LFS660產(chǎn)品描述LFS660 Product Description
LFS660測(cè)試儀可以檢驗(yàn)操作員手腕帶和防靜電鞋的功能，并判斷這種功能是否可以充當(dāng)接地線路，確�？梢宰鳛榈孛嬖O(shè)備的限流電阻。操作員手腕帶和防靜電鞋測(cè)試可以同時(shí)進(jìn)行，無(wú)需分開(kāi)測(cè)試。綠燈亮，說(shuō)明測(cè)試通過(guò)。紅/藍(lán)燈亮并伴有警鳴聲，說(shuō)明測(cè)試失敗。可能手腕帶和防靜電鞋都沒(méi)通過(guò)，可能是其中一項(xiàng)沒(méi)有通過(guò)。如果是防靜電鞋沒(méi)有通過(guò)，可能是其中一只沒(méi)有通過(guò)，左腳或者右腳。如果測(cè)試失敗，測(cè)試儀會(huì)顯示地面設(shè)備的電阻，看是電阻值太低還是太高。
The LFS660 tester verifies the functionality of an operator's wrist strap and footwear.It determinesif an operator’s wrist strap and footwear will act as a path-to-ground and ensures the presence of a current-limiting resistor in the grounding devices.The operator’s wrist strap and footwear will test simultaneously without separate testings.Green lights indicate that the wrist strap and footwear are passing. Blue or red lights and an audible alarm indicatewhen the wrist strap and/or footwear (left or right) are failing.If failure occurs,the tester will also display if the grounding device’s resistance is too low or too hig |
