I have cDAQ voltage output and voltage input modules.
When I try to have a voltage output (from the output module) read by the voltage input module, the input always measures ~0.9V different than the output. (A few examples)
ie: Vout=10V Vin=9.1V
Vout=-10V Vin=-9.1V
Vout=0 Vin=0V
Is there some kind of voltage drop I am missing from the hardware units?
Why don't they read the same and are always offset by ~0.9?
Thanks in advance!
