Follow these instructions before starting any test and repeat again before moving to the next test:

  • Set the power supply output (VIN) to zero volts.
  • Turn off the power supply.
  • Adjust the jumper positions on EVM to the default configuration as shown in Table 5-1.
  • Turn the power supply on and set the power supply output (VIN) to 12 V, 200 A, and keep the power supply output disabled.

  • Enable the power supply output so that the EVM gets the input power supply.
