Rctime and ntc

[Archangel]

Wow, having never used RCTIME I am flying by the seat of my pants here (as Usual), but you are able to approximate the resistance (you do the math) of your NTC and from there I would make a lookup table to output the value, based upon the specs of the thermistor (published table?) and your own recorded values. For instance if your RCTIME results are 1200 and your NTC is 200 F and it if it is 600 @ 32F then you can start that table. Again compare how your results track the published specs.

I tried to do a reading at 27 degrees and 128 with me RCTIME command.
How can I convert that value.

compare your readings & subtract, multiply or divide the difference by 101/100

Ok thanks for your response. I made a table and I got 367, 6 ° C and 67 ° C with 80 now you suggest I split the valiri for 101 or 100? I did not understand. sorry but I write with a translator because I'm Italian. hello

the 100 & 101 are percent based upon your sample spread what you need is the ratio of reading per degree, you can divide it or use a lookup table. The lookup table is more tedious but can be adjusted to calibrate results. The numbers I got were 287 & 4.377, 4.377 per degree. Round it up to 4.38
multiply everything by 100 and divide. Check div32 function.
