In the event of problems, dispensing can be performed
in the test square with the grinder control in use to see if
the symbol * is present beside the flow. Remember that
dispensing is deemed valid only if it lasts more than 10
seconds.
Other symbols are used in the test square:
>
if the flow is too high compared to the reference, above
the upper limit
< if the flow is too low compared to the reference, below
the lower limit
*
flow within the acceptable range
