在电感比较仪或其它使用电感测量头的仪器中,让电感测量头处于自由状态(即最负状态),然后缓慢抬高电感测头的测量端,这时电感比较仪的表头刻度上会有一个从负经零到正的全过程。但是也确有个别的电感比较仪会出现2个或2个以上的零点指示,这就是所谓的“多零点”。零基准只应有一个,多的零基准我们称之为伪基准。 In the inductive comparator or other inductive measuring head instrument, let the inductive measuring head in a free state (ie, the most negative state), and then slowly raise the measuring head of the inductive probe, inductive comparator meter scale will be There is a whole process from negative to positive. However, it is true that there are two or more zero indications for individual inductive comparators. This is called “multiple zeroes”. There should be only one zero reference, more than zero reference we call pseudo-benchmark.
