Question
I have a MPT10000 and am wondering about the proportional gain: the potentiometer turns endlessly, there is no left or right stop, I want to know how to obtain a value of the set gain, is there a way of getting a 0-5 V readout?
Answer
The setpoint Pgain trim pots are 12-turn trim pots. They do not have a stop at the right or left, but at full-right or full-left you should hear or feel a small “click” to let you know you are at the end of the range. Sometimes this is very difficult to hear or feel so make sure you start at least 12 full turns in the clockwise position to know your starting point.
See the two links below for setting the proportional gain, depending on the MPT you have, Rev D, E or F. For Rev F settings see the Rev E link.
