EV3 not recognizing resistance correctly (MicroPython)

[C-Brick]

I recently tried measuring the resistance of a thermistor using the .resistance() method, the results are sadly not accurate. I measured the resistance with a multimeter and it showed 100kΩ, while the different EV3's all showed something between 330kΩ and 360kΩ. Even with no resistance the EV3 shows around 10kΩ resistance, so the results are not off by a fixed amount, but the results are repeatable.

Here  is the code I used:

#!/usr/bin/env pybricks-micropython

from pybricks.hubs import EV3Brick

from pybricks.iodevices import AnalogSensor

from pybricks.parameters import Port

 

ev3 = EV3Brick()

 

termistor = AnalogSensor(Port.S1)

 

x = termistor.resistance()

 

print(x)

Any help, explanation or like a formula to calculate the real resistance would be very appreciated 

Thanks

Hey, could you show a photo about what sensor you're speaking, and what/how it's used? I don't know at the moment the sensor you're speaking about, but maybe if you can show us, we can try to help.
