• Socket A (Data Output Interface): Enables data transfer to a computer.
• Socket B (Battery Capsule): Facilitates easy battery replacement.

4. Setup

Before taking measurements, the digital dial gauge needs to be properly set up, often with a magnetic base for stability.

4.1 Attaching the Back Cover

The included back cover allows for versatile mounting options. It can be attached to the rear of the dial gauge and then secured to a magnetic base or other fixture.

4.2 Using a Magnetic Base (Optional)

For stable and precise measurements, it is recommended to use the dial gauge with a magnetic base. The magnetic base allows for flexible positioning and secure attachment to ferrous surfaces.

Video 1: Demonstration of a magnetic base being activated and deactivated. This shows how the base securely attaches to a metal surface and can be easily released.

To attach the dial gauge to a magnetic base:

1. Ensure the magnetic base is clean and free of debris.
2. Attach the dial gauge to the magnetic base's arm using the appropriate clamp.
3. Position the magnetic base on a stable ferrous surface.
4. Turn the knob on the magnetic base to the "ON" position to activate the magnet, securing the base in place.
5. Adjust the arm of the magnetic base to position the dial gauge's probe over the measurement point. Tighten all adjustment knobs to secure the gauge's position.

5. Operating Instructions

Follow these steps to take accurate measurements with your digital dial gauge.

5.1 Basic Measurement

1. Power On: Press the ON/OFF button to turn on the gauge.
2. Select Units: Press the inch/mm button to switch between millimeters (mm) and inches (in) as needed.
3. Zeroing:
   • Position the contact probe against the reference surface or the lowest point of the object to be measured.
   • Press the ZERO button. The display will show "0.00" (or "0.000" in inches), establishing this point as your zero reference.
4. Take Measurement: Move the probe to the point you wish to measure. The display will show the deviation from your zero reference.
5. Power Off: Press the ON/OFF button again to turn off the gauge when not in use.

6. Maintenance

Proper maintenance ensures the longevity and accuracy of your digital dial gauge.

• Cleaning: Wipe the gauge with a soft, dry cloth after each use. Do not use solvents or abrasive cleaners.
• Storage: Store the gauge in its protective case in a dry, clean environment away from direct sunlight and extreme temperatures.
• Battery Replacement: The gauge uses an LR44 battery. If the display becomes dim or erratic, replace the battery by opening Socket B (Battery Capsule) as shown in Figure 3. Ensure correct polarity.
• Probe Replacement: The M2.5 contact probe is interchangeable. If the probe becomes worn or damaged, it can be unscrewed and replaced with a new one.
