3 TEST FLUID FOR WATER TESTS
To preserve the test liquid for the water tests, mix 45 ml Neoagrar with 15 l
Water. This mixture should have a conductivity between 5.5 and 6.5mS.
4 SETTING THE LC T-T IN STABLE
The LC T-T can be hung with hanging brackets or plug-in brackets or
positioned in the stable.
The devices should hang as vertically as possible.
The hose guide is important. The hoses should be as short as possible. The
Milk must always be able to drain completely. Standing milk would distort
the result of the measurement of the LC T-T.

6 Problem of a not completely empty LC T-T
Very low levels cannot be measured exactly, as the output of the pressure pipe is not
completely covered with liquid. After emptying, an empty LC T-T is assumed. If the LC T-T
is not empty at the start of the measurement, errors in the milk quantity measurement will
result.

7 Add the amount of the gap to the total quantity of milk?
It depends on the measurement procedure if the content of the sampling may be added on
the LC T-T for the total or not.
7.1 Milk quantity measurement and sampling at the same time
Where sampling and milk quantity measurement are carried out jointly, the
amount of milk split off from LC T-T may be added to the quantity of milk.
7.2 Checking the quantity of milk
The test of the quantity of milk may be carried out without sampling.
If the milk quantity measurement is carried out with sampling, usually the milk in the
sampler will be emptied in the bucket of the current milking. In this case,
the addition of the release quantity to the quantity of milk must be active.

8 Calculation of the amount of milk when measured without
emptying
If the milk quantity measurement is checked without emptying, the remaining volume
(difference volume) in the LC T-T has to be taken into account.
The storage level in the LC T-T is always different at the end of a measurement. This milk
quantity difference that must be taken into account.
The LC T-T measures the storage level of the milk at the beginning (starting level) and at
the end of the Measurement (final level). In this manner the weight of the milk, which
remain in the LC T-T, will be added to the amount in the bucket. When counterweighing, it
is necessary to add this milk, which is left inside in the LC T-T, is taken into account in
order to guarantee the effective quantity of milk from the animal. The LC T-T quantity and
the weigh can be compared as follows:
Lc T-T Quantity = "milk in a bucket" + difference = quantity of milk of the animal

10 Possible errors and their solution
10.1 Error: No filter inserted. Measurement not possible without filter
This error is displayed when starting up and starting the measurement when in the
LC T-T no filter is inserted. Either the filter is missing or the magnet in the filter is not
inserted.
10.2 Display by measurement: Storage Online. Failed!
For computing capacity reasons, the LC T-T does not have the option of making a PC
error in USB communication. Therefore, it may be possible that a USB stick on the PC
can still be read, but the LC T-T displays an error message. In this case, the USB stick
should be replaced.
If there is an error when writing the online data to the USB stick, it must be repeated or
canceled. If this has been aborted, it can be transferred to the measurement data on the
USB stick. Only then new online data can be recorded.

10.3 Cleaning takes longer than there is space in the online data
A maximum of 90 min. online values can be recorded during a cleaning process.
If a cleaning takes more than 90 min. it will indicate that a RAM overflow has occurred and
that the online readings are not complete. In this case, the first 90 min. of the cleaning
were recorded. This only applies to online values. Cleaning continues normally.
11 Data transfer to LactoPro
The measured data can be analyzed in LactoPro.
This should be used with LactoPro version 6.0.90. This version can be obtained from
WMB or from the website: www.wmb.ch/LCT-T/lactopro
11.1 Data on the USB stick
The measurement data from the LC T-T is displayed on the USB stick in the folder "LCS
measurement data". If this folder is not already available, the LC T-T will automatically
create one. The measurement data file is made up of the abbreviation MD for
measurement data, the operating number and the date when operating data was written to
the LCS. If no operating data has been used, 0 is entered.
e.g.: MD_1234567890123456_121115.DAT
MD: Identification for a measurement data file
1234567890123456: Operating number
121115: On 12/11/2015 the operating data on the LC T-T
were loaded
11.2 Transferring data to the PC
The desired measurement data file must be copied manually in the LactoPro folder in the
following path:
".. "LactoPro\Daten\Datapack"LCS_Messdaten"
The LCS_Messdaten folder must be created manually once.
The program "LactoPro" can then be started. The reading of the LC T-T measurement
data is now the same as reading data from a data pack.
Under "Data- Telepack -> Measurement and Operating Data DP -->PC"
The LC T-T data can be viewed like the data from the LactoCorder in LactoPro.
The following values are currently stored correctly:
- Operating number
- Animal number 2
- Bottle ID
- Device number
- Time
- Date
- Milking place number
