Mitutoyo 543-490B Absolute LCD Digimatic Indicator ID-C Instruction Manual

Introduction

This manual provides essential instructions for the safe and effective use of the Mitutoyo 543-490B Absolute LCD Digimatic Indicator ID-C. Please read this manual thoroughly before operating the instrument and keep it for future reference. This indicator is designed for precise dimensional measurement, offering high accuracy and ease of use with its digital display and advanced functions.

Product Features

• Compact design, similar to standard Series 2 dial indicators.
• Large, easy-to-read LCD display.
• Stem diameter: 8mm, Thread: M2.5 x 0.45.
• Go/+/-NG judgment function with settable upper and lower tolerance limits, displaying results in full-size characters.
• Toggleable positive/negative count for spindle movement.
• Alarm functions for low voltage, counting value composition error, over-flow error, and tolerance limit setting error.
• Internal calculations using the simple formula F(x) = Ax.
• Absolute linear encoder ensures the indicator always displays the spindle's absolute position from the origin upon power-on.
• Unlimited response speed eliminates over-speed errors.
• Indicator face can be rotated 330 degrees for optimal viewing angle.
• Equipped with SPC data output capability.

Safety Information

To ensure safe operation and prevent damage to the instrument or injury to the user, please observe the following precautions:

• Do not disassemble or modify the indicator. This may lead to malfunction or damage.
• Avoid dropping or subjecting the indicator to strong impacts.
• Keep the indicator away from direct sunlight, high temperatures, high humidity, and dusty environments.
• Do not use the indicator in environments with excessive vibration or strong magnetic fields.
• Handle the measuring probe carefully to avoid bending or damaging it.
• Ensure the power source (if applicable) meets the specified requirements.
• When cleaning, use a soft, dry cloth. Avoid using organic solvents.

Components Overview

The Mitutoyo 543-490B Digimatic Indicator consists of several key components:

• Display Unit: Features a large LCD for clear reading of measurements and settings.
• Stem: The main body of the indicator, typically mounted to a stand or fixture.
• Spindle/Measuring Probe: The movable part that contacts the workpiece to take measurements.
• Buttons: For various functions such as ON/OFF, ZERO, ABS/INC, and tolerance setting.
• Data Output Port: For connecting to external devices for SPC data collection.

Setup

1. Battery Installation

The indicator typically comes with a battery installed. If replacement is needed, refer to the battery compartment cover for instructions on opening and replacing the battery. Ensure correct polarity.

2. Mounting the Indicator

1. Securely mount the indicator's stem (8mm diameter) into a suitable measuring stand or fixture. Ensure the mounting is firm to prevent movement during measurement.
2. Position the indicator so that the measuring probe is aligned with the workpiece to be measured.
3. Adjust the indicator's face by rotating it up to 330 degrees for optimal viewing angle.

3. Initial Power On

Press the ON/OFF button to power on the indicator. The display will show the absolute position from the origin due to the absolute linear encoder.

Operating Instructions

1. Basic Measurement

1. Ensure the indicator is properly mounted and powered on.
2. Bring the measuring probe into contact with the workpiece. The display will show the measured value.
3. For incremental measurements, press the ZERO button at the desired reference point. The display will reset to zero, and subsequent movements will be relative to this point.
4. To return to absolute measurement, press the ABS/INC button. The indicator will display the absolute position from its origin.

2. Go/+/-NG Judgment

1. Enter the tolerance setting mode (refer to the specific button on your model, often labeled TOL or similar).
2. Set the upper and lower tolerance limits according to your measurement requirements.
3. During measurement, the indicator will display "GO" if the value is within tolerance, or "+NG" / "-NG" if it exceeds the upper or lower limit, respectively.

3. Data Output (SPC)

Connect the indicator to a compatible data processor or computer using the SPC data output port. Refer to the data processor's manual for specific connection and software instructions.

4. Spindle Movement Count Direction

The positive/negative count direction resulting from the spindle's up/down movement can be toggled. Consult the indicator's specific button layout for this function, often labeled DIR or similar.

Maintenance

1. Cleaning

• Wipe the indicator body and spindle with a soft, clean, dry cloth.
• For stubborn dirt, a cloth lightly dampened with neutral detergent may be used, followed by a dry cloth.
• Do not use organic solvents such as thinner or benzene, as they may damage the display or casing.
• Keep the measuring probe clean and free from debris to ensure accurate readings.

2. Storage

• Store the indicator in its protective case when not in use.
• Avoid storing in areas with direct sunlight, high temperatures, high humidity, or excessive dust.
• Ensure the measuring probe is retracted or protected to prevent damage.

3. Battery Replacement

When the low voltage alarm appears on the display, replace the battery promptly to ensure continued operation and prevent data loss. Refer to the battery compartment for specific battery type and replacement instructions.
