5.3 Calibration
For accurate measurements, especially after changing test setups or operating conditions, calibration is recommended.
- Access the "Calibration" interface by pressing the M button (1) after entering the "System Information" interface (which is accessed by pressing CTRL then M).
- Follow the on-screen prompts to perform calibration.
5.4 Auto Power Off Setting
To adjust the auto power off time:
- Navigate to the settings menu (usually accessible via the M button or a combination with CTRL).
- Select the "Auto Power Off" option.
- Choose your desired setting: "Always On" or a time duration from 5 minutes to 60 minutes.
6. Care and Maintenance
- Cleaning: Use a soft, dry cloth to clean the device. Do not use harsh chemicals or abrasive materials.
- Storage: Store the analyzer in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Charge it regularly, even if not in use for extended periods.
- Connector Care: Keep the SMA-K connector clean and free from dust or debris to ensure good contact and accurate measurements.
7. Troubleshooting
- Device not powering on: Ensure the battery is charged. If not, connect it to a charger. If the issue persists, try pressing the RESET hole (10) with a thin object.
- Inaccurate readings: Perform a calibration. Check that the connectors are clean and securely attached. Ensure the test environment is free from strong electromagnetic interference.
- Device freezes/becomes unresponsive: Use a thin object to press the RESET hole (10) to restart the device.
- Charging issues: Ensure you are using a charger with an output current of at least 1A. Check the Mini-USB cable for damage.
