Description: Weight: about 8g Dimension: 42.5 * 24 * 23.5mm Consumption:15mA(Current 5.0V) Voltage consumption: DC4.5-5.5V Static current:3mA (5.0V) ta=25 C output Signal:1.5ms0.5ms Manual pulse width adjustment Specification: Test device can easily detect the clearance, jitter and median of all kinds of Servo (server) It can easily connect the ESC and test the working status of the ESC or Motor It can connect three sets of servo or ESC at the same time, use SCM to control with Good stability, high accuracy Usage: Power Supply:4-5 pcs of #5 battery,ESC built-in BEC or UBEC TO Provides power to the tester.When you use the ESC with built-in BEC,No additional power supply need,connect the servo or ESC that you want to test to begin testing. Test Mode:There are hand conditioning pulse, the neutral point output function and automatically adjust the pulse width ,you can toggle switch to select one of three models to test.when you use manual adjustment the knob can work,you can adjust the Output pulse width or the ESC or control servo Arbitrarily.The Neutral point is used for finding the middle point of the servo.Automatically adjustsment can make the servo Rotate back and forth. Notice: when you test the ESC,you can only use the manual mode Package includes: 1 x Servo Tester
