Speedy measurement is achieved thanks to 2 mm*of spindle feed for every thimble revolution!
(* Conventional model 0.5 mm)

Speedy measurement

Ratchet thimble mechanism ensures stable measurement

Faster measurement is achieved by using a coarser thread whichfeeds the spindle by 2 mm per revolution of the thimble insteadof the standard 0.5 mm. This increase of spindle feed 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 aconventional micrometer.

QuantuMike* According to Mitutoyo's comparison test data for measuring time on
typical workpieces.

Comparison of time needed to measure a 6-step cylindrical workpiece
One-handed measurement times when a 6-step cylindrical workpiece is measured successively from the smallest diameter.

0.5 mm

2.0 mmThe patented ratchet thimble mechanism* helps ensure repeatable
results by transmitting microvibrations along the spindle to thecontact face to provide a constant measuring force and encourage
good contact with the workpiece. The ratchet works from thethimble as well as the speeder so it is always easy to use - evenwhen making measurements one-handed. The sound of the ratchetprovides the user with asense of confidence and thespeeder enables the rapid
spindle feed needed whenmeasuring widely differentdimensions.

Origin point setting
Pressing the ORIGIN button resets the ABS origin at the current(ABS length measurement system) spindle position.
A brief press on the ZERO /ABS button sets display to zero at theZero setting
current spindle position and switches to the incremental (INC)(INC length measurement system) length measurement system. A longer press resets to the ABS
length measurement system.
Pressing the HOLD button freezes the current value in the display.
This function is useful for preserving a measurement in situations
Holdof poor visibility when the instrument must be moved away fromthe workpiece before the reading can be recorded. A secondpress unfreezes the display ready for another measurement.
This function allows the ORIGIN (origin point setting) function
Function lockand the ZERO (zero setting) function to be locked to preventthese points being reset accidentally.
The reading on the LCD disappears after this instrument is idle
Auto power ON / OFF 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
Data output
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.
Error alarm
Also, when the battery voltage drops to a certain level thelow-battery-voltage alarm annunciator appears well before themicrometer becomes unusable.
