Small Tool Instruments and Data Management Coolant Proof Micrometer QuantuMike Pioneering design, means taking the lead Bulletin No. 1930 Rapid measurement is achieved thanks to 2 mm* of spindle feed for every thimble revolution! * l Patent registered (in USA) l Patent pending (in Japan, Europe, and China) Coolant proof micrometer Debut of next-generation micrometer delivering thanks to integration of cutting-edge technology Coolant proof micrometer Mitutoyo is proud to have reached its leading position in the micrometer market through a spirit of innovation, imagination and creating added value. The QuantuMike brand of micrometer, inspired by this Mitutoyo Spirit, provides users with an excellent measuring experience with higher speed, quality and stability than ever before owing to the integration of sophisticated manufacturing and processing technologies. The name QuantuMike is from Quantum and Micrometer, reflecting our belief this tool represents a quantum leap in micrometer ergonomics. The new global standard ······ QuantuMike Evolution since the innovation by James Watt in 17 History of micrometer advancement  1772 1937 Micrometer invented by James Watt (UK) Mitutoyo success in manufacturing micrometers performance far beyond users’ expectations y Rapid measurement Faster measurement is achieved by using a coarser thread which feeds the spindle by 2mm per revolution of the thimble instead of the standard 0.5mm. This increase in thread lead has been made possible thanks to new high precision thread-cutting and test techniques. Trials show that a reduction in positioning times of 60% and measuring times of 35%* can be obtained, compared with a conventional micrometer. * According to Mitutoyo's comparison test data for measuring time on typical workpieces.

The ratchet works from the thimble as well as the speeder so it is always easy to use - even when making measurements one-handed. The sound of the ratchet provides the user with a sense of confidence and the speeder enables the rapid spindle feed needed when measuring widely different dimensions. A statistical process control system and a measurement network system can be established to share quality information with a model equipped for data output. Dust/water resistance with IP65 protection level Excellent resistance against oil, water and dust enables this product to be used in machining situations that include splashing coolant fluid. *• Patent registered (in USA) Category Protection against human contact and foreign bodies Protection against water • Patent pending (in Japan, Europe, and China) Ratchet on thimble Ratchet on speeder Ratchet-induced microvibrations along the spindle help ensure repeatable measurements スピーダ部 ラチェット QuantuMike is equipped with a function lock feature to prevent the origin point being moved by mistake during measurement.

Please note that this certificate cannot be used to obtain a Certificate of Calibration because the purchase date cannot be specified. • Please let us know if a Certificate of Calibration is required when ordering a micrometer. This certificate is supplied, for a fee, and certifies the traceability of the purchased instrument and of the standard that was used to calibrate that instrument. • Certificates of inspection and calibration are issued after processing each instrument by special measuring equipment, developed using Mitutoyo’s advanced measuring technologies, which feature very small uncertainties of measurement.

A longer press resets to the ABS measuring mode. Pressing the HOLD button freezes the current value in the display. This function is useful for preserving a measurement in situations of poor visibility when the instrument must be moved away from the workpiece before the reading can be recorded. A second press unfreezes the display ready for another measurement. This function allows the ORIGIN (origin point setting) function and the ZERO (zero setting) function to be locked to prevent these points being reset accidentally. The reading on the LCD disappears after this instrument is idle for approx. 20 minutes, but the origin point is retained. Turning the spindle causes the reading on the LCD to reappear. Models equipped with this function have an output port for transferring measurement data to a Statistical Process Control (SPC) system. 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. 19.3 6.35 L 2.8 b a Error alarm Pressing the ORIGIN button resets the ABS origin at the current spindle position.
