　　三、使用方法：

　　?測定環(huán)境：23°C±0.2°C

　　?將儀器從盒內取出置于工作臺邊，使砝碼支架能順利向下滑落到地面。

　　?插上電源插頭，開啟后蓋右下端電源開關。四位顯示器上數(shù)字即顯示為零。同時轉速指示燈亮，該儀器處于檢測轉速工作狀態(tài)。

　　?將被測樣品充分攪勻放入容器內，使液面離容器口約19mm然后放到容器支架上，將轉子浸入液體中，使液面剛好達到轉子軸上的標記處。然后擰緊鎖緊螺釘。

　　?在儀器砝碼支架放上砝碼，松開剎緊把手，轉子即開始旋轉，同時計數(shù)器開始在面板上顯示轉子每分鐘的轉速。轉速如低于200轉/分時，則應增加砝碼重量，超過則減少砝碼重量。此步驟應重復幾次使轉子轉速穩(wěn)定在200轉/分，此時砝碼總重（包括支架30g）為恒定負荷。

　　?按置數(shù)鍵及移位鍵，輸入200轉/分時所加的砝碼總量（g）與顯示的數(shù)字一致。然后在按置換鍵，此時KU值的指示燈亮，顯示器上顯示的數(shù)字即為所測樣品的KU值。（注：移位指示點不能誤認為小數(shù)點）。

　　Third,use method:

　　?Measurement environment:23°C±0.2°C

　　?Take the instrument out of the box and place it beside the workbench,so that the weight bracket can slide down to the ground smoothly.

　　?Plug in the power plug and turn on the power switch at the bottom right of the back cover.The number on the four-digit display is zero.At the same time,the speed indicator is on,ａnd the instrument is in the state of detecting the speed.

　　?Thoroughly mix the measured sample into the container,make the liquid surface about 19mm away from the mouth of the container,then place it on the container holder,immerse the rotor in the liquid so that the liquid surface just reaches the mark on the rotor shaft.Then tighten the locking screws.

　　?Put a weight on the instrument weight support,release the brake handle,the rotor will start to rotate,ａnd at the same time,the counter will display the speed of the rotor per minute on the panel.If the speed is less than 200 rpm,the weight of the weight should be increased,ａnd if it is exceeded,the weight of the weight should be reduced.This step should be repeated several times to stabilize the rotor speed at 200 rpm.At this time,the total weight(including the bracket 30g)is a constant load.

　　?Press the setting key and shift key,input the total weight(g)added at 200 rpm and the displayed number.Then press the replacement key,at this time the indicator of the KU value is on,ａnd the number displayed on the display is the KU value of the measured sample.(Note:the shift indicator cannot be mistaken for a decimal point).

　　四、工作原理：

　　?微電腦控制。攪拌槳葉由特種恒轉速馬達帶動以200r/min的速度轉動，攪拌槳葉在被測樣品中旋轉受到的阻力矩由電腦轉換以KU值（克雷布斯Krebs）單位（KU）產生200 r/min轉速所需的負荷的一種對數(shù)函數(shù)，一般用來標示用于刷涂和滾涂的粘度。

　　?對數(shù)據(jù)進行了計權運算和相關處理，自動刪除偏離中間區(qū)域的數(shù)據(jù)，提高了儀器測量重復性的參數(shù)。操作者只需將攪拌槳葉浸入被測樣品到規(guī)定的深度，即可從本儀器上直接讀取改樣品的KU值和與之相關聯(lián)的負荷值。

　　Fourth,the working principle:

　　?Microcomputer control.The stirring blade is driven by a special constant speed motor to rotate at a speed of 200r/min.The resistance torque received by the stirring blade in the measured sample is converted by the computer to produce 200 r in KU(Krebs)units(KU)/min is a logarithmic function of the load required at the speed and is generally used to indicate the viscosity for brushing and roller coating.

　　?Weighted calculation and related processing were performed on the data,ａnd the data deviating from the middle area was automatically deleted,which improved the repeatability of the instrument.The operator only needs to immerse the stirring blade in the sample to the specified depth,ａnd can directly read the sample's KU value and the associated load value from the instrument.
