Hello Experts,
I bought NI usb 6225 and was happy with the 80 AI channels. But I didn't notice it hasn't an internal excitation as normal meters. Now since my arrangement is based on 24 RTD temperature sensors that will be employed in a feedback control loop.... Do you have any good idea to develop the exciation current in the 24 resistances using for example the 4 AO channels or what kind of external excitation is needed??? Please answer ASAP!
Thanks!
