我個千瓦時計下面有5個孔,,
中間果個零零捨捨吾同,,
估計果個係E,,
左2個,,右2個我諗係Input既L,N同Output既L,N,,
就係li 4個孔吾識分!!
5個孔除左中間果個之外,,
由左至右分別當係1,,2,,3,,4,,
1,,2有0Ohm,,
3,,4有0Ohm,,
1,,3有721Ohm,,
2,,4有721Ohm,,
應該1,2吾係Input既線;3,4吾係Output既線 la!
全通咪short circuit!!
請高手教教小弟!
佢話係單相瓦時計! 寫住10(20A),, 是10A?!還是20A,,還是10x20A = 200A?!?!?! 600revs/kWh,, 咁佢咪轉得好slow?!
佢冇標明咩孔打咩孔,, 冇寫L,N,E,Output,,Input,, 如有我吾使咁頭痕!
佢係2手,, 有人用過! 未調零,, 我想調零再計過! 有咩位可以比我調零?!
而1配3和2配4 係有0.9K Ohm!
1配,3,4同2配,3,4有863 Ohms

2做輸入1做輸出?! But 2 And 1 No Resistance,, It Will Short Circuit!

http://xs.to/xs.php?h=xs140&d=09250&f=__22294___20687_086658.jpg 我駁好左! 吾知啱吾啱! 吾敢開電,, 幫我睇1睇
但L和N始終有721Ohms,, 我驚Short Circuit!
我照你方法駁,,但個Meter吾轉!
個meter震震下,, 用電時個meter既轉盤吾轉!

The Foil Is Not Will But The AC Circuit Is Correct, The Electrical Appliances Still Can Be Used,, It Prove That The Wiring Not Incorrect, The Problem Is In The Meter?!
