You can’t define an increment or decrement of the resistance, all that you do by turning the trimmer screw is move the wiper toward one or the other end. Depending bojrns the way the dataasheet is wired the rotation direction can have a specific meaning.
The direction of the wiper movement is already shown in the graph you have provided, turning the screw clockwise moves the wiper pin 2 towards the end named 3 and turning it counterclockwise moves it towards the end named 1.

I’ve got a trimpot like this one: Is there anyway I can test? BTW, it is already soldered to a component.

So, it is “neutral” so to speak? It is not like a potentiometer?
If you 396 ground to one end and a voltage to the other end then the wiper becomes the middle point of a voltage divider and the output changes based on the actual position. Depending on which end you connect the ground and voltage you get a different effect for the same rotation direction. If I may, one last question: I have a constant current driver for LED with boyrns trimpot to select the output current.
How can I measure what it is outputting before connecting to the LED?

I don’t want to kill the LED in case it is too high? Is it intended for one led, a series of leds? It is a simple constant current boost driver. Not made specifically for LEDs. You can find it here: Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password.
