Digimatic Micrometer Heads offer you perfect integration into machinery and measuring instruments where measurements are displayed on an easy-to-read LCD readout. Eliminate radial torsion on your workpiece with a non-rotating spindle tip (Only models 350-261-30 and 350-361-30). The Mitutoyo Digimatic digital micrometer head is manufactured with the same precision and durability as the Mitutoyo trusted micrometers in their Japanese factory. The frame and spindles on Mitutoyo’s micrometer heads are constructed of special hardened steel that minimizes flex and fluctuations due to temperatures for better, repeatable accuracy. The ratchet thimble provides a constant measuring force on the spindle to ensure accurate, repeatable measurements.

Functions of Series 350 Digimatic Micrometer Heads Include:

• 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 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
• Data Output Equipped with output port for transferring measurement data to a Statistical Process Control (SPC) and measurement system
• 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
• Error Alarm 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 indicator appears well before the micrometer becomes unusable
• 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
