By pressing [MEDIA], the “Media” LED will blink green
and a volume of about 20 mL be dispensed into the
tared container.
When the “ml” LED is flashing green, the user is
prompted to enter the volume dispensed (measured by
weighing the container after dispensing) using the [+]
and [-] buttons and the [DECIMAL] button to select the
digit to be changed. Press [ml] to confirm.
The peristaltic pump will then be calibrated with this
value.
The value must be between 18 and 23. If not
please check that the balance was properly
tared and calibrated. If the value is still not
in the range, ensure the tubing is properly
placed in the pump head.
In case of an issue during a calibration step,
press [CANCEL] to restart calibration.
An orange blinking “Water” LED informs you that a
flushing step is required to remove the concentrated
media remaining in the dispensing tubing.
Press the [WATER] button to start the flushing step.
When the “Water” LED is blinking green the user is
prompted to stop the water pump.
Make sure to have a container on the
dispensing unit to collect the dispensed water.
If for any reason the pump head is opened,
the calibration of the peristaltic pump has to
be repeated.
Water pump calibration status check
If flowmeter recalibration is due within 24 h, the system
will propose to perform the calibration before entering the
media dispensing mode. If recalibration is due within 1h, it
is not possible to skip it.
If confirmed, the calibration is performed as per the
workflow previously described. (see Water pump flow
meter calibration in the chapter: Setting up the instrument
and consumable on page 18)
Water pump flow meter calibration can
be initiated by pressing [WATER] for 3
seconds during routine usage whenever the
instrument is not dispensing. This will reset
the 7 day calibration timer.
If more than 100 L are dispensed per day, a
recalibration after 500 L is recommended.
