A quick titration with the step motor burette gives stuttering. How do I prevent this?

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):

  1. Start the Coach activity ‘Acid-base titration with CMA burette’, or comparable.
  2. In the Program window, just below its title bar, drag the window edge down to open the procedure editor.
  3. Increase the value of the variable WaitingTime (for instance into 0.005).
  4. Drag the edge back to close the editor window and retry the activity.
