I am still trying to figure out the calibration of the blue lab and how to use this thing properly. I still don't understand the different PPM reading (weather the .5 or .7 conversion). Which one should I use, when USing the LUCAS formula?
I know meter gives you the conversion - ppm or CF and you know the value. So taking a look at my meter, EC 1.0 = CF 10 = 700 ppm (ECx700) = 500 ppm (EC x 500). The one reading gives you the four values depending on which column you are reading on the meter.
Here is their conversion chart:
