The Mitutoyo Series 293 is a large Digimatic outside micrometer series available in sizes up to 500 mm. Designed for precision measurement of large workpieces, it incorporates carbide-tipped measuring faces and a ratchet stop mechanism ensuring a constant measuring force. All models feature built-in measurement data output capabilities for seamless integration with SPC systems, spreadsheet software, and external applications via optional communication cables or wireless systems.
- Ratchet Stop Mechanism: Provides constant measuring force for repeatable and consistent readings.
- Carbide-Tipped Measuring Faces: Delivers enhanced wear resistance and durability.
- Measurement Data Output: Equipped with an output port to transfer measurement data to Statistical Process Control (SPC) systems.
- Position Detection: Utilizes an electromagnetic rotary sensor.
- Auto Power ON/OFF: LCD display turns off automatically after approximately 20 minutes of idle time while retaining the reading and measurement mode; turning the spindle restores the display.
- Error Display & Low-Voltage Alarm: Built-in safeguards prevent erroneous readings during LCD overflows or computing errors, and a low-battery indicator warns when voltage drops.
- 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 sets the display to zero at the current spindle position (incremental mode); a longer press resets to ABS measuring mode.
- Hold Function: Freezes the current display value for visibility in hard-to-reach measurement locations.
- Function Lock: Locks the PRESET and ZERO functions to prevent accidental resetting.
