question 2: the voltage drop in a protective bonding conductor is measured after conducting the test current for the time period specified below. the test current can be either a.c. or d.c. and the test voltage shall not exceed 12V.8 U# `( P& o5 H3 [8 H6 e7 f
这个VOLTAGE DROP就是用万用表还是示波器放在Protective bongding conductive 两端测试吗?
