Small Tool Instruments and Data Management

Compact design equipped with constant andlow measuring force mechanism in the thimble

*1
Quick
20 times fastermeasurement feed rate

Digimatic micrometer dedicated toapplications requiring a constant/low
measuring force such as measuring
wire, paper, and plastic/rubber parts.

Speedy spindle feed of 10 mm per thimble rotation that enables
widely differently sized features to be measured quickly.
*1: Compared to standard micrometers (0.5 mm per revolution).

Function locking prevents misoperation!
Above: 2 to 10 N type
Below: 0.5 to 2.5 N type

Constant-Measuring-Force Mechanism

Function lock enhances usability by preventing the origin from being
accidentally changed during measurement.

2)

1)Battery cap can be easily opened
3)1) Measuring force is generated by the action of trapping aworkpiece between the spindle face and the anvil.
2) The constant-force unit applies the specified measuring force.
3) 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.)

Extended battery life
Low-power electronics have extended the battery life to 5 years innormal use*2.
*2: Typical, assuming average frequency of use and normal applications.

Absolute scale
The ABS (absolute) linear scale eliminates
the need for origin point setting at every
power-on and achieves high reliability while
being free from overspeed error.

2The groove in the battery cap has been increased from 1.8 mm to
2.4 mm in width to enable the cap to be more easily opened.

Connectable to MeasurLink
Connected to MeasurLink, "visualization of quality" can be achievedby enabling real-time data collection, global control and statisticalanalysis.

Products equipped with the measurement
data output function can be connected to themeasurement data network system MeasurLink

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.
Pressing the HOLD button freezes the current value

can be recorded.

the reading and measurement mode are retained. Turning the spindle causes the reading toON/OFFreappear.

Error alarm

In case of an overflow on the LCD or a computing error, an error message appears on theLCD, 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.
