Experimental gain and offset of the IA: First, we set up the IA on our protoboard using A 1 kΩ resistor and connected it to the computer through the BNC accessory box, where we ran “pressure daqmx with state machine.vi” (provided) to test the gain and offset of the chip. We made a new DAQmx task to compare the input and output voltages, and saved this data in an excel file where we created a graph to visualize the relationship. We had to do this part twice, because after the first run we realized that the chip was wired incorrectly. The corrected results are: Input voltage or
