MK138 Range Alteration

Hi,

I would like to reduce the operating range of the MK138 to approx. 0 - 10°C.

Can you tell me which components will need to be altered?

Thanks

The board indicates which resistors you should change.
Sorry, no values, please experiment.

Try Lower Values of NTC Thermistor the kit is normally supplied with a 5k6 R thermistor so if you try values of 4k7 3k3 if available you might get down to the 10C you are looking for

Hello,

Wouldn’t be easier to change the resistors as these are easier to find?

The resistors that need to be changed are printed on the PCB.
