Feature: 1. Synchronous output servo system and servo performance for precise control servo and the output signal. 2. Test for subtle changes in each steering gear. (1 millisecond = 1000 microseconds). 3. Rotational potentiometer can reduce or increase the width of the output pulse. 4. 800‑2200us Signal width and 4.8‑6.0v working voltage, multi‑functional RC tester. 5. Suitable for remote control car, boat, airplane, brushless and brushed ESC servo testing. Specification: Condition: 100% Brand New Item Type: ESC Tester Material: Plastic + Electronic Components Color: Blue Size: Approx. 75 x 38 x 15mm / 3 x 1.5 x 0.6in (main part) Working Voltage: 4.8-6.0V Signal Width: 800-2200US 1. 50H analog servo signal cycle 20US frequency 50HZ 2. The signal cycle of one 125H digital steering gear is 8US frequency 125HZ 3. 250H digital servo signal cycle 4US frequency 250HZ Scope of Use: Synchronous output control signals can be used to test the synchronization capability of multiple steering engines, or the rotation speed difference of steering engines. It can accurately output the signal and test whether the steering gear can respond to the tiny pulse signal. It can test the electric adjustment and simulate the oil pushing action of the remote control. Usage: Power into manual mode automatically, you can turn the knob to adjust the width of pulse signal. Select key Toggle function (neutral, automatic, manual) Frequency switch key: Cyclic switching frequency (50Hz/125Hz/250Hz) Analog steering gear: 50HZ Digital steering gear: 125/250Hz Quantity: 1 Application: remote control vehicle/ship/aircraft brushed brushless ESC, motor etc. Note: 1. No backconnect protection, do not backplug power supply. 2. Digital or analog signals should adjust the button to select the corresponding servo system, and then plug in the steering servo to avoid damage to the server. 3. When testing the steering gear, the power supply should be connected to the voltage, and the output should be connected to the steering gear. 4. When measuring the electrical and mechanical adjustment, the power supply does not need to be connected to the voltage, and the electrical adjustment signal line is connected to the output end..
