Greetings I'm new at this meter reading stuff, but I also know that I need to take alot of the quess work out of my work aswell so. Hanna HI98312 Question Can any one tell me something about “Conversion setting” The setting is adjustable and I can’t find any thing telling me what it should be set at. Instructions tell me to "set Conversion factor" (“CONV”) it was set @ .50 but it can be set from .45 to 1.00 And then it say's to Set “BETA” it was set @ 1.9 but can be set from 0.0 to 2.4 Man this is confusing but I know this has got to be correct, operation instructions only say how to change them but not what they should be set at. ANY Help?
