After setting up the KH Director, I have concluded that the trouble shooting page should add something discussing dosing pump issues. In retrospect, the issues that I was having from the beginning of my attempts to set up the silly device had nothing to do with the KH Director and instead was related to the dosing pumps. The water sample line and the reagent lines were not able to keep prime and the problems that I was having in set up were all related to that, but at the time I did not know it. I kept fiddling with the KH Director and not the dosing pump.
If the results of the KH Director are inconsistent, then I think the problem may be dosing pump related.
When I got the pumps straightened out, and got everything set up and running correctly, the KH Director immediately starting giving the same result which was 6. This was a substantial difference to my Hanna Checker which was giving a result of 8.3.
By this time, I figured that I did not accurately set up the calibration of the dosing pump. So instead of re-calibrating since I figured my measuring cup was off, I decided to increase the amount of ml per minute. I did this until the result of the KH Director increased to 8.3.
Then just to make certain that my result is accurate, I ordered a bottle of effluent that I can compare against.
This may all seem like a backwards way to get to the same result. But this is what I did.
