• Ensure the battery is sufficiently charged. Connect the device to a power source and allow it to charge for at least 30 minutes before attempting to power on again.
• Check the power switch/button for proper engagement.
• Inaccurate Measurements:
• Perform a full calibration (OPEN, SHORT, LOAD) before each measurement session or when changing frequency ranges significantly.
• Ensure all RF cables and connectors are securely attached and in good condition.
• Verify that the correct measurement parameters (start/stop frequency, sweep points) are set for your application.
• Screen Unresponsive/Frozen:
• Try a soft reset by holding down the power button for several seconds until the device restarts.
• Ensure the stylus or your finger is making proper contact with the screen.
• Data Saving Issues:
• Check if the MicroSD card is correctly inserted and not full.
• Ensure the MicroSD card is formatted correctly (FAT32 is usually recommended).
• Connectivity Problems with PC/Android:
