磁(ci)體排除平衡裝置（FCS Field Cancelling Systems）
FCS交變電(dian)場避免設施都可以挺高對交變電(dian)場刺激性(xing)(xing)的(de)自動化儀器設備的(de)穩(wen)定性(xing)(xing)，如(ru)掃(sao)描軟件電(dian)鏡，散(san)發出電(dian)鏡和圖形濾(lv)出器。
標準(zhun)的FSC其中包括(kuo)，電(dian)(dian)(dian)(dian)(dian)(dian)交變電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)調(diao)控設施，電(dian)(dian)(dian)(dian)(dian)(dian)交變電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)調(diao)節器器和三(san)（X、Y&Z）電(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)纜回(hui)路開關。FCS工做(zuo)機制是生(sheng)成(cheng)和波動(dong)，象限，趨(qu)勢(shi)相反(fan)的詞語(yu)的電(dian)(dian)(dian)(dian)(dian)(dian)交變電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)抵銷(xiao)四周(zhou)電(dian)(dian)(dian)(dian)(dian)(dian)交變電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。
FCS 22運(yun)作工作頻率在0.5Hz到5000Hz，是可以(yi)沖減而(er)言磁體(ti)源的(de)打擾(rao)，如磁感應(ying)體(ti)和(he)機戒轉動(dong)或者(zhe)單(dan)方向轉動(dong)磁體(ti)。
FCS 20W還可以(yi)在DC到(dao)5000Hz的頻率時(shi)間范(fan)圍內很好的縮減人體磁場。
不但互減弱電壓聲音(yin)頻率的(de)電場(chang)(chang)，FCS 20W也是可(ke)以夠互減弱合金產品工(gong)件中移動帶來的(de)底(di)頻電場(chang)(chang)，如住(zhu)宅電梯和客車緊挨玄幻ed2k系統的(de)會帶來很高等(deng)教育級的(de)DC電場(chang)(chang)。
能選項：
比(bi)如(ru)扣(kou)減調節器器，支持系統對有諸多人體磁(ci)場(chang)強(qiang)度(du)敏感(gan)脆弱檢測儀器一些裝用GATAN專業能力過(guo)濾(lv)系統器的TEM的臥室(shi)補償金轉(zhuan)變人體磁(ci)場(chang)強(qiang)度(du)和(he)Helmholtz電子線束(shu)。
