 Technical Data

• Measuring force: 7 to 9N
• Power supply: Lithium battery (CR2032) x 1
• Battery life: Approx. two years when used under normal conditions

• 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  The displayed value is held while the spindle is withdrawn
  and the micrometer moved so that the display can be
  read at the operator's convenience. After cancelling the
  hold, the instrument returns to the previous measuring
  mode (absolute or incremental).
• Resolution switching:
  The resolution of the display can be switched. If 0.1μm
  measurement is not required, the resolution can be
  switched to 0.5μm.
• 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.
