I just don't get it! I've got Labview 8.5, NI-DAQmx 8.6. I just purchased the NI USB-6212 portable daq board and I'm new with SignalExpress LE. I cannot get the USB device to read the voltages that are pressent on its terminals. My system is a simple strain gauge pressure transducer (full bridge), a signal conditioner (Newport iDRN) and a 12 volt power supply. I measured my low pressure voltage at -0.155v and my high pressure at 11.69 v. I have scaled this voltage range to be 0 - 200 psig in SignalExpress; however, I either get '0' psig, or, '21' psig! I have tried five (5) transducers. All other equipment, including the USB-6212 is brand new!
