【文章內(nèi)容簡(jiǎn)介】 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 3090 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(xiàng)：1)本儀器使用于常溫環(huán)境下10 ～ 30 ℃2)測(cè)定時(shí)必須裝上保護(hù)架，否則測(cè)定粘度將因容器的直徑變化而變化。3)轉(zhuǎn)子在安裝和拆除時(shí)應(yīng)將轉(zhuǎn)子連接螺桿向上抬起，避免轉(zhuǎn)軸軸尖碰損，浸入液體時(shí)避免氣泡粘附于轉(zhuǎn)子上。4)儀器不得測(cè)放或倒放，特別是在裝上轉(zhuǎn)子時(shí)。5)裝上轉(zhuǎn)子后，不要在未浸入液體的情況下，開(kāi)機(jī)旋轉(zhuǎn)。6)每次使用完畢小心拆下轉(zhuǎn)子，徹底清洗，用吹風(fēng)機(jī)吹干，垂直安放在轉(zhuǎn)子架上。7)搬運(yùn)儀器時(shí)應(yīng)裝上黃色包裝套圈和橡皮圈鎖定指針鎖定桿。8)直接測(cè)定被測(cè)液體的，不要以恒溫槽的溫度代替被測(cè)液體的溫度。9)在測(cè)試中非牛頓液體的表現(xiàn)粘度往往因切變速率和測(cè)定時(shí)間長(zhǎng)短等因素的不同而變化，屬正常情況，非儀器故障。10)嚴(yán)格按照使用要求操作使用。Points for Attention：This instrument should be used in regular temperature(Normally 1030 ?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 immediately (don39。t clean the rotor when it is on the instrument). After cleanin
