Spinning problem with
the magnetic stirrer bar/
pellet
Widely varying
measured alkalinity
results
If the water mixing magnetic stirrer bar/pellet is not spinning
then in the Cloud Application, under the "KH Lab Settings",
increase the "Stirrer speed" from the default 100 to e.g. 150
or higher, and test it again.
If the water mixing magnetic stirrer bar/pellet is spinning to
fast then can go out of synchronization with kHLab module
and hit the wall and pH probe. As a solution decrease the
"Stirrer speed", and test again.
Make sure that the pumps heads rollers are clean
buildup, dust, or lubricant/grease on rollers. The picture
below shows a pump head with dirty rollers. If rollers are
dirty, remove the dosing pump head and clean the rollers.
You can use a fresh paper towel and alcohol or a different
solvent solution.
