２．２ 放大電路
放(fang)大(da)電(dian)路(lu)是(shi)在(zai)主(zhu)板(ban)上(shang)的(de)模(mo)擬(ni)電(dian)路(lu)，主(zhu)要(yao)用(yong)來(lai)增(zeng)益(yi)電(dian)位(wei)水(shui)平(ping)低(di)的(de)力(li)矩(ju)或(huo)重(zhong)量(liang)信(xin)號(hao)。常(chang)見(jian)故(gu)障(zhang)也(ye)是(shi)顯(xian)示(shi)不(bu)正(zheng)常(chang)或(huo)無(wu)顯(xian)示(shi)，在(zai)排(pai)除(chu)傳(chuan)感(gan)器(qi)故(gu)障(zhang)的(de)可(ke)能(neng)性(xing)後(hou)，即(ji)可(ke)檢(jian)查(zha)此(ci)部(bu)分(fen)。現(xian)在(zai)常(chang)用(yong)的(de)力(li)矩(ju)限(xian)製(zhi)器(qi)放(fang)大(da)電(dian)路(lu)大(da)多(duo)采(cai)用(yong)集(ji)成(cheng)電(dian)路(lu)，因(yin)此(ci)可(ke)以(yi)用(yong)替(ti)代(dai)法(fa)來(lai)進(jin)行(xing)檢(jian)查(zha)。
在放大電路中有兩個調整點，一個是零位調整（ZERO ADJUST），一個是放大倍數調整（SPAN ADJUST）。有些力矩限製器（例如TADANO起重機上常用的AML-M1型力矩限製器）甚shen至zhi直zhi接jie將jiang這zhe兩liang個ge調tiao整zheng點dian引yin出chu來lai，做zuo成cheng旋xuan鈕niu以yi供gong調tiao整zheng，在zai顯xian示shi不bu準zhun確que時shi可ke以yi調tiao整zheng這zhe兩liang個ge旋xuan鈕niu。但dan在zai調tiao整zheng前qian要yao弄nong清qing到dao底di應ying該gai調tiao哪na一yi個ge。以yi起qi重zhong量liang為wei例li，用yong一yi組zu重zhong量liang已yi知zhi的de重zhong物wu為wei砝fa碼ma，逐zhu次ci吊diao起qi，將jiang顯xian示shi值zhi記ji錄lu下xia來lai，比bi較jiao顯xian示shi值zhi與yu真zhen實shi值zhi的de差cha，如ru果guo每mei組zu差cha值zhi不bu變bian，則ze應ying調tiao零ling，如ru每mei組zu差cha值zhi隨sui吊diao重zhong量liang增zeng加jia而er增zeng加jia，則ze應ying調tiao整zheng放fang大da倍bei數shu。
２．３ 執行機構
執(zhi)行(xing)機(ji)構(gou)通(tong)常(chang)是(shi)電(dian)磁(ci)閥(fa)。其(qi)故(gu)障(zhang)現(xian)象(xiang)是(shi)顯(xian)示(shi)一(yi)切(qie)正(zheng)常(chang)，力(li)矩(ju)限(xian)製(zhi)器(qi)也(ye)報(bao)警(jing)，但(dan)應(ying)該(gai)自(zi)動(dong)停(ting)止(zhi)的(de)操(cao)作(zuo)依(yi)然(ran)能(neng)夠(gou)操(cao)作(zuo)。這(zhe)時(shi)可(ke)以(yi)檢(jian)查(zha)相(xiang)應(ying)的(de)電(dian)磁(ci)閥(fa)線(xian)圈(quan)是(shi)否(fou)正(zheng)常(chang)，以(yi)及(ji)在(zai)起(qi)重(zhong)機(ji)處(chu)於(yu)應(ying)該(gai)停(ting)止(zhi)狀(zhuang)態(tai)時(shi)是(shi)否(fou)有(you)電(dian)信(xin)號(hao)到(dao)該(gai)電(dian)磁(ci)閥(fa)。
