Setup
Before using your dial indicator, ensure it is properly set up:
- Unpacking: Carefully remove the dial indicator from its protective case.
- Mounting: Attach the dial indicator to a suitable stand or fixture using its lug back. Ensure the mounting is secure and stable to prevent movement during measurement.
- Contact Point: Verify that the contact point is clean and free from debris. The contact point is interchangeable, allowing for different applications.

Operating Instructions
Follow these steps for accurate measurement:
- Positioning: Position the dial indicator so that its contact point touches the surface to be measured. Ensure the spindle is perpendicular to the surface for optimal accuracy.
- Zeroing: Rotate the bezel to align the '0' mark with the main hand. This sets the reference point for your measurement.
- Measurement: Gently move the object or the indicator to measure variations. The main hand will indicate fractions of an inch (or millimeter), and the revolution counter hand will track full rotations.
- Reading: Read the measurement from the dial. Black graduations are for continuous readings, and red graduations are for balanced readings.

Maintenance
Proper maintenance ensures the longevity and accuracy of your dial indicator:
- Cleaning: After each use, wipe the instrument with a clean, soft cloth. For stubborn grime, use a cloth lightly dampened with a mild, non-corrosive cleaning solution.
- Lubrication: The internal mechanisms are factory-lubricated. Avoid applying additional lubricants unless specifically instructed by a qualified technician.
- Storage: Store the dial indicator in its original protective case in a dry, temperature-controlled environment to prevent corrosion and damage.
- Calibration: Regular calibration by a certified laboratory is recommended to maintain measurement accuracy, especially in professional or industrial settings.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate readings | Dirty contact point or spindle; loose mounting; instrument damage; out of calibration. | Clean contact point and spindle; secure mounting; inspect for damage; recalibrate. |
| Sticking spindle | Accumulation of dirt or debris; lack of lubrication. | Clean the spindle thoroughly; if problem persists, consult a technician. |
| Bezel does not rotate smoothly | Dirt or debris under the bezel. | Gently clean around the bezel. Do not force rotation. |
