Functions

Origin Point Setting (ABS measurement system)

Resets the ABS origin at the current spindle position to the minimum value of the measuring range and switches to ABS mode.

Zero-Setting (INC measurement system)

A brief press on the ZERO/ABS button sets the display to zero at the current spindle position and switches to the incremental (INC) measuring mode. A longer press resets to the ABS measuring mode.

Hold

Pressing the HOLD button freezes the current value in the display. This function is useful for preserving a measurement in situations of poor visibility where the instrument must be moved away from the workpiece before the reading can be recorded.

Auto Power Off

The reading on the LCD disappears after this instrument is idle for about 20 minutes, but the reading and measurement modes are retained. Turning the spindle causes the reading to reappear.

Data Output

Models equipped with this function have an output port for transferring measurement data to a Statistical Process Control (SPC) system.

Error Alarm

In the unlikely event of a display overflow or calculation error, an error message is displayed and measurement stops. Measurement cannot continue until the error is corrected. Also, if the battery voltage drops below a certain point, the battery indicator will turn on before measurement becomes impossible, warning the user that the battery needs to be replaced.
