• Enables a tolerance judgment to be output to external equipment for a measurement result against user-defined limits. Solid-state switching provides high reliability by avoiding metallic switch contacts.
• Output is enabled by directly connecting to external devices (sequencers, etc., for which a logical invert is available if required). The measurement and judgment results are displayed on the LCD. The judgment result is also indicated by 2 LEDs.
• A peak-detection function is equipped for measuring and judging peak values, such as runout.
• Measurements are absolute (ABS system) relative to an origin point*1 as set by the user, which holds indefinitely so does not require resetting at every power-on.
• Provided with a 4m cable.
• External power required is 5 – 24VDC.
• Dust-water protection level: Conforms to IP54.

* Flat back only
Inch/Metric

* Flat back only
Note: All instruments in this series are of the flat back type.
The back is interchangeable with the standard backs for Series 2.
Refer to page F-55 for details of the optional backs.
*1 Does not include quantizing error (±1 count). Valid for resolution set to 0.001mm/’.00005″ and coefficients A=1, B=0 and C=0.
*2 Applies only if not connected to a data processor. Battery life depends on use of the indicator. Use the above value as a guide
only. (TIP) Battery life with Peak detection mode and FAST mode ON is about 10 months.
*3 Applies for a spindle orientation between the spindle pointing vertically downward to the spindle horizontal.
*4 The resolution can be selected from one of 12 steps (Refer to table right).

DIMENSIONS

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.

Fixture examples

Examples of measuring various features 

* The spindle position at which the ORIGIN is set. This is when the contact point is touching either the reference plane or the calibrated artefact, as shown.
** The ‘Err30’ message shown in the display is extinguished when the spindle is moved into the measurement range.
*** The value of d is chosen to suit the radius range to be measured, the stroke of the indicator and the best spindle position for the ORIGIN. Note that the value of x’ should not be allowed  to approach zero as this is a highly non-linear region of the equation and measurement accuracy will deteriorate rapidly. A spreadsheet simulation will aid selection of the best value of d for particular r, L and R values.
Notes
1. Fixtures suited to individual workpieces can be made to order.
2. Measuring accuracy is subject to fixture accuracy and workpiece form accuracy.

*5: Since the calculation resolution is one micrometer
(0.001mm), using sub-micrometer resolution settings
may result in the 4th-place digit being unreliable,
particularly when B is set to a very low value
and C =0. It does not change at all with certain
combinations of calculation coefficient (for example,
A = 1, B = C =0). The 3rd-place digit representing
micrometers (if displayed) is always reliable.

Two of the wires inside the cable are separated for zero setting without touching the SET switch on the main body.
Use these cables in combination with commercially available switches. Zero setting is performed by briefly connecting these two wires together (less than a second), and ABS preset & recall by connecting for a second or more.
• Contact points for Mitutoyo’s dial indicators (Refer to pages F-51 to F-54 for details.)

Bifurcated connecting cable with zero-setting terminal

• 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.

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.

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.

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

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.

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

• Solar powered An environmentally friendly measuring instrument that does not require batteries, eliminating the hassle and cost of battery replacement. Can operate under minimum light conditions of 40 lux—lower than the level in a warehouse.
• Built-in recharger The large-capacity built-in reservoir capacitor allows you to use the indicator for long periods of time under light conditions below the minimum level.*
• User-friendly buttons All functions can be accessed by using the two or three large buttons on the front of the indicator.
• Origin recorded even if display disappears. The indicator includes an ABS (absolute) sensor that allows the previously set origin to be restored even if the display disappears due to insufficient light, making it easy to resume measurement.  This feature makes ID-SS ideal for long-time or multi-point measurement.

Dimensions

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.

Technical Data

Display: 6-digit LCD and sign
Scale type: ABSOLUTE electrostatic linear encoder
Measuring force: 1.5 N or less
Usable positions: All
Power supply: Solar battery (for indoor use)
Minimum Operating light: 40 lux
Note: A built-in reservoir capacitor allows a fully charged
ID-SS to be used for about 3.5 hours under light conditions below the minimum level.
The charging time differs depending on the environment, but it usually takes about 1.5 hours for a fully discharged
ID-SS to fully recharge under light conditions of 500 lux.
Maximum response speed: No limit (scan-type measurement is not supported)
Stem dia: 8mm (ISO/JIS type) or 3/8″(ANSI/AGD type)

The following is excerpted from JIS Z9110:2010 General rules of recommended lighting levels; 5.4 Factories:

Luminance (lux)	Location (permissible work)
1500	Very detailed visual work
750	Detailed visual work; design and drawing work
500	Regular visual work such as work carried out in a factory; monitoring work such as using instrument panels and control panels
300	Administrative work carried out in a warehouse
200	Control rooms, bathrooms, and places where manual light work is carried out
