Helicopter servo calibration device

The present invention belongs to the technical field of detection, it relates to a helicopter servo calibration apparatus. The present invention utilizes the latest technology and frequency WPM test methods, to increase the integration of the instrument, instrumentation increase stability, reduce the volume of the instrument for field use. It may also adjust its neutral position while detecting the steering gear. The present invention relates to dividing resistors and voltage indicator is connected via a digital voltmeter are connected via slide resistance and ± 15V power module integrated voltage, by adjusting the slide resistance of the resistance, the detected steering tilt, pitch and other parameters .
