用定值电阻点检法作者: milighost 时间: 2011-12-29 17:02
运行检查也叫期间核查，是指的在校准周期内定期设置的故障条件，判别功能是否正常。 ) {3 _7 t" s( m2 \, A3 F4 X+ E( u9 s! H对于耐压测试仪其实可以比较简单，只要在设定的电压下将表笔短接看是否报警就可以了。作者: yxd2008 时间: 2011-12-29 18:19

Prior to the test, the sensitivity of the dielectric tester - which indicates breakdown - was adjusted to indicate a breakdown when the tester was connected to a 120,000-ohm load. The applied voltage was started at zero, increased to the final value, and held at that value for the one minute.作者: songbolove 时间: 2011-12-29 21:14

表笔直接短接没现在不认可了，要用电阻法治具点检作者: novice-safty 时间: 2012-2-28 12:36
3C审厂和KTL审厂都要求的是用电阻法作者: douwang 时间: 2012-4-9 14:36
问一下第三方校准机构就行了作者: abu013 时间: 2012-4-10 10:52
我看电阻法可行.作者: mikk 时间: 2012-4-14 14:50
和校准的时候一样的··一个是输出的电压看偏差是否偏离了要求值，其次就是用标准的定值电阻看击穿电流是否准确·····JJG 759-2004
