I have noticed recently that my KH Director results drift downwards over time, it usually goes down by 0.1-0.2 dky per day.
After finally having the time to have a look at it I have realised that if I flush the measurement cell the result goes back to the correct value in line with my other test kits but start drifting down again.
I am assuming this is caused by something I have set incorrectly but I can figure it out, does anyone have any ideas?
