AB羅克韋爾1746-RL54模塊
使用前，首先要做好以下各種準(zhǔn)備：測量前必須將被測設(shè)備電源切斷，并對地短路放電，決不允許設(shè)備帶電進(jìn)行測量，以保證人身和設(shè)備的安全。對可能感應(yīng)出高壓電的設(shè)備，必須消除這種可能性后，才能進(jìn)行測量。被測物表面要清潔，減少接觸電阻，確保測量結(jié)果的正確性。測量前要檢查兆歐表是否處于正常工作狀態(tài)，主要檢查其“0”和“∞”兩點(diǎn)。即搖動(dòng)手柄，使電機(jī)達(dá)到額定轉(zhuǎn)速，兆歐表在短路時(shí)應(yīng)指在“0”位置，開路時(shí)應(yīng)指在“∞”位置。
其中，L表示明度的差異，當(dāng)L為正時(shí)表明其較樣品而言偏白，當(dāng)L為負(fù)時(shí)，表明其較樣品而言較黑;a表示色調(diào)的差異，當(dāng)a為正時(shí)表明其偏紅，當(dāng)a為負(fù)時(shí)表明其偏綠;b表示彩度的差異，當(dāng)b為正時(shí)表明其偏黃，當(dāng)b為負(fù)時(shí)表明其偏藍(lán)。色差儀根據(jù)外觀形狀，有手持式、便攜式、臺式之分;種類主要是三刺激值色差儀和分光光度計(jì)色差儀兩類。三刺激值色差儀就是我們通常所說的色差計(jì)，只模擬人眼測試物體的紅、綠、藍(lán)三刺激數(shù)據(jù)，價(jià)格便宜，體積小，便于攜帶。

PLC
處理器(CPU)由控制器、運(yùn)算器和寄存器組成并集成在一個(gè)芯片內(nèi)。CPU通過數(shù)據(jù)總線總線、地址總線、控制總線和電源總線與存儲器、輸入輸出接口、編程器和電源相連接。
小型PLC的CPU采用8位或16位微處理器或單片機(jī)，如8031、M68000等，這類芯片價(jià)格很低；中型PLC的CPU采用16位或32位微處理器或單片機(jī)，如8086、96系列單片機(jī)等，這類芯片主要特點(diǎn)是集成度高、運(yùn)算速度快且可靠性高；而大型PLC則需采用高速位片式微處理器。
CPU按照PLC內(nèi)系統(tǒng)程序賦予的功能指揮PLC控制系統(tǒng)完成各項(xiàng)工作任務(wù)
