Description
4 wire resistor standard
The board has a 4 wire setup for measuring resistors. You can have 2 resistors in a series or 4 in a series/parallel setup.
10 kΩ + 10 kΩ = 20 kΩ
10 kΩ + 10 kΩ
= 10 kΩ
10 kΩ + 10 kΩ
10 kΩ + 5 kΩ = 15 kΩ
10 kΩ + 5 kΩ
= 7.5 kΩ
10 kΩ + 5 kΩ
If you populate with just 10 kΩ resistors, you get 10 kΩ, the advantage is you can mix the resistors to get the closest to 10 kΩ.
I have also added an option for a thermister or a 1-wire option for measuring the resistors' ambient temperature.
