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 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.
  • Function lock:
    This function allows the PRESET (origin point setting)
    function and the ZERO (zero-setting) function to be
    locked to prevent these points being reset accidentally.
  • Auto power ON/OFF:
    The reading on the LCD disappears after this instrument
    is idle for about 20 minutes, but the reading and
    measurement mode 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 case of an overflow on the LCD or a computing error,
    an error message appears on the LCD, and the measuring
    function stops. This prevents an instrument from giving an
    erroneous reading. Also, when the battery voltage drops to
    a certain level, the low-battery-voltage alarm annunciator
    appears well before the micrometer becomes unusable.
