Key features include:
- Digital display for measurements up to 0.01mm.
- Absolute (ABS) measurement system for stable readings.
- Data output terminal for integration with statistical process control or measurement systems.
- Capability for span attachment.
Setup
- Unpacking: Carefully remove the depth gauge from its packaging. Inspect for any visible damage.
- Battery Installation: The gauge comes with one SR44 silver oxide button battery (No. 938882) for monitoring purposes. To install or replace the battery:
- Locate the battery compartment cover, usually on the back or side of the display unit.
- Use a small screwdriver to open the cover.
- Insert the SR44 battery with the positive (+) side facing up.
- Securely close the battery compartment cover.
- Initial Power On: Press the ON/OFF button to power on the gauge. The digital display should illuminate.
- Zero Setting: Place the gauge on a flat, stable reference surface. Ensure the measuring rod is fully retracted and the base is flush with the surface. Press the ZERO button to set the display to zero.
Operation
Follow these steps for accurate depth measurement:
- Preparation: Ensure the measurement surface and the gauge's base are clean and free of debris.
- Positioning: Place the gauge's base firmly on the reference surface of the workpiece.
- Measurement: Slowly extend the measuring rod into the depth to be measured until it makes firm contact with the bottom.
- Reading: Read the measurement directly from the digital display. The gauge provides readings up to 0.01mm.
- Data Output (Optional): If using a statistical process control or measurement system, connect the data output terminal to the appropriate interface and transfer the measurement data as needed.
- Power Off: Press the ON/OFF button to turn off the gauge when not in use to conserve battery life.
Maintenance
Proper maintenance ensures the longevity and accuracy of your depth gauge:
- Cleaning: After each use, wipe the measuring surfaces and the body of the gauge with a clean, dry, soft cloth. Do not use solvents or abrasive materials.
- Storage: Store the gauge in its protective case in a dry, temperature-stable environment, away from direct sunlight and dust.
- Battery Replacement: Replace the SR44 battery approximately every 3 years, or when the low battery indicator appears on the display.
- Calibration: Regular calibration by a qualified technician is recommended to maintain measurement accuracy, especially for critical applications.
Troubleshooting
Refer to the following table for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Display does not turn on. | Dead battery or incorrect battery installation. | Replace the SR44 battery or ensure it is installed correctly with the positive (+) side up. |
| Inaccurate readings. | Dirty measuring surfaces, improper zero setting, or environmental factors. | Clean measuring surfaces. Re-zero the gauge on a flat reference surface. Ensure stable operating conditions. Consider professional calibration if issues persist. |
| Display shows error message. | Internal malfunction or extreme operating conditions. | Turn the gauge off and then on again. If the error persists, contact Mitutoyo customer support. |
