A servo motor tester, as the name suggests, is used to test servo motors. It is a small device with input and output pins, a knob for adjusting the values and light indicators. Although, servos can be tested through arduino boards, but its not always feasible. That is when servo motor testers come in play.
How to use
The servo tester first needs to be connected to the DC voltage source through the pin in its input header. Once done, the light indicator of one of the modes would be ON. Then, you can connect at most 3 servo motors together. The motors should be connected to the horizontally lined up pins. Then, there are three modes of testing that could be toggled by pressing the mode selection switch. The modes are as follows:-
1. Automatic
This mode makes the motor rotate to and fro on its own. It can be used to check if the motor is rotating to its complete potential or not.
2. Manual
In this mode, the user can rotate the motor according to their choice by adjusting the knob. This also serves the same purpose as the automatic mode, except the fact that this is manual
3. Neutral
This mode brings the servo motor to its neutral position, which can be used to determine if its alignment is proper in neutral position.

Common Applications
The major application of servo motor testers is to test servo motors to see if they’re working desirably.
Some example projects that students can try out in the ATL Lab
Take two or three servo motors and test them using the servo motor tester.
Safety Measures to follow
1. Only use compatible voltage supply with the tester.
