• Long stroke dial indicators with a ø57mm outer frame. All the models are equipped with limit markers and a bezel clamp as standard.
• An O-ring is employed to ensure air-tightness between the outer frame and the crystal case to prevent water or oil penetration.
• Both the stem and the spindle are made of high-strength quench-hardened stainless steel suitable for heavy-duty use.
• A carbide contact point is employed.
• The grand gear is made of stainless steel with high resistance to wear and deformation.
• Application of a hard coating on the surface of the crystal makes the gauge highly scratch- and chemical-resistant.
• The bezel clamp and lifting lever* (optional) can be attached to either the right or left side. These parts can be easily installed and removed without any tools.
  * Not available for waterproof type

FEATURES

• GO/±NG judgment function: If a judgment result shows an out of tolerance condition, the display backlighting changes from green to red.
• An analog bar indicator has been integrated to make upper/lower limit and turnover point reading more comfortable.
• With Mitutoyo’s ABSOLUTE Linear Encoder technology, once the measurement reference point has been set it will not be lost when the power is turned off. Also, reliability has been increased due to the elimination of over-speed errors.
  Note: Regarding origin setting, refer to “Origin Setting of Digimatic Indicators” on page F-18.
• Easy-to-read large LCD readout with the character height of 8.5mm.
• External power supply type: battery change is not necessary. Power can also be supplied via the AC adapter supplied as a standard accessory.
• The resolution can be switched between 0.001mm /0.01mm (or .001” /.0005”/.0001” /.00005”).
• Equipped with a data output port that enables incorporation into measurement networking and statistical process control systems.

Application
Difference/Runout measurement
Example: Indicator travel from points A to D
Difference (or Total Runout) is displayed as A. Dimensions B (maximum value) and C (minimum value) can be recalled from memory with a simple key sequence.

• This new-generation digital indicator offers the excellent accuracy and functionality expected
  from the top class of indicator.
• Take advantage of its high accuracy backed up by 0.5μm/.00002” resolution, remote control
  functionality via a handheld controller (or an RS-232C interface) and easy runout measurements
  with the well-established analog bar display.
• Functionality meets the needs of diverse measurement applications.

• With the optional remote controller, operations such as zero-setting and presetting can be made without touching the indicator body, thereby avoiding disturbance to the set-up.
• An advanced, remote control system can be implemented with the built-in RS-232 interface and a PC.
• Equipped with a data output port that enables incorporation into measurement networking and statistical process control systems.
