4.2 Measuring Techniques

Ensure the caliper jaws are clean before taking measurements. Move the sliding jaw to open the caliper, position the object, and then gently close the jaws until they make contact.

4.2.1 Outside Measurement

Use the large outside jaws to measure external dimensions of objects.

1. Open the outside jaws wider than the object.
2. Place the object between the outside jaws.
3. Gently close the jaws until they firmly contact the object.
4. Read the measurement on the LCD display.

4.2.2 Inside Measurement

Use the small inside jaws to measure internal dimensions, such as the diameter of a hole or the width of a groove.

1. Insert the inside jaws into the opening to be measured.
2. Open the jaws until they firmly contact the inner surfaces.
3. Read the measurement on the LCD display.

4.2.3 Depth Measurement

Use the depth bar to measure the depth of holes, slots, or steps.

1. Place the end of the main scale firmly on the top surface of the object.
2. Extend the depth bar into the hole or slot until its end touches the bottom.
3. Read the measurement on the LCD display.

5. Care and Maintenance

Proper care will ensure the longevity and accuracy of your digital caliper:

• Cleaning: Wipe the caliper clean with a dry, soft cloth after each use. Avoid using solvents or harsh chemicals, as they may damage the nylon frame or electronic components.
• Storage: Store the caliper in a clean, dry place, away from direct sunlight, extreme temperatures, and high humidity. Keep the jaws closed when not in use to protect them.
• Battery Replacement: Replace the LR44 battery when the display becomes dim or erratic. Always dispose of used batteries responsibly.
• Avoid Impact: Do not drop the caliper or subject it to strong impacts, as this can affect its accuracy and functionality.

6. Troubleshooting

If you encounter issues with your digital caliper, refer to the following common problems and solutions:

• Display is blank or dim:
  Solution: The battery may be low or depleted. Replace the 1.5V LR44 button cell battery. Ensure the battery is inserted with the correct polarity.
• Readings are inconsistent or inaccurate:
  Solution: Clean the measuring surfaces and the main beam thoroughly. Ensure there is no dust or debris obstructing the sliding mechanism. Press the ZERO button with the jaws closed to re-zero the caliper.
• Sliding jaw is stiff or difficult to move:
  Solution: Clean the main beam and the sliding mechanism. A small amount of silicone-based lubricant can be applied to the beam, but avoid getting it on the electronic components.
• Caliper does not turn on:
  Solution: Check battery installation and ensure it is a fresh battery. If the issue persists, contact customer support.
