Operating Instructions
Power On/Off
- To turn on: Press the "ON" button or slide the digital unit.
- To turn off: Press the "OFF" button. The unit also features automatic power off after a period of inactivity.
Zero Setting
To ensure accurate measurements, it is crucial to zero the gage before use:
- Place the base of the depth gage firmly on a flat, stable reference surface.
- Ensure the measuring rod is fully retracted and in contact with the reference surface.
- Press the "ZERO" button. The display should now read "0.000" or "0.00".
Inch/Millimeter Conversion
To switch between imperial (inches) and metric (millimeters) units, press the "in/mm" button. The display will instantly convert the reading to the selected unit.
Taking a Measurement
- Ensure the gage is properly zeroed on a suitable reference surface.
- Position the depth gage over the feature to be measured, ensuring the base is stable and flat on the reference plane.
- Extend the measuring rod into the depth feature until it makes firm contact with the bottom.
- Read the measurement directly from the digital display.
Data Output
The depth gage is equipped with a data output port. To utilize this feature, an optional data output cable (e.g., INSIZE models 7302-SPC5A or 7305-SPC2A) is required. Connect the cable to the port on the digital unit and to a compatible data collection system or computer for recording measurements.
Maintenance
Cleaning
Regularly clean the depth gage with a soft, dry cloth. For stubborn dirt, a cloth lightly dampened with isopropyl alcohol can be used. Avoid using harsh chemicals or abrasive materials that could damage the finish or electronic components.
Battery Replacement
When the display becomes dim or erratic, it is time to replace the CR2032 battery. Follow the battery installation steps outlined in the "Setup" section.
Storage
Store the depth gage in its original hard plastic blow mold case when not in use. Keep it in a clean, dry environment, away from direct sunlight, extreme temperatures, and high humidity. Ensure the measuring rod is fully retracted before storage to protect it from damage.
Troubleshooting
- Display is blank or dim:
Check the battery. Replace the CR2032 battery if it is low or depleted. Ensure the battery is inserted with the correct polarity.
- Inaccurate readings:
Ensure the gage is properly zeroed on a clean, flat reference surface. Clean the measuring surfaces of the gage to remove any debris. Verify that the workpiece surface is clean and free of burrs.
- Buttons are unresponsive:
Try replacing the battery. If the issue persists, contact INSIZE customer support.
