DIMENSIONSUnit: mmFunctions Origin point setting (ABS length measurement system): Pressing the ORIGIN button resets the ABS origin at the current spindle position. Origin values can be set depending on each size. Zero setting (INC length 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 when the instrument must be moved away from the workpiece before the reading can be recorded. Function lock: 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. Auto power ON/OFF: 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.Data output*4: 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 overow 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. *4: Only for the models with SPC data output Thanks to the quick movement, positioning times are reduced by 60%* and measuring times by 35%* compared with a conventional micrometer.*According to Mitutoyo’s comparison test data for measuring time on typical workpieces.SPECIFICATIONSMetricOrder No.RangeResolutionAccuracy*1FlatnessParallelismMasswith SPC data output293-140-300 - 25mm0.001mm±1µm1µm265g293-141-3025 - 50mm325g293-142-3050 - 75mm2µm465g293-143-3075 - 100mm±2µm0.3µm620gwithout SPC data output293-145-300 - 25mm1µm265g293-146-3025 - 50mm±1µm325g293-147-3050 - 75mm2µm465g293-148-3075 - 100mm±2µm620g*1 Excluding quantizing errorInch/MetricOrder No.RangeResolutionAccuracy*1FlatnessParallelismMasswith SPC data output293-180-300 - 1".00005"/0.001mm±.00005”.00004”265g293-181-301" - 2"325g293-182-302" - 3".00008”465g293-183-303" - 4"±.0001”.000012”620gwithout SPC data output293-185-300 - 1".00004”265g293-186-301" - 2"±.00005”325g293-187-302" - 3".00008”465g293-188-303" - 4"±.0001”620g*1 Excluding quantizing errorRangeLa b 0 - 25mm06.52525 - 50mm257.332.550 - 75mm5010.14775 - 100mm7511.560(Spindle diameter)63.648.5aø6.35L Minimum measuring ( length )25210.82.5ø6.3(Measuring face)ø6.3(Measuring face)bø19.3293-141
