4.2 Initial Power On and Zero Setting
- Press the ZERO/ON/OFF button to turn on the device.
- Ensure the measuring base is clean and free of debris.
- Place the depth gauge on a flat, stable reference surface, ensuring the measuring rod is fully retracted and the base is flush with the surface.
- Press the ZERO/ON/OFF button again to set the display to zero. This establishes your reference point.
5. Operating Instructions
5.1 Basic Measurement
- Turn on the depth gauge by pressing the ZERO/ON/OFF button.
- Select the desired unit (mm or inch) by pressing the mm/inch/SET button.
- Place the base of the gauge firmly on the reference surface of the object to be measured.
- Extend the measuring rod into the groove or hole until it reaches the bottom.
- Read the depth measurement directly from the digital display.
- To take an incremental measurement, set the zero point at any desired position by pressing the ZERO/ON/OFF button.
5.2 Wireless Data Transmission (Model 5114L-50 only)
The 5114L-50 model features built-in wireless data output. To utilize this function, ensure your receiving device (e.g., computer with compatible software) is properly configured to receive data from the gauge. Consult your receiving device's manual for specific pairing and data acquisition instructions. The gauge will transmit measurement data wirelessly when activated.
5.3 Upper and Lower Limit Setting (Model 5114L-50 only)
The 5114L-50 allows you to set upper and lower measurement limits for quality control or specific application requirements. Refer to the detailed instructions below:
- Press and hold the mm/inch/SET button to enter the limit setting mode.
- Use the ZERO/ON/OFF and mm/inch/SET buttons to adjust the upper limit value.
- Press the OK button to confirm the upper limit and proceed to set the lower limit.
- Adjust the lower limit value using the ZERO/ON/OFF and mm/inch/SET buttons.
- Press the OK button to confirm the lower limit and exit the setting mode.
- During measurement, the gauge may indicate if the reading falls outside the set limits (e.g., with a flashing display or specific icon).
6. Maintenance
- Cleaning: Regularly wipe the measuring surfaces and body with a clean, dry, lint-free cloth. Avoid using solvents or abrasive cleaners.
- Storage: Store the depth gauge in its protective plastic box in a dry, clean environment, away from direct sunlight, extreme temperatures, and high humidity.
- Battery Replacement: When the display becomes dim or erratic, replace the CR2032 battery promptly. Follow the battery installation steps in Section 4.1.
- Avoid Impact: Handle the gauge with care to prevent dropping or impact, which can affect its accuracy.
- Environmental Conditions: Operate and store the device within the specified working environment temperature (0-40°C) and relative humidity (80%).
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or dim | Low battery or incorrect battery installation. | Replace the CR2032 battery, ensuring correct polarity. |
| Inaccurate readings | Dirty measuring surfaces, improper zero setting, or physical damage. | Clean measuring surfaces. Re-zero the gauge on a flat surface. Check for physical damage. |
| Buttons unresponsive | Low battery or internal malfunction. | Replace battery. If problem persists, contact support. |
| Wireless transmission not working | Receiving device not paired or out of range, or internal issue. | Ensure receiving device is correctly set up and within range. Check gauge battery. |
8. User Tips
- Always ensure the measuring surfaces are clean before taking a measurement to avoid inaccuracies.
- For consistent results, always zero the gauge on the same reference surface or a known flat surface before starting a new set of measurements.
- When measuring tire tread depth, ensure the gauge is perpendicular to the tire surface for the most accurate reading.
- Take advantage of the upper and lower limit setting function (on Model 5114L-50) for quick visual checks in repetitive tasks.
- If using the wireless transmission feature, keep the receiving device close to the depth gauge to maintain a stable connection.
