5. Operating Instructions: Power Measurement

Follow these steps to measure the RF power output of your radio device:

1. Ensure the meter is adequately charged.
2. Connect your radio device to the bottom connector of the SW-33 Mark II. Use appropriate adapters if necessary (included in the package).
3. Connect a suitable dummy load to the top connector of the SW-33 Mark II. Ensure the dummy load can handle the maximum power output of your radio.
4. Power on the SW-33 Mark II. Press the power button until the indicator light is at the top left, displaying FW (Forward Power) values.
5. Hold down the Push-To-Talk (PTT) button on your radio for a few seconds.
6. Observe the FW value on the meter's display. This indicates the forward power output of your radio.

6. Operating Instructions: SWR Measurement

Follow these steps to measure the SWR of your antenna:

1. Ensure the meter is adequately charged.
2. Connect your radio device to the bottom connector of the SW-33 Mark II. Use appropriate adapters if necessary.
3. Connect the antenna you wish to test to the top connector of the SW-33 Mark II. Ensure the antenna is positioned vertically and there are no obstructions nearby.
4. Power on the SW-33 Mark II. Press the power button until the indicator light is at the middle left, displaying SWR values.
5. It is recommended to test with your radio device set to high power for more accurate results.
6. Hold the meter steadily and hold down the Push-To-Talk (PTT) button on your radio for a few seconds.
7. Observe the SWR value on the meter's display. An SWR value closer to 1.0 indicates better antenna performance and a good match.
