i bought circuits and probes from Atlas Scientific for PH, ORP and Density.
Unfortunately it is absolutely not clear to me how I can perform the probes calibration.
Should I use the test code? because I loaded it and everything seems ok, every channel I try to open is ok. But I really don't know what I should do for the calibration.
I also read a thread by Sueur Aurelein but it is not clear to me.
Can you help me?
