The Ripmax Xtra Servo Tester is a compact hand held unit with an input of 4.8 to 6 volts and the output checks the servo pulse, end point and trim. There is a manual mode and an automatic mode.

Using the arrow keys, the servo can be made to move through its entire travel range, one step at a time, or centred. The pulse width is continually displayed so that set–ups are quick, simple and accurate.

In Auto mode, the servo can be made to move through its entire travel range automatically. Using the arrow keys, the speed of this travel can be adjusted. Perfect for checking the performance of a servo.
