Connect the IN+ and IN– terminals in series with the load while powered off.
When measuring more than 10 A, make sure the high current path does not go through the EVM (including the terminal block J1), as shown in Figure 4-14.
Figure 4-14 IN+ and IN– Wiring for More Than 10A
When using 10 A or less with either an onboard or external shunt, the current path can be passed through the EVM. Figure 4-15 shows a convenient way to use the multiple IN+ and IN- terminals with an external shunt for this use case.

WARNING:
When measuring current, first make sure that the equipment (shunt resistor, wires, connectors, and so on) can support the amperage and power dissipation. Secondly, make sure that the current flowing through J1 does not exceed 10 A. Failure to do so can result in damage to the EVM, or personal injury.
The EVM may get hot.
Connect the VBUS terminal (J1 pin 2) to the desired bus voltage (likely either IN+ or IN–).
If VBUS and dependent features are not being used, this channel can be used as an ADC input for another voltage.
Connect the system ground to the GND terminal (J1 pin 1).
Power on the system, and observe the device states and outputs through the GUI.
