Setup

The TGPKPGTCTA Digital Caliper comes ready for use. No assembly is required. Ensure the battery is properly installed before first use.

Battery Installation (if applicable):

While this model typically does not require user battery installation upon arrival, if the display does not turn on, you may need to check or replace the battery. Locate the battery compartment cover on the digital unit, slide it open, insert a new CR2032 3V lithium coin cell battery with the positive (+) side facing up, and close the cover securely.

Initial Preparation:

1. Clean the measuring surfaces with a soft, dry cloth to remove any dust or oil.
2. Press the ON/OFF button to power on the caliper.
3. Close the measuring jaws completely and press the ZERO button to set the display to zero. This ensures accurate measurements.

Operating Instructions

The digital caliper allows for four types of measurements: external, internal, depth, and step.

1. External Measurement:

1. Ensure the caliper is powered on and zeroed.
2. Open the external measuring jaws wider than the object to be measured.
3. Place the object between the external jaws.
4. Gently close the jaws until they make firm contact with the object. Use the thumb roller for fine adjustment.
5. Read the measurement directly from the digital display.
6. You can press the mm/inch button to switch units if needed.

2. Internal Measurement:

1. Ensure the caliper is powered on and zeroed.
2. Insert the internal measuring jaws into the opening to be measured.
3. Gently open the jaws until they make firm contact with the inner walls of the opening.
4. Read the measurement from the digital display.

3. Depth Measurement:

1. Ensure the caliper is powered on and zeroed.
2. Place the end of the main beam firmly on the top surface of the object or hole.
3. Extend the depth rod into the hole or recess until its end touches the bottom.
4. Read the measurement from the digital display.

4. Step Measurement:

1. Ensure the caliper is powered on and zeroed.
2. Place the step measuring face of the main beam on the higher surface.
3. Slide the movable jaw until its step measuring face rests on the lower surface.
4. Read the measurement from the digital display.

Using the ZERO Function:

The ZERO button allows you to set a relative zero point at any position. This is useful for differential measurements or for measuring deviations from a specific reference point.

Maintenance

Proper maintenance ensures 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 abrasive cleaners. Ensure no liquid enters the electronic components.
• Storage: Store the caliper in its original protective case in a dry, clean environment, away from direct sunlight, extreme temperatures, and humidity.
• Battery Replacement: If the display becomes dim or erratic, replace the battery (CR2032 3V lithium coin cell). Dispose of old batteries responsibly.
• Lubrication: Occasionally, a small amount of light machine oil can be applied to the sliding surfaces to ensure smooth movement. Wipe off any excess oil.
