溶(rong)(rong)(rong)(rong)出(chu)(chu)杯(bei)(bei)(bei)(bei)與攪拌槳(jiang)（籃(lan)）一(yi)樣有不同的(de)編號(hao)。使(shi)用時也應將(jiang)溶(rong)(rong)(rong)(rong)出(chu)(chu)杯(bei)(bei)(bei)(bei)安(an)裝到對應的(de)位置(zhi)。除了(le)溶(rong)(rong)(rong)(rong)出(chu)(chu)杯(bei)(bei)(bei)(bei)的(de)編號(hao)要對應外，溶(rong)(rong)(rong)(rong)出(chu)(chu)儀通過了(le)垂直度與同軸度驗證后，溶(rong)(rong)(rong)(rong)出(chu)(chu)杯(bei)(bei)(bei)(bei)上緣與固定裝置(zhi)相連的(de)位置(zhi)上都做好標記。如：豎線、箭頭。 因此(ci)，在(zai)(zai)進行溶(rong)(rong)(rong)(rong)出(chu)(chu)度試(shi)驗時，應將(jiang)各籃(lan)軸、槳(jiang)和溶(rong)(rong)(rong)(rong)出(chu)(chu)杯(bei)(bei)(bei)(bei)放在(zai)(zai)原已通過驗證的(de)位置(zhi)上，保(bao)持各溶(rong)(rong)(rong)(rong)出(chu)(chu)杯(bei)(bei)(bei)(bei)與固定裝置(zhi)的(de)相對位置(zhi)不變。但(dan)是大家在(zai)(zai)安(an)裝溶(rong)(rong)(rong)(rong)出(chu)(chu)儀時往(wang)往(wang)會忽略這點，使(shi)的(de)溶(rong)(rong)(rong)(rong)出(chu)(chu)杯(bei)(bei)(bei)(bei)的(de)軸度與攪拌槳(jiang)的(de)軸度不重合，通用型8杯(bei)(bei)(bei)(bei)溶(rong)(rong)(rong)(rong)出(chu)(chu)儀哪家好，進而(er)改變溶(rong)(rong)(rong)(rong)出(chu)(chu)杯(bei)(bei)(bei)(bei)內溶(rong)(rong)(rong)(rong)出(chu)(chu)介(jie)質的(de)流動狀態，使(shi)溶(rong)(rong)(rong)(rong)出(chu)(chu)數(shu)據發生變化。

在溶出杯的水平(ping)面板上(shang)從兩個垂直(zhi)方向(xiang)上(shang)測(ce)量，兩次測(ce)量的數值均不(bu)得超出0.5°。

　將需(xu)驗證的溶(rong)出(chu)(chu)(chu)儀(yi)(yi)(yi)放置在一水平且平穩工(gong)(gong)作(zuo)臺(tai)上(shang)，工(gong)(gong)作(zuo)臺(tai)所處環境不(bu)(bu)允許有振動(dong)。調節(jie)溶(rong)出(chu)(chu)(chu)儀(yi)(yi)(yi)底(di)腳，使溶(rong)出(chu)(chu)(chu)儀(yi)(yi)(yi)杯板在前(qian)后、左右兩個方向上(shang)均能(neng)(neng)接近水平。在后續的驗證及驗證后的試驗過程中不(bu)(bu)能(neng)(neng)調整(zheng)或移動(dong)溶(rong)出(chu)(chu)(chu)儀(yi)(yi)(yi)，否則需(xu)要對溶(rong)出(chu)(chu)(chu)儀(yi)(yi)(yi)進行重新(xin)驗證。技術要求：緊貼(tie)籃(lan)（槳）軸(zhou)(zhou)(zhou)測量(liang)(liang)(liang)垂(chui)直度，再(zai)沿籃(lan)（槳）軸(zhou)(zhou)(zhou)旋轉(zhuan)90°測量(liang)(liang)(liang)，每根籃(lan)（槳）軸(zhou)(zhou)(zhou)兩次(ci)測量(liang)(liang)(liang)的數值均不(bu)(bu)得超(chao)出(chu)(chu)(chu)90.0°±0.5°。
