Important Note on Screws:
Some users have reported that the included screws may be too short for certain VNA models or that screws were not included in their package. If you encounter this issue, replacement screws of size 2-56 machine thread are often suitable alternatives. Please ensure the screws are of appropriate length to secure the shell without damaging the internal components of your VNA.
5. Operating (with Shell)
Once your VNA-2.8in network analyzer is securely housed within the protective shell, you can operate it as usual. The shell is designed to provide physical protection during transport and use, without impeding access to the screen, buttons, or ports.
- The shell protects against minor impacts and scratches.
- All necessary ports (e.g., CH0, CH1) remain accessible for connecting cables.
- The screen area is open for full visibility and interaction.
6. Maintenance
To ensure the longevity and appearance of your protective shell, follow these simple maintenance guidelines:
- Cleaning: Wipe the shell with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the ABS material.
- Storage: Store the shell in a cool, dry place away from direct sunlight when not in use.
- Inspection: Periodically check the screws for tightness and the shell for any signs of damage.
7. Troubleshooting
This section addresses common issues you might encounter with the protective shell.
- Issue: Screws are missing or too short.
Solution: While the package is intended to include four screws, some users have reported them missing or being too short. If this occurs, you may need to source replacement screws. Common suitable replacements are 2-56 machine thread screws of appropriate length for your VNA model.
- Issue: VNA-2.8in does not fit correctly into the shell.
Solution: This shell is specifically designed for the VNA-2.8in network analyzer. Ensure your device is indeed a VNA-2.8in model. Variations in battery thickness or specific sub-models might cause fit issues. Verify that the VNA is correctly aligned with all internal guides and cutouts before attempting to close the shell. Do not force the shell closed if there is significant resistance.
