I cant figure out which pin is the number 1 on the potentiometer and variable resistors within this schematic. I would guess that the circle with a slash through it is pin one but I'm not sure. Any help would be appreciated. Thanks in advance!!! Schematic link below.
Trimpots especially multi-turn pots are often numbered with pin 1 being the CCW position and 3 for CW.
Since it is not marked (as one would hope) on the schematic, you may hope what see is the minimum position is pin 1 (CCW).
This "standard" was started by Bourns and but it's hard to say if it is still universal.
