4.3.4.1 Preparation

Double check to make sure the DC power supply is fine, and click the Supply is Connected button in the Hardware Setup page. And then click the Start Checks button to start the hardware check. Once completing the hardware check correctly, PPC3 needs to show the check results as in Figure 4-6.

Next, in the System Gain Calibration page, click the Start Gain Calibration button to start the system gain calibration process. Use the DC mode of the multimeter to measure the supply DC voltage over PVDD and GND, and use the AC mode of the multimeter to measure the output AC voltage (RMS) across the L+ and L- pins of the learning board.

Type the measurement results into the corresponding boxes in the System Gain Calibration page, and click the Next button to enter the next step.
