Ultra-high Accuracy Digimatic Micrometer 293-100-20
•The flagship model, featuring unparalleled high accuracy and resolution.
•Maximum Permissible Error (JMPE) of±0.5 μm is achieved with our innovative
0.1 μm resolution ABS (absolute) rotary sensor and screw machining technology
Highly rigid frame and high-performance constant-force mechanism allow stable measurements.
•Body heat transferred to the instrument is reduced by a (removable) heat shield, minimizing the error caused by thermal expansion of the frame when performing handheld measurements.

Preset (ABS measurement system):
The measurement origin can be preset to any value within the display range for convenience in measuring.
Zero-setting (INC measurement system):
The display can be zeroed at any position of the spindle, making comparison measurement easier. Returning to the absolute-measurement mode is easily accomplished.
Hold:
The function that holds the display of value is useful when it is difficult to see the measured value at the measurement point. When the function is cancelled, the previous zero-set point or a measured value with reference to the origin is displayed.
Resolution switching:
The resolution of the display can be switched. If 0.1 μm measurement is not required, the resolution can be switched to 0.5 μm.
Function lock:
Functions such as preset or zero-set can be locked to avoid inadvertently changing the origin position.
On/ off:
The power can be turned off after measurement is complete. Even after the power is turned off, the origin or last zero-set position remains in the memory.
Auto power off:
Even if the power is left on, the power turns off automatically if the micrometer is not used within a 20-minute period.
Measurement data output:
Measurement data can be output, allowing easy incorporation of this instrument into a statistical process control or measurement system.
Error alarm:
In the unlikely event of a display overflow or calculation error, an error message is displayed and measurement stops. Measurement cannot continue until the error is corrected.
Also, if the battery voltage drops below a certain point, the battery indicator will turn on before measurement becomes impossible, warning the user that the battery needs to be replaced.
