Warning！
Do not power on before the 2 operations above, otherwise damage will be caused.
f. Power on, make adjustment of the support stand and make sure the leveling bubble is in the center.
3. 操作：
1） 首先將保護架右旋上儀器下端。
2） 準備被測液體，選擇直徑>or=70mm 的圓柱型容器。
3） 按測量要求的精度，準確控制被測液體的溫度
4） 估計被測液體黏度值的大致范圍參考量程表選好轉子號，并將轉子左旋入連接螺桿（圖4）.然后旋轉升降鈕（圖5），使儀器慢慢地下降，逐漸浸入測量液體中，直至轉子液面標志和液面平為止。（圖4）按下指針鎖定桿，開啟電源開關，放開指針鎖定桿，使轉子在液體中旋轉，一般20~30秒的運轉，待指針趨于穩(wěn)定。按下指針鎖定桿，使讀數(shù)固定下來，再關閉電機，使指針停在讀數(shù)窗范圍內(nèi)，直接讀出數(shù)據(jù)。當電機關停后，如指針不處于讀書窗內(nèi)，應繼續(xù)按住指針鎖定桿，反復開啟和關閉電機，使指針處于讀數(shù)窗內(nèi)。如選用6和12轉/分時，可直接讀取讀數(shù)，不需鎖定指針。
5） 讀數(shù)指針一般在30~90分度之間為佳，否則可變換轉子號和轉速達到這個要求。
6） 當不能預知被測液體粘度值時，應試用由小到大的轉子和轉動變速鈕（圖5），由慢到快的變化轉速順序來測定粘度值。
Operation：
1） Firstly，Spin the protector pole to right just right under the instrument.
2） Prepare the fluid to be measured ,put it in a beaker or cylindrical container with its diameter not less than 70mm.
3） According to the requested precision of measurement, the temperature of the fluid to be measured should be precisely under control.
4） First estimate the approximate range of viscosity of the fluid to be measured, then select the appropriate rotor and speed according to table of range. Screw the selected rotor into the connecting worm（Turn left to install and right to remove）.Turn the elevation knob, slowly lower the instrument, the rotor will gradually dip into the fluid surface, then adjust the leveling speed changing knob making the required speed upward to align with the indication point for speed, release the indicator control rod causing the rotor to rotate in the fluid. After several rotation（Generally 20-30seconds） until the indicator tends to be stable（or make readings at specified time）.Press indicator control rod（Caution: 1. Do not use excessive force. 2.When the speed is quite slow, it is not necessary to use control rod. The readings can be directly made）, causing the reading to settle, switch off the motor, the indicator will stay at the readout window and then reading can be taken. After the motor has switched off but the indicator does not stay at the readout window, press the indicator control rod continuously and repeatedly switch off the motor. After several practices the user will skillfully manage the technique of keeping the indicator too stay in the window for reading.
5） When the value indicated by the indicator is too high or too low, change the rotor or speed so the reading is preferable range of 30-90 graduation.
6） When the approximate viscosity of the fluid to be measured is difficult to estimate, suppose a higher viscosity first, then try the rotor of lower No. to higher No. and lower speed to higher speed. The principle is that for the fluid of high viscosity select small rotator and low speed. For the fluid of low viscosity select large rotor and high speed.
4. 注意事項：
1） 本儀器使用于常溫環(huán)境下 10 ～ 30 ℃
2） 測定時裝上保護架，否則測定粘度將因容器的直徑變化而變化。
3） 轉子在安裝和拆除時應將轉子連接螺桿向上抬起，避免轉軸軸尖碰損，浸入液體時避免氣泡粘附于轉子上。
4） 儀器不得測放或倒放，特別是在裝上轉子時。
5） 裝上轉子后，不要在未浸入液體的情況下，開機旋轉。
6） 每次使用完畢小心拆下轉子，*清洗，用吹風機吹干，垂直安放在轉子架上。
7） 搬運儀器時應裝上黃色包裝套圈和橡皮圈鎖定指針鎖定桿。
8） 直接測定被測液體的，不要以恒溫槽的溫度代替被測液體的溫度。
9） 在測試中非牛頓液體的表現(xiàn)粘度往往因切變速率和測定時間長短等因素的不同而變化，屬正常情況，非儀器故障。
10） 嚴格按照使用要求操作使用。

Points for Attention：
This instrument should be used in regular temperature（Normally 10-30 ?C）.
The protector should be applied in the course of measurement, otherwise the viscosity will vary with the diameter of the container.
Care should be taken in installing and removing the rotor. To install and remove the rotor the connecting worm should be slightly lifted to avoid he shaft tip damaged.
When the rotor is installed, the instrument should not be placed on its side or upside down.
After installation of rotor do not power on in the case that the rotor is not dipping into the fluid.
After each operation, clean the rotor immediay （don't clean the rotor when it is on the instrument）. After cleaning, put the rotor on the rotor rack properly.
When moving or transporting the instrument, use a rubber band to wrap the indicator control rod and keep it tightening, sleeve it into the yellow packing ring and lift the connecting worm.
Precisely control the temperature of the fluid to be measured.
Most of the high viscosity fluid, such as suspension, emulsion, high polymer, etc., are usually "Non-Newtonian fluid", their variation of viscosity is according to the shear rate and change of time. Therefore measurement under different rotor, speed and time may give non-uniform results. This is normal, and it is no the fault of the instrument.
Strictly adhere to the operation instructions for measurement.

系 數(shù) 和 誤 差 修 正

1.測定時指針在刻度盤上的指示值乘上系數(shù)表中的系數(shù)值，得到測量液的粘度值。

2.頻率誤差修正（運用正常電網(wǎng)一般不用修正）

“牛頓型流體” 和 “非牛頓型流體”

流體可分為“牛頓型”如：硅油、機油、甘油等。“非牛頓型”如：油漆、乳膠、橡膠、塑料、涂料、膠粘劑等。

在測量過程中如果被測流體的溫度，環(huán)境溫度，樣品杯口徑大小和是否安裝保護架等情況的變化下，則“牛頓型”和“非牛頓型”流體及粘度值都會隨之變化。如果以上幾個條件都不變，但測量的轉子，測量速度和測量時間變化，對于“牛頓型”的測量結果是基本接近的，其粘度值稱之粘度。但對于“非牛頓型”測量結果是會變化的。也就是說在測量“非牛頓型流體”時轉子和速度是不能互換的，其粘度值稱之表現(xiàn)粘度。因此在測量“非牛頓型”時要根據(jù)自己樣品的情況規(guī)定轉子，轉速及測量時間。以免誤解為粘度不準。
