Hello ,
I am working on a Relay-test program the hardware is composed from the Keithley to take the mesearment and a Pickering card to match all the pins with the Realy matrix .
My problem is when the keithley is on , i get the error message "Overflow MΩ" and the program cant find the pickering card .
When the Keithley is off the program can find the Pickering card but of course i can t take the meserments from the Matrix .
I started to debug the prorgamm and i have noticed that i have different values in both situations . As a beginner i couldnt find the reson of this conflict .
i screen shoted where i have found different values
any help is welcome!
Thanks
