4.2. Installing Linear Scales
The linear scales (optical rulers) are the core of the measurement system. Install them parallel to the machine's axes of motion.
- Identify the appropriate travel length for each axis (X, Y, Z if applicable).
- Attach the linear scale body to the stationary part of the machine using the provided mounting brackets and screws.
- Attach the readhead to the moving part of the machine, ensuring it slides smoothly along the scale body without binding.
- Ensure proper alignment to prevent measurement errors and damage to the scale.
- Install the scale covers to protect the linear scales from dust, oil, water, and iron filings.
Linear Scale Components:
- Readhead: High precision readhead with high strength magnesium-aluminum alloy and NSK bearings.
- Adhesive Strips: Water- and oil-resistant, dust-proof adhesive strip made of special PU, corrosion-resistant and low resistance.
- Raster Glass: Super white ultra-thin float glass, 20µm pitch.
- Profile: Industrial grade aluminum alloy profile, anodized treatment, ruler body correction, anti-vibration and anti-pressure without deformation.
- Cable: 304 stainless steel conduit, corrosion and oil resistance, strong oxidation resistance. Default length 3 meters, can be customized.
- Protective Housing: Sealed protective cover against dust, oil, water, and iron filings.
4.3. Wiring and Power Connection
- Connect the linear scales to the corresponding axis inputs (X, Y) on the back of the DRO display unit. Ensure the connectors are firmly seated.
- Connect the power cable to the DRO unit and then to a suitable AC power outlet (100V-240V, 50Hz-60Hz).
- Turn on the power switch on the back of the DRO unit.
The DRO unit supports various plug options for different countries:

- Environmental Protection: Keep the DRO unit and scales away from excessive dust, moisture, and direct sunlight. The protective covers for the linear scales should always be in place during operation to prevent contamination.
- Cable Inspection: Periodically check all cables for any signs of wear, cuts, or damage. Replace damaged cables immediately to prevent electrical issues or signal loss.
- Calibration: While the system has linear error compensation, periodic checks against known standards can help maintain optimal accuracy.
7. Troubleshooting
If you encounter issues with your DRO system, consider the following common problems and solutions:
- No Display/Power:
- Check if the power cable is securely connected to both the DRO unit and the power outlet.
- Ensure the power switch on the back of the unit is in the 'ON' position.
- Verify the power outlet is functional. - Inaccurate Readings:
- Check the linear scales for any debris, oil, or damage that might obstruct the readhead.
- Ensure the scales are properly aligned and securely mounted.
- Verify that the correct resolution and direction settings are configured in the DRO unit (refer to Section 5.3).
- Check for loose cable connections between the scales and the DRO unit. - Intermittent Readings:
- Inspect scale cables for damage or loose connections.
- Ensure the readhead moves freely along the scale without any obstructions or excessive friction. - Buttons Unresponsive:
- Power cycle the DRO unit (turn off, wait a few seconds, then turn on).
- Ensure the keypad is clean and free from sticky residues.
For persistent issues not resolved by these steps, please contact customer support.
8. User Tips
- Confirm Scale Length: When ordering a complete kit, always double-check and clearly communicate the required travel length of your linear scales to the seller. This ensures you receive the correct components for your specific machine.
- Initial Setup: Take your time during the initial installation and alignment of the linear scales. Precise alignment will prevent future accuracy issues and extend the life of the scales.
- Parameter Settings: Explore the internal functions (accessed by holding '8') to customize settings like resolution, direction, and diameter/radius conversion to best suit your machining tasks.
