4.3.4 Plots Tab

The Plots tab contains a plot window that shows the progression of data over time on the INA233. All four variables at the bottom of the EVM software (Vshunt (READ_VSHUNT_OUT), Vbus (READ_VIN), Current (READ_IIN) and Power (READ_PIN)) can be plotted using the drop-down box directly below the graph. After the desired plot has been selected, toggle the Capture Data in Loop button above the plot to begin polling for data.
