2.安裝:
1) 從包裝箱中取出機箱底座與支柱。
2) 將三只水平調(diào)整腳旋入底座螺絲孔中(圖一)
3) 主機安裝:
a. 旋松機箱中螺釘取出主機。
b. 旋松手柄固定鈕,將電源線嵌入手柄夾頭槽內(nèi)
(圖二1)。c. 將手柄穿入夾頭槽底圓孔中(圖二2)
d. 旋緊手柄固定鈕夾緊手柄,并使主機基本保持水平(圖二3)e. 拆除指針主桿上的橡皮圈和主機下端的黃色包裝套圈(圖三)。
警告!在未拆除上述兩項前不可通電開機,否則將損壞機器。
f. 接上電源,調(diào)整水平調(diào)整腳(圖四),使水準(zhǔn)器中水平泡居于中心圓圈中(圖五)。
Installation:
1) Take out the support stand, column from the packing box.
2) Screw the column into the hole at the rear of the support stand with the teethed side facing the front of the support stand. Tighten the 3 adjustments underneath the stand support.
3) Installation of Main Body:
a. Take out of the main body and loose the screw.
b. Loose the fixed button and embed the power cord into the groove of the clamp.
c. Let the handle get through the hole of groove of the clamp.
d. Tighten the fixing screw on lever and keep the main body horizontal.
e. Remove the rubber band on the indicator control lever, release the yellow screw at the lower end of the instrument and lastly remove the yellow packing ring.
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(zhǔn)備被測液體,選擇直徑>or=70mm 的圓柱型容器。
3) 按測量要求的,準(zhǔn)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(zhuǎn)子號,并將轉(zhuǎn)子左旋入連接螺桿(圖4).然后旋轉(zhuǎn)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(zhuǎn)子液面標(biāo)志和液面平為止。(圖4)按下指針鎖定桿,開啟電源開關(guān),放開指針鎖定桿,使轉(zhuǎn)子在液體中旋轉(zhuǎn),一般20~30秒的運轉(zhuǎn),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(guān)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(dāng)電機關(guān)停后,如指針不處于讀書窗內(nèi),應(yīng)繼續(xù)按住指針鎖定桿,反復(fù)開啟和關(guān)閉電機,使指針處于讀數(shù)窗內(nèi)。
