•
Do the same action with the other font if needed. If only one font is calibrated, settings for
the other will not be altered.
•
The minimum time possible for the time dispense operation is 1s. Setting the dispense time
for less (quick font button click) will set the font back into "push & hold" mode.
•
After the volumes are set properly press the tactile button on the timer board once again.
•
Both pumps will turn on and off for 0.1s twice - that will be heard as a double click meaning
that the timer is out of calibration.
•
Please note that there is no given order which font is to be calibrated first - in fact they may
be calibrated at once or only one may be calibrated (leaving the settings of the other
unaltered).
•
If there is no response from the user in the calibration mode (none of the font buttons
pressed) for more than 25 seconds the timer will end the calibration (double pump "click"
will be heard).
•
The maximum allowable time of dispense is 25 seconds. Any longer times will be cut down
to 25 seconds.
•
The resolution of the time measurement is 0.1s.
•
The timer board has its own clock on board therefore power line frequency is not used to
measure the time.
