Question

LabQuest freezes after many drops with drop counter

Answer

In LabQuest App version 1.0, it was possible to exceed the LabQuest memory by doing an experiment that includes many (more than 1700) drops through the drop counter. If this happens, you will need to reboot the LabQuest, see:
TIL 1777: How do I reboot a LabQuest?

The memory management is significantly improved in LabQuest App version 1.1 and newer. Our testing shows you can now collect in excess of 5500 rows of data, which is equivalent to 200 mL of titrant (at our default ratio of 28 drops/mL). It is unlikely that this volume will be exceeded in an experiment.
