Thanks I did, but don't know if it's helping me. Can anyone explain the SCL2 function? If I understood corectly there are three parameter words, P1 (offset which is in my case zero), P1+1 (X number of increments - in my case the full scale is 4000 BCD = 0FA0 HEX is what I should enter) and P1+2 (Y full scale conductivity - for exemple 1000 mS/cm in BCD that means I should enter 1000 and not 03E8). To conclude should the last parameter word be entered in BCD or in HEX like two first words?
