4.2 Control Buttons

The 2x3 keypad includes navigation buttons (up, down, left, right), an Enter button, and a Power button for device operation.

4.3 Connectors

• RF Connector: UHF (SO-239) type, located at the top of the device, for connecting antennas or test loads.
• USB Port: Located at the bottom, used for charging the internal battery and connecting to a personal computer for data transfer or firmware updates.

5. Setup

5.1 Charging the Battery

1. Connect the supplied USB cable to the analyzer's USB port.
2. Connect the other end of the USB cable to a powered USB port on a computer or a USB wall adapter.
3. The device will indicate charging status on the display. A full charge typically takes several hours.

The analyzer can also draw power directly from the USB source when connected.

5.2 Initial Power On

1. Press and hold the Power button until the display activates.
2. The device will boot up and display the main menu or the last used measurement screen.

6. Operating Instructions

6.1 Basic Antenna Measurement

1. Ensure the analyzer is adequately charged or connected to a power source.
2. Connect the antenna to be tested to the UHF (SO-239) connector on the analyzer. Ensure the connection is secure.
3. Power on the device.
4. Navigate through the menu using the control buttons to select the desired measurement mode (e.g., SWR, Single Frequency).
5. Enter the desired frequency using the navigation buttons. The frequency can be adjusted with 1 KHz resolution.
6. The display will show the measured parameters, such as SWR, return loss, R, and X.

6.2 Display Modes

The RigExpert Stick 230 offers several display modes:

• Single Frequency: Displays SWR, return loss, R, X, Z, L, C, Magnitude, and Phase Angle at a specific frequency.
• SWR Chart: Plots SWR over a frequency range with 100 data points.
• HAM Bands Chart: Provides SWR charts specifically for IARU Region HAM bands.
• Multé Mode: Designed for quick checks of multiband antennas.

6.3 System Impedance Selection

The analyzer supports measurements for various system impedances. Access the settings menu to select the appropriate impedance (25, 50, 75, 100, 150, 200, 300, 450, or 600 Ohms) for your application.

6.4 PC Connection

Connect the analyzer to a personal computer via the USB port to:

• Transfer measurement data.
• Update device firmware.
• Utilize companion software (if available from RigExpert) for advanced analysis.

7. Maintenance

7.1 Cleaning

Wipe the device with a soft, dry cloth. Do not use liquid cleaners or solvents, as they may damage the display or casing.

7.2 Storage

Store the analyzer in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, ensure the battery is partially charged (around 50%) to prolong its lifespan.

7.3 Battery Care

The internal Li-Ion battery is designed for long life. To maximize battery health:

• Avoid fully discharging the battery frequently.
• Charge the battery regularly, even if the device is not in frequent use.
• Do not expose the device to temperatures above 60°C (140°F) or below -20°C (-4°F).

8. Troubleshooting

8.1 Device Does Not Power On

• Ensure the battery is charged. Connect the device to a USB power source and attempt to power it on.
• Verify that the Power button is pressed and held sufficiently.

8.2 Incorrect Measurement Readings

• Check all cable connections to ensure they are secure and free from damage.
• Verify that the correct system impedance is selected in the device settings.
• Ensure the antenna or load being tested is properly connected and functioning.

8.3 Display Issues

• If the display is unresponsive or shows artifacts, try restarting the device.
• Ensure the device is not exposed to extreme cold, which can temporarily affect e-paper display performance.
