What's the resistor that comes with the PT100 board for?

[alexspeller]

I received my PT100 daughter board today, it comes with this resistor:

It doesn't seem to be mentioned in the docs, what am I supposed to do with it?

Thanks,
Alex

@alexspeller It is purely provide so that you can test the Daughter board / PT100 sensor it is a 100 ohm resistor that if you fit to the daughter board in place of the PT100 you should see 0 degrees reported!
It's so you can prove if a misreading is down to the PT100 wiring or the port on the daughter board

Oh cool, thanks!
