Page 2 (cup) with two metal electrodes Mastitis - inflammation of the udder - is one of the most important and costly problems in dairy farming. Subclinical states of mastitis are particularly dangerous. In this state, milk looks normal and the udder or quarter affected appears healthy.
Page 3 2. Model: 4Q MAST 3. Model: 1Q MAST The device consists of a one measurement vessel (cup) with electrodes, electronic unit with LCD panel, handle containing a standard 9 volt battery marked as: 6F22 and a The device consists of a one measurement vessel (cup) with electrodes, electronic unit switch.
Page 4 OPERATION 2. Model: 4Q MAST The display indicates the proper work of the device. The first checkout of the detector 1. Model: 4x4Q MAST should be conducted with no milk in the cup, in the ‘empty air’, when electrodes are spaced.
Page 5 The measurement range of the device significantly exceeds the maximum resistance of the milk tested. Therefore, in practice, it is never reached. NOTE ! The MASTITIS DETECTOR (all models) is not intended for the measurement of pooled milk. The device should be used only for measuring milk collected...
Page 6 Measurements are made in the following way: 8. The detector is automatically switched off after 30 seconds of idle operation following the last pressing of the switch. Model: 4x4Q MAST The device may be also switched off by pressing and holding the switch for more than 3 seconds.
Page 7 A difference exceeding 40 - 50 units between the highest and the lowest result obtained for quarters in a tested cow indicates the onset of subclinical mastitis. It After a cow has been tested it is recommended to note the principle conclusion or is necessary to examine the cow systematically before each milk yield, and mark it with a symbol.
Page 8 The method of the measurement of changes in milk device is of utter importance. impedance may be used for the detection of the early stages of Mastitis Degreasing (cleaning) of electrodes should be performed before each session of subclinica.
