SKYRC motor analyzer is a precision electronic device that is especially designed for measuring the KV value, RMP, current drawn, motor timing, vibration noise level and checking the function of hall effect sensors of a brushless motor. It comes with a LCD diaplay screen which can display real time measuring value of either sensored or sensorless brushless motor. Features: KV measurement RPM measurement Voltage measurement Ampere measurement Motor timing checking: Average timing, phase A, B, C timing Noise level Hall effect sensor test Specifications: Input voltage: 7.4-8.4V (suggested to use 7.4V 2S LiPo battery) LCD display screen: Blue backlight background, white text, 16 characters X 2 lines Supported motor: Sensored or sensorless brushless motor(2 Poles to 36 Poles) Current drawn less than 30A at 8.4V without loading KV value accuracy: +/- 3% Motor timing accuracy: +/- 4% Noise level measurement range: 60dB-120dB Dimension: 136.5 * 80.6 * 24.5mm Net weight: 282g (without cable) Package Information: Package size: 17 * 12.5 * 5.5cm / 6.7 * 5 * 2.2in Package weight: 453g / 1lb Brand gift box package Package List: 1 * SKYRC Brushless Motor Analyzer 1 * Motor Sensor Cable 1 * Motor cables with 3.5mm banana connector and crocodile clip 1 * DC Input Power Cable with XT60 connector and 4.5mm banana connectors 1 * DC Input Power Cable with XT60 connector and Tamiya connector 1 * English Mannual
