• The ABS (absolute) sensor restores the last origin position automatically when the indicator is turned on.
    Note: Regarding origin setting, refer to “Origin Setting of Digimatic Indicators” on page F-18.
  • Thanks to Mitutoyo’s ABSOLUTE Linear Encoder, reliability has been increased due to elimination of over-speed errors.
  • Tolerance-judging measurement is available by setting upper and lower limit values.
  • Battery life of approx. 7,000 hours in continuous use has been achieved with only one battery.
  • Equipped with a data output port that enables incorporation into measurement networking and statistical process control systems.

Standard Digimatic Indicator

Large LCD
The large LCD incorporates 11mm characters giving 1.5 times the character area of conventional products (which
display 8.5mm characters) making measurement values much easier to read.

Standard Digimatic Indicator

Three large buttons
The popular three-large button design, which is used in products such as the ABS coolant proof Digimatic indicators ID-N/B, makes buttons easier to press and operations easier to perform.

Standard Digimatic Indicator

330º rotary display
The display can be rotated 330°, allowing use at a position where you can easily  read the measurement  value.

Standard Digimatic Indicator

Calculation: f (x) = Ax
Mounting the ID-CX on a measuring jig and setting the multiplying factor (to any practical value) allows direct indicationof size (see example below) without using a conversion table  and so improves measurement efficiency.

Standard Digimatic Indicator

Function locking
Ensures reliability of measurement by locking the settings to prevent preset function settings from being changed by mistake.

Standard Digimatic Indicator

Note 1: Dimensions of the inch (ANSI/AGD Type) dial indicator partly differ from those of the metric (ISO/JIS Type) indicator.
Note 2: Inch (ANSI/AGD Type) dial indicators are provided with a stem of 3/8″ dia. and #4-48UNF thread mount for the contact point.
Note 3: Products with an Order No. suffixed “B” have a plain back, and other models have a center lug back.
Refer to page F-55 for details of the backs.
