MULTIPLE FUNCTIONS: SWR meter has the function of delayed shutdown, automatic launch startup, battery undervoltage , LED dual indicator, power fine tuning, standing fine tuning, one click switch between Chinese and English menus, one click switch between multiple display interface, custom standing alarm setting, and custom shutdown delay setting
INTUITIVE DISPLAY: SWR power meter supports positive and negative power standing , with 1.3in color TFT display, direct reading of various parameters
ACCURATE AND PORTABLE: DIY digital power standing meter is small and portable, built in rechargeable battery, no need for external power supply, direct display of forward power, reflected power, antenna power, standing , battery voltage, accuracy to meet the needs of amateurs, possess high standing , battery undervoltage buzzer alarm function
SWITCHING MODE: The power range of standing meter is 0.5W‑120W, with a maximum of 200W. For long term tests below 120W, FM, AM, and CW modes are recommended. SSB modes are optional, one key display mode switch function, switch mode at will
INDICATOR AND ALARM: When power wattmeter is on, display red light when charging, green light when full, and yellow light when undervoltage. When VSWR is less than 1.5, the green indicator is on. When VSWR is greater than 1.5 and less than 2.5, the yellow indicator is on. When VSWR is greater than 2.5, the red indicator is on, if the standing is greater than 2.5 and less than 3, the buzzer will alarm intermittently, if the standing is greater than 3, (aisanray) will alarm
