ABSOLUTE Digimatic MicrometersSERIES 227 —with Adjustable Measuring Force• Digimatic micrometer dedicated to applications requiring a constant/low measuring force such as measuring wire, paper, and plastic/rubber parts.• Ratchet mechanism in the thimble applies constant force to workpiece. • Compact and easy to handle. • Measuring force is adjustable (in steps) to suit various kinds of workpieces.• High-accuracy measurement can be performed even by unskilled operators due to the repeatability of the automatically applied measuring force. • Non-rotating spindle.• Measuring faces: Carbide.• In addition to standard specication, a non-rotating spindle type tooth thickness micrometer (refer to page B-33 for details) is also available.SPECIFICATIONS MetricOrder No.Measuring force (N)Range (mm)Resolution (mm)Maximum permissible error JMPE (µm)Measuring force (N)Accuracy of the selected measuring force* (N)Repeatability of measuring force* (N)Mass (g)227-201-200.5 - 2.5 (adjustable) 0 - 15±2 0.5, 1.0, 1.5, 2.0, 2.5± (0.1+ the selected measuring force/10)within 0.1300227-203-2015 - 30380227-205-202 - 10(adjustable) 0 - 100.0012, 4, 6, 8, 10± (0.4+ the selected measuring force/10)within 0.4345227-206-2010 - 20425227-207-2020 - 30415* These values are guaranteed when micrometer is used in a horizontal orientation (within ±3 degrees)Inch/MetricOrder No.Measuring force (N)Range (in)ResolutionMaximum permissible error JMPE (in)Measuring force (N)Accuracy of the selected measuring force* (N)Repeatability of measuring force* (N)Mass (g)227-211-200.5 - 2.5 (adjustable) 0 - 0.60.00005 in/ 0.001 mm±0.00010.5, 1.0, 1.5, 2.0, 2.5± (0.1+ the selected measuring force/10)within 0.1300227-213-200.6 - 1.2380227-215-202 - 10 (adjustable) 0 - 0.42, 4, 6, 8, 10± (0.4+ the selected measuring force/10)within 0.4345227-216-200.4 - 0.8425227-217-200.8 - 1.2415* These values are guaranteed when micrometer is used in a horizontal orientation (within ±3 degrees)Constant-Measuring-Force Mechanism Measuring force is generated by the action of trapping a workpiece between the spindle face and the anvil. The constant-force unit applies the specied measuring force. When the preset measuring force is reached, the count on the LCD is automatically held and the hold symbol appears. (To cancel the hold, reverse the thimble more than 1/10 revolution and press the hold button.)MicrometerThe origin of Mitutoyo’s trustworthy brand of small tool instrumentsProducts equipped with the measurement data output function can be connected to the measurement data network system MeasurLink® (refer to page A-25 for details).227-201-20227-205-20
