You can test the board using the Test Panels in National Instruments Measurement and Automation (MAX).
- Open MAX. In the configuration tree, select your A/D card (under NI-DAQmx devices). Click the “Test Panels…” button.
- On the Analog Input tab, set the channel name to DevX/ai0, set the mode to On Demand, set the input configuration to RSE, and uncheck Auto-scale chart. Connect an EMG sensor to channel 1 on the amplifier and set the gain knob to 1k.
- Press Start. At this point you should see the data responding if you tap one of the silver bars with your finger. The signal should be flat when the bars are shorted.
