Re: Calibration for analog sensor (voltage, resistance and NTC sensors)

I have sensor points like: +2C = 4V ; +7C = 3,5V ; +90C = 1,2V
How I`ll know the constants? I tried to find out them by excel: http://reveltronics.com/downloads/adds/NTC.xls
but when I put them into utcomp, results were terrible.. :?
Can You help, please?

Re: Display flashing problem

Exactly, the longer tape. I changed tape to ~2,4 m tape, because i needed to place it to overhead console.
Is there problem, that resistance from utcomp to display is too big, or some another problem?
Can I somehow overcome it?
Thanks for info!

Display flashing problem

Hello to all! Have problem with utcomp-pro oled-display, it flashes with frequency about 1 Hz all working time :( , but before shutting down, there is a summary picture about 5 sek. and this is still picture(not flashing). Does somebody already solve this problem? What can cause like behavior? Thank...
