If the steps follow each other too quickly, stuttering may occur as soon as the syringe is pressed. This problem appears sometimes when the command Titrate(…;Fast) is used. For a slow titration (Titrate(…;Slow)) the step motor burette should function properly. If fast titration is required, try to increase the waiting time between the steps (only possible in Author mode):
- Start the Coach activity ‘Acid-base titration with CMA burette’, or comparable.
- In the Program window, just below its title bar, drag the window edge down to open the procedure editor.
- Increase the value of the variable WaitingTime (for instance into 0.005).
- Drag the edge back to close the editor window and retry the activity.
