2.2.1.1 Detailed Setup

To configure a measurement evaluation, follow these steps:
  1. With the load powered off, connect the IN+ and IN– terminals in series with the load, as shown in Figure 2-3. Make sure the current does not exceed 15A. If desired, the current can be split across the two terminals for IN+ or IN–. Alternatively, the additional input pins can be used to connect to the VBUS terminal.

    WARNING:

    When measuring current, first make sure that the equipment (wires, connectors, and so on) can support the amperage and power dissipation. Secondly, make sure that the current flowing through J1 does not exceed 15 A. Failure to do so can result in damage to the EVM, or personal injury.

    The EVM can get hot.

  2. Connect the VBUS terminal (J1 pin 2) to the desired bus voltage (likely either IN+ or IN–).
    1. If VBUS and dependent features are not being used, then this channel can be used as an ADC input for another voltage.
  3. Connect the system ground to the GND terminal (J1 pin 1).
  4. Power on the system, and observe the device states and outputs through the GUI.
