Key Components:

• Digital LCD Display: Shows measurement values, units (mm/inch), and an analog bar indicator.
• MODE Button (F1): Used to switch between various display modes or functions.
• ZERO/SET Button (F2): Sets the current position to zero or confirms settings.
• PRESET/ABS Button: Toggles between ABSOLUTE and incremental measurement modes, or sets a preset value.
• DATA Button (F3): Used for data output to external devices.
• ON/OFF Button: Powers the unit on or off.
• Measuring Spindle: The movable rod that contacts the workpiece for measurement.
• Stem: The cylindrical part used for mounting the indicator.

4. Setup

4.1 Battery Installation (If Required)

The indicator typically comes with a battery pre-installed. If battery replacement is necessary:

1. Carefully remove the battery cover, usually located on the back or side of the unit.
2. Insert a new SR44 (or equivalent) silver oxide button cell battery with the positive (+) side facing up.
3. Replace the battery cover securely.

4.2 Mounting the Indicator

Mount the indicator securely using its stem into a suitable stand or fixture. Ensure the mounting is rigid to prevent any movement during measurement, which could affect accuracy.

5. Operating Instructions

5.1 Power On/Off

• To power on, press the ON/OFF button.
• To power off, press and hold the ON/OFF button until the display turns off. The ABSOLUTE position is retained even when powered off.

5.2 Zero Setting

The ABSOLUTE system eliminates the need for repeated zero-setting. However, for incremental measurements:

1. Bring the measuring spindle into contact with the reference surface or workpiece.
2. Press the ZERO/SET button to set the display to zero at that position.

5.3 ABSOLUTE and Incremental Modes

Press the PRESET/ABS button to toggle between ABSOLUTE (ABS) and incremental (INC) measurement modes. In ABS mode, the origin is maintained even after power off. In INC mode, you can set a temporary zero at any point.

5.4 Unit Conversion (mm/inch)

Press the MODE button to cycle through available display options, which may include unit conversion between millimeters (mm) and inches (in), depending on the model configuration.

5.5 Tolerance Judgment

This indicator allows for Go/No-Go judgments by setting upper and lower tolerance limits. Refer to the detailed instructions in the full product manual for setting these limits using the MODE and ZERO/SET buttons. The analog bar indicator assists in visualizing the measurement relative to these limits.

5.6 Data Output

The indicator is equipped with a data output port. To transmit measurement data to an external device (e.g., computer, data processor), connect a compatible Mitutoyo data cable to the port and press the DATA button. Ensure the receiving device is properly configured to accept data.

6. Maintenance

6.1 Cleaning

Wipe the instrument with a soft, dry cloth. For stubborn dirt, a cloth lightly dampened with a neutral detergent may be used, followed by a dry wipe. Do not use organic solvents (e.g., thinner, benzene) as they may damage the finish or internal components.

6.2 Storage

Store the indicator in its original case or a protective container in a clean, dry environment, away from direct sunlight, extreme temperatures, and humidity. Ensure the measuring spindle is retracted or protected to prevent damage.

6.3 Battery Replacement

Replace the battery when the low battery indicator appears on the display or when the display becomes dim or unresponsive. Refer to section 4.1 for battery installation instructions. Dispose of used batteries according to local regulations.
