Using our unique processing technology, we have produced a highly accurate,high-lead screw for the slim spindle. Unlike a typical micrometer with a 0.5mm screw lead, the thimble moves the spindle 2.0 mm in a single rotation,
allowing for rapid measurement. Because the spindle can be released by alarge amount with just a small amount of rotation, it is ideal for cases such as
when various dimensions need to be measured.

High accuracy measurement of ±1 μm

Ratchet thimble mechanism for stable measurement

With a maximum permissible error (J mpe) of just ±1 μm*,
QuantuMike is suitable for workpieces that require increasingly
high accuracy.

The micrometer features a ratchet thimble mechanism that allows stable measurement to beperformed, even when operated one-handed. Ratcheting works with both the thimble and thespeeder. The sound of the ratchet allows the user to verify the certainty of operation, and thespeeder ratchet is convenient for rapid spindle feed.

Ratchet thimble mechanism

Can be used in environments where
there is water, oil, or dust
The micrometer achieves
protection level IP65 forwater-resistant and dustresistant performance. It can beused with confidence even atsites where it may be splashedby coolant liquid.

The micrometer determines whether the measurement value is within the upper and lower limits of tolerance and displays a tolerance judgment mark. The user can judge pass/
failure at a glance.
Also, using the calculation function, it is possible to calculate correction values ​​for a processing machine from the measurement results. This eliminates the potential inconvenienceof calculations and prevents human errors such as confusing plus and minus values ​​when entering correction values ​​into a processing machine, thereby contributing to thereduction of processing defects.

Measurement Data Management System

In addition to Digimatic d1/d2 (output), support is also provided for Digimatic S1 (input/output) communication. Bidirectional serial communication enables easy setting andmanagement of Digimatic gages. Individual management of Digimatic gages can be performed from a PC, and settings can also be changed. The same settings can also be
applied to multiple Digimatic gages.
*An optional cable and measurement data input unit are required for bidirectional serial communication (see page 7).
Please note that this cannot be used with the U-WAVE series. Additionally, USB-ITPAK V3.0 must be installed on the PC being used.

Error message

In the event of an overflow on the LCD or a computing error, an error message appearson the LCD, and the measuring function stops. This prevents continuation ofmeasurement with an erroneous display. Also, when the battery voltage drops to acertain level the battery depletion indicator appears well before the micrometer
becomes unusable.
