Feature: 1. Accurate Measurement: This power meter offers accurate measurements with a ranges of 0.5W to 120W (up to 200W in certain modes). For prolonged FM, AM, and CW modes, it is recommended to stay below 120W, while SSB mode allows for higher power options. 2. OLED Display: Featuring a 128*64 OLED screen, the SWR meter directly displays forward power, reflected power, antenna power, SWR, battery voltage, and other parameters. The display supports language switching between English and Chinese. 3. High SWR Alarm Function: The power meter supports a high SWR alarm function. When the SWR is below 1.5, a green indicator light will illuminate. When the SWR is between 1.5 and 2.5, a yellow indicator light will illuminate. If the SWR exceeds 2.5, a red indicator light will illuminate. The alarm threshold can be customized. 4. Convenient Indicator Lights: The power meter is equipped with indicator lights for various statuses. During charging, a red light will be displayed. When fully charged, a green light will be displayed. In the event of low battery voltage, a yellow light will illuminate, and the continuous beeping sound can be easily turned off with a button press. 5. Reliable Quality \u0026 Built-in Battery: Crafted with high-quality aluminum alloy, it is lightweight, compact, and has nice durability. It features a built-in 1000mAh large-capacity battery, providing long battery time. The auto power-off function can be set, and the delay time is customizable. 6. Designed for Amateur Enthusiasts: This digital power meter is specifically designed for amateur radio enthusiasts. It is suitable for anyone interested in measuring and optimizing antenna performance. Whether you are a beginner or an experienced user, this meter provides the necessary tools for enhancing your radio experience.
