• ABS/INC UNIT key: Absolute & relative measuring, Metric/inch conversion.
• Zero key: Set current position as "0"

LCD Display

• "INC": Indicates relative measuring mode.
• "in": Indicates inch unit.
• "mm": Indicates metric unit.

Operation

Two ways of pressing the keys are used:

• (1) Press and release
• (2) Press and hold (2 sec. or more)

1. ON/OFF key:

• Press and release: Power on/off.
