5. Operating Instructions: Power Measurement
Follow these steps to measure the RF power output of your radio device:
- Ensure the meter is adequately charged.
- Connect your radio device to the bottom connector of the SW-33 Mark II. Use appropriate adapters if necessary (included in the package).
- 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.
- 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.
- Hold down the Push-To-Talk (PTT) button on your radio for a few seconds.
- 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:
- Ensure the meter is adequately charged.
- Connect your radio device to the bottom connector of the SW-33 Mark II. Use appropriate adapters if necessary.
- 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.
- Power on the SW-33 Mark II. Press the power button until the indicator light is at the middle left, displaying SWR values.
- It is recommended to test with your radio device set to high power for more accurate results.
- Hold the meter steadily and hold down the Push-To-Talk (PTT) button on your radio for a few seconds.
- Observe the SWR value on the meter's display. An SWR value closer to 1.0 indicates better antenna performance and a good match.
