NI9215 Single ended connection

[william879]

Dear All,

I am using NI 9215 to collect 3 voltage singles simultanousely. I know I suppose to connect the AI- to the COM terminal. However, when I do so, the signal seems to be wrong. When I just connect AI+ and AI- (sharing the same reference by connect all AI- together), the signals are good.

I am worry that it may cause damage if I don't follow the instruction. Please advice.

Jake
