DIY digital power standing waves meter, it is small and portable, built-in rechargeable battery does not require external power supplys, directly displays forward power, reflected power, antenna power, antenna efficiency, standing waves, battery voltage, accuracy meets amateur needs, high standing waves, the battery under voltage buzzer alarm function.
Features:
The standing waves meter adopts aluminum alloy housing, with high hardness, high conductivity, wear resistance and nice durability.
It is small and portable, built-in rechargeable battery does not require external power supplys.
Equipped with large OLED display, which can directly displays forward power, reflected power, antenna power, antenna efficiency, standing waves and battery voltage.
The accuracy meets amateur needs, high standing waves, with the battery under voltage buzzer alarm function.
With the buzzer on/off function, Chinese and English language switch function, and display mode switching function, 5 modes can be switched at will.
User guide:
In the power-on state, it shows red light when charging, green light when fully charged, and yellow light when under voltage.
When the VSWR is less than 1.5, the green indicator is on, the VSWR is greater than 1.5 and less than 2.5, the yellow indicator is on, and the VSWR is greater than 2.5. The red indicator is on.
If the standing waves is greater than 2.5 and less than 3, the buzzer will alarm intermittently, and if the standing waves is greater than 3, it will continuously alarm.
The battery is under-voltage, the buzzer keeps prompting, and the yellow indicator light is on.
