Hello, I have notice that there is a voltage of 1V coming out of each TTL input channels and I do not know how to turn it off. I tried the .off() function but couldn't get it turned off. Can I ask if there is a way to set it to zero voltage ?
Put a load resistor to ground?
We did that, but we don't know if the current we measured is at normal value, so we thought it might be different for some settings. Can I confirm that 1V is the normal output voltage you get and current ~ 140uA?
There are no settings that affect leakage current on inputs. Using the output control functions while the card is in input mode has no effect.
What exactly did you connect (please describe the entire circuit precisely) and how are you taking those measurements?
