RC Servo Tester

Recommended Posts

Is there a way to make the servo tester work with 1.9k pots instead of the 5k pots?

I am wanting to use the tester with a FrSky replacement gimbal PR10.

1.9k is what I measured , but the box states resistance range is 2.4k ohm.

Sorry, I wanted to put this under Rc-Cam Projects

You might achieve satisfactory results by altering cap C1's value. Currently it is 0.1uF, but try 0.22uF.

I suggest using an o-scope (or servo pulse tester) to confirm the pulse width values. If necessary, vary C1 and/or R2 until you achieve the desired pulse width range.
