2. Setup
Before using your Starrett F2710-0 electronic indicator, follow these steps for initial setup:
- Mounting: Securely attach the indicator to a suitable stand or fixture using its 0.375" stem diameter or the mounting lug. Ensure the indicator is stable and free from vibrations.
- Power On: Press the power button to turn on the LCD display.
- Zero Setting: Position the indicator's contact point against your reference surface. Press the ZERO button to set the display to zero.
- Preset Mode (Optional): To set a specific reading at any point, move the indicator to the desired position and use the preset function. The display will show the set value, which is retained even if the indicator is powered off.
- Feature Lock (Optional): To prevent accidental changes to settings during operation, activate the Feature Lock function. Refer to the detailed instructions for enabling and disabling this feature.
3. Operating Instructions
The Starrett F2710-0 offers several functions to enhance measurement capabilities:
- Basic Measurement: After zeroing, move the indicator's contact point across the surface to be measured. The LCD will display the displacement from the zero point.
- T.I.R. (Total Indicator Reading): This function displays the difference between the highest and lowest values recorded during a measurement cycle. Activate T.I.R. mode before sweeping the surface.
- Tolerancing: Set high and low tolerance limits. If the measured value exceeds these limits, the display will flash, indicating an out-of-tolerance condition. Tolerance settings are retained even when the indicator is off.
- Hold Function: Press the HOLD button to freeze the current reading on the display. This is useful for recording measurements in difficult-to-view positions. The indicator also supports a minimum reading hold.
- Unit Conversion: If applicable, use the unit conversion button to switch between imperial (inches) and metric (millimeters) measurements.
4. Maintenance
Proper maintenance ensures the longevity and accuracy of your electronic indicator:
- Cleaning: Regularly clean the indicator's body and contact point with a soft, lint-free cloth. Avoid using harsh chemicals or abrasive materials.
- Storage: Store the indicator in its protective case when not in use. Keep it in a dry environment, away from extreme temperatures, dust, and direct sunlight.
- Battery Replacement: When the battery indicator appears on the LCD, replace the battery promptly to ensure continuous operation. Refer to the battery compartment for the correct battery type and replacement procedure.
- Calibration: For critical applications, periodic calibration by a qualified technician is recommended to maintain accuracy.
