Mitutoyo 500-706-20 Digital Caliper Instruction Manual

Introduction

Precision is at the core of measuring instruments and solutions, and the Mitutoyo name has come to embody reliable precision in all applications. This manual provides essential information for the proper use and care of your Mitutoyo 500-706-20 Digital Caliper.

Key features of this digital caliper include:

• Reliable measurements across various applications.
• Measurement deviation limit (E MPE): ±0.02 mm.
• Measurement error limit (S MPE): ±0.04 mm.
• Automatic shut-off after 20 minutes of inactivity to conserve battery life.

Setup

1. Unpacking and Inspection

Carefully remove the caliper from its packaging. Inspect the device for any visible damage or missing components. Ensure all included accessories, such as the protective box and battery, are present.

2. Battery Installation

The Mitutoyo 500-706-20 Digital Caliper requires one LR44 battery (included). Locate the battery compartment cover, typically on the back of the digital display unit. Slide or unclip the cover, insert the LR44 battery with the correct polarity (+ side up), and then securely close the compartment.

3. Initial Power-On and Cleaning

Press the ON/OFF button to power on the caliper. The display should illuminate and show '0.00'. Before first use, gently wipe the measuring surfaces and the main beam with a clean, lint-free cloth to remove any dust or protective oils.

Operating Instructions

1. Power On/Off

Press the ON/OFF button to turn the caliper on or off. The caliper will automatically shut off after 20 minutes of inactivity.

2. Zero Setting

Before taking any measurement, ensure accuracy by setting the zero point. Close the external measuring jaws completely and press the ZERO button. The display should read '0.00'. This establishes a reference point for subsequent measurements.

3. External Measurement

Place the object to be measured between the external jaws. Slide the movable jaw until it makes firm, but not excessive, contact with the object. Read the measurement directly from the digital display.

4. Internal Measurement

Use the smaller, upper jaws for internal dimensions. Insert the jaws into the opening of the object and expand them until they contact the inner surfaces. Read the measurement from the display.

5. Depth Measurement

Extend the depth rod from the end of the caliper into the depth of the feature you are measuring. Ensure the end of the main beam rests firmly on the top surface of the object. Read the measurement.

6. Step Measurement

Utilize the step measuring face located at the end of the main beam. Place the fixed jaw on the higher surface and extend the movable jaw to the lower surface to measure the step height. Read the measurement.

Maintenance

1. Cleaning

Regularly clean the measuring surfaces and the main beam with a dry, lint-free cloth. Avoid using solvents, abrasive cleaners, or any liquids that could damage the electronic components or measuring surfaces. Keep the digital display clean and dry.

2. Battery Replacement

When the display indicates a low battery (e.g., a flashing battery icon) or becomes dim, it is time to replace the LR44 battery. Follow the battery installation steps outlined in the Setup section, ensuring correct polarity.

3. Storage

Store the caliper in its original protective case when not in use. Keep it in a dry, clean environment, away from direct sunlight, extreme temperatures, and high humidity. Ensure the measuring jaws are slightly open (approximately 0.5-1 mm) to prevent stress on the measuring surfaces and to avoid potential corrosion if moisture is present.

Troubleshooting

1. Display Not Working or Dim

• Check if the battery is correctly installed with the proper polarity.
• Replace the LR44 battery with a new one.
• Ensure the battery compartment cover is securely closed.

2. Inaccurate or Inconsistent Readings

• Ensure the measuring surfaces are clean and free from dust, debris, or oil.
• Always zero the caliper before each measurement by closing the jaws and pressing the ZERO button.
• Avoid applying excessive force when taking measurements, as this can lead to deflection and inaccurate results.
• Ensure the object being measured is stable and properly positioned between the jaws.

3. Jaws Not Moving Smoothly

• Clean the main beam and ensure no debris is obstructing the movement of the movable jaw.
• Do not lubricate the beam, as this can attract dust and impair accuracy.
