Does the ghl doser 2.1 dose while reading empty?

[pwidmer86]

I just checked my alk and it was a little low tonight (.4 dkh lower than typical), I checked my doser and realized that the fill levels were reading empty since I forgot to mark them as refilled when I filled up the containers a few days ago. My question is, will the ghl doser stop performing its regular dosing schedule if the associated container is reading %0 full?

The dosing pumps continue dosing even when the level is empty. Only the KHD checks the reagent level before a measurement is started.
