OPERATION

The display indicates the proper work of the device. The first check-
out of the detector should be conducted with no milk in the cup, in
the 'empty air', when electrodes are spaced. After pressing the button
four column of dashes are displayed indicating the device readiness
to work. Now the consecutive milk quarters can be measured.
Blinking dashes indicate the column where the results from specific
milk quarter will be shown. To take a measurement the milk is to be
poured in and the switch pressed.

After the switch is pressed, the flashing dashes disappear, and result
will come up in specific numbers. Next, the flashing dashes will
appear in the next column. Similarly all other measurements from
the next quarters will be done.
Additionally, the display indicates the exhaust state of the battery. A
flashing battery symbol signals that the battery is to be replaced.
10 units is the lowest result possible whereas the measurement
range is 10-990 units. After the level of 990 units has been exceeded
dashes are shown on the display (the same symbol as in the case
when the device tried in the 'empty air'.
The measurement range of Mastitis Detector exceeds the maximum
conductivity value of tested milk considerably. It means that actually
it will never be exceeded.
NOTE ! You must not use Draminski Mastitis Detector for the
bulk milk.
A minimum of 15 ml of milk (indicated by the line inside the cup) is
required, and the sample must be first foremilk for accurate readings.
Later milk samples will give slightly different readings.

Before starting your measurement the following should be
done:
1. Check the work of the detector in the 'open air' ensuring that
the battery is fully charged.
2. Ensure that the electrodes in the cup are clean. Contamination
of electrodes with skin-oil from handling or examination while
on display in stores and/or dried milk-fat can result in
incorrect (high) readings. If required, wipe the electrodes with
methylated spirits on a clean cloth or tissue, or similarly with
kitchen detergent and rinse off.
3. Prepare a bucket full of warm water for rinsing the cup after
each measurement. Additionally, another empty bucket will be
useful for pouring out the milk from the cup after the
measurement. To comply with the hygienic regulations you
must not pour the milk out on the cowshed bedding.
Easy test to check whether the electrodes are clean:
a) prepare a solution – pour a pinch of salt into a glass of water
(of room temperature) dissolving it completely.
b) fill out the cup with the solution and read the result (it depends
on the solution concentration.
c) Pour out the solution into the glass and clean thoroughly the
electrodes with a tampon moisten with the liquid for washing
the dishes. Rinse the cup under the tap shaking the water
remaining off.
d) pour the solution into the cup again and read the result. If there
is a remarkable drop in the result in comparison to the previous
measurement it means the electrodes were coated with fat.
e) the best is to repeat cleaning procedures until it is sure that the
results do not change any more. The latter means the
electrodes are now clean. Note that even touching the electrode
with a finger may contaminate the electrodes.
It is highly recommended to clean the electrodes once a
week be he means of washing powder . It will remove all
remaining from the cup surface.
