10.
Initial Operation / Turning the Device off / on
Before being turned off the device must be cleaned in order that no milk
residues can remain in the device.
Zero calibration has to be performed after the warming-up. The zero calibration
lasts approximately 5 minutes.
11. Initial Operation / Zero Calibration 6 minutes
After the warming time up the zero calibration
can be started.
Starting zero calibration:
a) Place the sample suction tube in a sample
glass filled with the “ -

-FUNKE GERBER
FUNKE GERBERFUNKE GERBER
FUNKE GERBER Zero-
Diluent“. There should be at least 50 ml of
liquid present. Otherwise the device would
draw in air, which would then call up the error
message “No Plateau”.
b) Use the arrow keys to select the “Zero-Cali”
menu item.
c) Press the “Enter” button -- zero calibration
starts. Progress is shown by means of a
moving bar.
Zero calibration is used to calibrate the hardware. It is not calibration of the
substances in the milk. This is performed with the B calibration. If you would
like to check the zero calibration process, please carry out a control
measurement with the “ -

FUNKE GERBER Zero-Diluent“ as you used before
doing the Zero-calibration. For this control measurement profile 0 must be
used. Profile 0 cannot be calibrated and is therefore suitable for this control
measurement.

3. Sample suction tube
The suction tube should be inserted at least 30 mm deep into the milk sample.
The suction tube can be removed from the milk sample after the suction process
unless several analyses have been configured.
4. Pump
The pump discharge in a common line, which runs first through the
measurement cells and afterwards into the waste hose.
The sample taken from a milk sample container is not pumped back there. The
sample quantity taken approx. 10 ml is thus not
available for further examination.
The pump head is located on the left side of the
instrument. As this is a hose pump, the pump head
must be replaced from time to time. This is a
consumable part which can be obtained as Item No.
3530-023 A. We recommend replacing these pump
head at least once per year, possibly more often
depending on usage.
5. Replacing the pump head
The following steps must be taken for replacing the pump
head:
5.1. Remove the pump head: Press both plastic lugs
simultaneously and remove the pump head.
5.2. Undo the hose connections: Detach the hoses from the
hose connectors.
5.3. Install new pump head: Move the new pump head
carefully onto the motor axle. Press further until the plastic
lugs engage in the holder.
5.4. Connect hoses: Trim the hoses to the correct length
and push the hose ends onto the respective connectors.
Please ensure that the hoses are not too long.
