Hi All, Just want some guidance so I have one AIM-4 channel module that is getting 11.23 ma and instead of giving me 43% reading it is giving me 57% any idea Why?
I already change the module and same thing
I’m using pac-manager to check my ma
by the way I have some other module with more ma let’s say 11.57 and they are reading 48%
any help will be appreciated…thank you

Please take a screen shot like this of your module and point;

It will be helpful for us to see the scaling and how the point is configured.
(Note, your module will of course be different to this screenshot).
