Fangrui Product Details Rc Parts Accs:motor Components For Vehicle Type:airplanes Type: Airplanes Material: Metal Tool Supplies:battery Use:vehicles Remote Control Toys Remote Control Peripherals/devices: Rc Tester Voltage Detection Function: It Is Very Convenient To Calculate The Voltage, Current, Power, Discharge Capacity And Discharge Time Of The Aircraft, And It Is Convenient To Calculate The Force Effect Of The Multi- Aircraft. The Unit Of Force Effect Is G/w (/watt), And The Calculation Method Is: The Take-off Weight Is Divided By The Current Display, And The Effect Is 2800g. After Taking Off, The Hovering State Is Viewed As 230w, So The Force Effect Of This Aircraft Is 2800g/ 230w=1.21g/w. High Precision It Is More Suitable For The Measurement Of Small Current, Such As: Solar Energy, Electric Vehicle Measurement, Etc. Welcome To Consult And Order. Due To Cost Reasons, The Zero Point Of Some Power Meters May Not Return To Zero During Use. It Is Recommended That The User Reconnect The Power To Reset The Count Of The Pow
