MITUTOYO SERIES 293 QuantuMike Micrometer

Accurate and highly environmentally resistant, assisting with many types of measurements
Ratchet thimble provides better operability for one-handed operation.
Oil-resistant material used for all plastic parts.
Models equipped with a Digimatic output port can form part of a statistical process control or networked measurement system.

Functions

Zero-setting: A brief press on the ORIGIN button sets display to zero at the current spindle position (zero-setting), which allows easy comparison measurement.
Auto power ON/OFF: The reading on the LCD disappears after this instrument is idle for about 20 minutes, but the reading is retained.
Turning the spindle causes the reading on the LCD to reappear.
Error display: 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-voltage alarm indicator appears well before the micrometer becomes unusable.
