How do you hook up to VRs? I want to have 1k fixed and 1k for adjustment. the adjustment has 3 pins, one is grounded. Now does it matter on which of hte other 2 legs i put the fixed 1k on">?

Well from what i know, when you adjust a VR both of the side legs change in restance. EG. a clockwize turn will increase te left leg and lower the right leg. Don't hold me to that as im quite noobish.

The basic is to put these resistors between the Vsense and a Ground.
You solder the 1k fixed to the Vsense and solder the other leg of the fixed one to one of the legs of the VR.
Closer how to solder the variable one:
Before soldering it cut one of the outer pins.
Measure resistance and set it to max.
You have to connect the fixed one to the pin where yours red probe was during measuring resistance.
Solder the outer pin, which you didn't remove to GND!
That's it.
Hope my English is good enough.
It would be fine if you could correct my language, that I can learn from me faults and won't do them again.
