HJ Servo Tester

Used to check synchronous output control for up to 4 servos and compare the performance gear control of the servo output signal. It gives accurate value down to 2us(1 millisecond = 1000 microseconds), you can test whether the gear can respond to subtle changes. With the PPM signal test function on the screen, the signal changes as the PPM input enters the PPM signal synchronization output to the servo.
