MITUTOYO SERIES 293 DIGIMATIC MICROMETER (300-500MM)

  • This large Digimatic micrometer series is available in various sizes up to 500 mm. It features a ratchet stop for constant measuring force.
  • Measuring faces: Carbide tipped
  • All models have a measurement data outout function that is useful for measuring large workpieces. This function allows you to easily send data via an optional communication cable or wireless system and import it to spreadsheet software or use itin various applications.

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 display: 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.
