4.2 Preheating for Accuracy

To ensure the accuracy of measurements and calibration, it is recommended to preheat the instrument for at least 15 minutes before performing critical tests.

4.3 Connecting an Antenna or Load

Carefully connect the antenna or test load to the RF connector on the top of the analyzer. Ensure the connection is secure to avoid inaccurate readings.

5. Operating Instructions

5.1 Power On/Off

• Power On: Press the Power button (usually located on the right side).
• Power Off: From the boot state, long-press (for 2 seconds or more) the Power button, then release. The instrument will shut down.
• Forced Shutdown: In a shutdown state, hold down the CTRL key and then press the Power button to initiate a forced shutdown.

5.2 Basic Measurement Mode

Upon powering on, the device typically defaults to a measurement display showing various parameters. Use the arrow keys to navigate or adjust frequency.

5.4 Adjusting Frequency

Use the Left and Right arrow buttons to adjust the operating frequency. The frequency step is 1kHz, allowing for fine-tuning.

5.5 Menu Navigation

Press the 'M' button to access the main menu. Use the arrow keys to scroll through options and 'OK' to select. Refer to the on-screen prompts for specific menu functions such as calibration, sweep settings, or saving data.

6. Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents.
• Storage: Store the analyzer in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery Care: For long-term storage, ensure the battery is partially charged (around 50%) to prolong its lifespan. Recharge periodically if stored for extended periods.

7. Troubleshooting

• Device not powering on: Ensure the battery is charged. If not, connect to a charger. If still unresponsive, try the forced shutdown/restart procedure (hold CTRL + Power).
• Inaccurate readings: Ensure the device has preheated for at least 15 minutes. Check all cable connections for tightness. Perform a calibration if available in the menu.
• Display frozen: Try restarting the device using the power off procedure. If unresponsive, use the Reset button (if accessible, often a small pinhole).
• Battery not charging: Verify the charging cable and adapter are working correctly. Try a different USB power source.
