Hummm I posted this in the general area but know one answered. So I will try here. 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?
