Hi Hamza, yes i was able to do what i needed by using the Current sense pin.

[see the attached picture.]

I send 3V3 by CH.43, i use channel 21-40 only as switches.
And 1-20 as readings with ground as common.
In my Python code i :
- click ch.21
- loop read 1 to 8, and make sure only 1 has voltage.
- do that for all channels.

Need pull-down resistors or you have floating-residual-capacitive-voltage-stuff readings.

Alright?

Hi,

I really hope someone can help me with that.

I want to test continuity in 4 wires (which is easily done)
All 4 channels resistance tests will return  < 1 ohm. if all ok.

And then detect possible shortcut fails between those 4 wires : (attached picture 1)

Like for example, checking between 13-H to 14-H, 13-H to 15-H, etc.
In fact, if im not wrong, to check any possible shortcuts, i need to make sure i get infinite ohms between all combinations.

Is it possible with this card ?? : (attached picture 2)


Thank you so much.
