AA cells 8 Copyright InnovAg 1996 2003 1 What is MiniTest MiniTest is a small light hand held instrument for testing vacuum supplies and pulsators in dairies It uses the same high accuracy analysis of its big brother DairyTest Professional but in a smaller lighter lower cost format It is intended for use by personnel with technical knowledge of dairy operation as an accessory to a professional test kit i e for bench testing of pulsators and to do a quick check on the dairy s performance It has only a single vacuum port and cannot be connected to a PC or printer Within Australia we have a Freecall help line which is there if you have problems 1800 061 167 International users should call their local distributor or contact us via fax 613 9521 8009 or email innovag cpdesign com au Copyright InnovAg 1996 2003 1 2 Safety Precautions MiniTest is intended to be used in the milking stall always allow for the unpredictable nature of the animals During the measurements sharp needles may be used Take care they do not hurt people or animals Always ask the dairy farmer about the behaviour of the animals and milking method used If using MiniTest in wet tests always keep the unit above the test point to prevent fluid entering 3 Maintenance and Calibration Maintenance Clean the MiniTest with a moist cloth Do not use cleaning agents The MiniTest performs a self test when turned on ligh2.
