Settings for multiple variable resistors in a logic probe

I am building what looks on paper like a really sweet logic probe as a first project. It includes 3 variable resistors. The site I got the circuit diagram from is translated into english and doesn't make sense. There is some nonsense about low current measurements.
My do I determine settings for the various resistors?Settings for multiple variable resistors in a logic probe

Also, can I assume VR1 at the top is, by convention, 50K?
