Hello,

 

I have setup some sets 34972A to measure the resistance, use 4-wire method and with the 34901A multiplexer card.

The normal real resistance is about 8 ~ 200mΩ, but sometimes I will get the negative vaule from 34972A, such as -68mΩ, -150.

I don't know where the negative value come from and don't know the root cause. have you met this problem in your application?

 

Waiting your help......

 

Thanks!

TC
