1. Lifting Cap: Used to raise the plunger easily.
2. Bezel Clamp: Tightens to lock the bezel in place after zeroing.
3. Limit Pointer: Adjustable pointers to set tolerance limits for quick visual checks.
4. Revolution Counter: Displays the number of full rotations of the main pointer, indicating larger measurement increments.
5. Bezel: Rotated to set the gauge to zero.
6. Stem: The main body of the indicator, used for mounting.
7. Spindle: The movable rod that extends and retracts based on surface variations.
8. Contact Point: The tip that touches the surface being measured. Can be replaced with the included 22-piece set.

2.2 Magnetic Base and Arm Components

1. Fine-Tuning Knob: Allows for precise adjustments of the indicator position for accurate measurement.
2. Universal Rotating Design: Provides multi-angle adjustment for flexible positioning.
3. Clamp: Secures the adjustable arms in position.
4. V Base: Designed to allow secure attachment to round objects.
5. Magnetic Base: Provides a strong magnetic hold to metal surfaces for stable, hands-free operation.

3. Setup

Follow these steps to assemble and prepare your dial indicator for use.

1. Attach the Dial Indicator: Securely mount the dial indicator's stem into the clamp on the adjustable arm. Ensure it is tightened sufficiently to prevent movement during measurement.
2. Position the Adjustable Arm: Use the universal rotating design and clamp to position the dial indicator at the desired angle and height. The fine-tuning knob allows for precise adjustments.
3. Activate the Magnetic Base: Place the magnetic base on a clean, flat ferrous metal surface. Rotate the lever on the magnetic base to the 'ON' position to activate the strong magnetic hold. Ensure the base is firmly attached and stable before proceeding.

4. Operation

Accurate measurement requires careful execution of the following steps.

1. Position the Contact Point: Carefully lower the dial indicator so that its contact point gently touches the surface of the item to be measured. Ensure the contact point is perpendicular to the surface for the most accurate reading.
2. Zero the Gauge: Once the contact point is in position and the spindle is slightly compressed, rotate the outer bezel of the dial indicator until the main pointer aligns with the '0' mark. If applicable, use the bezel clamp to secure the bezel.
3. Take the Measurement: Slowly move the measured part or the dial indicator assembly while observing the main pointer and the revolution counter. The main pointer indicates fractions of an inch (0.001" increments), and the revolution counter tracks full inches.
4. Read the Measurement: The total measurement is the sum of the full revolutions shown on the revolution counter and the reading on the main dial.

5. Maintenance

Proper maintenance ensures the longevity and accuracy of your Spurtar Dial Indicator.

• Cleaning: After each use, wipe down the dial indicator and magnetic base with a clean, soft cloth. For stubborn grime, use a mild cleaning solution, ensuring no liquid enters the internal mechanisms of the dial indicator.
• Lubrication: Periodically apply a small amount of light machine oil to the spindle and other moving parts to ensure smooth operation. Avoid over-lubrication.
• Storage: Store the dial indicator and its accessories in the provided portable case when not in use. This protects it from dust, moisture, and physical damage. Store in a dry, temperature-controlled environment.
• Inspection: Regularly inspect the contact point for wear or damage. Replace if necessary using the included 22-piece contact point set.

6. Troubleshooting

If you encounter issues with your dial indicator, consider the following common problems and solutions:

• Inconsistent Readings:
  • Ensure the magnetic base is firmly attached to a stable, clean ferrous surface.
  • Verify the contact point is perpendicular to the measured surface.
  • Check for any play or looseness in the adjustable arm clamps. Tighten if necessary.
  • Clean the spindle and contact point for any debris that might impede movement.
• Pointer Not Moving Smoothly:
  • The spindle might be dirty or require lubrication. Clean and apply a small amount of light machine oil.
  • Check for any physical obstructions or damage to the spindle.
• Magnetic Base Not Holding Firmly:
  • Ensure the lever is fully in the 'ON' position.
  • Clean the bottom surface of the magnetic base and the mounting surface to remove any dirt or debris.
  • Confirm the mounting surface is made of a ferrous metal.
