Hello

My KHD has been up and running for more than 2 months now only for monitoring. Alkalinity control was done manually. No issues on the alkalinity accuracy, repeat-ability and it constantly match to Salifert test kit within 0.3 dKH.

3-4 days ago I am letting the KHD to control my alkalinity via Add-On mode. My preferred alk is set at 8 dKH but since letting KHD to take over the alkalinity has swing between 6.3-10.8 dKH.

Some details:
Add-On mode with Nominal dKH value is at 8dKH
It will takes 88ml-ish Fauna Marin alkalinity solutions to raise 1dKH
"Limit for raise KH" is set at 88ml
"Limit for lower KH" is set to 88ml
KHD measurement at 7am and 7pm daily
Doser 2.1 pump 2 in used for alkalinity solutions at 16 times a day.

Questions:
If I understands the manual correctly, setting such value for "limit for raise KH" and "Limit for lower KH", I am letting KHD 7-9 dKH for alkalinity bias for it to control. Am I correct on that assumptions?
Is there anyway can I retrieve Doser 2.1 pump 2 historical dosing amount?
Says at 7am KHD measures 7dKH, theoretically KHD will instruct Doser 2.1 pump 2 for 88ml additional alkalinity solution. Does this extra 88ml addition fluids is spread out evenly till the next KHD measurement at 7pm or it will dump it in one go during the next scheduled dose?

Thanks
