Prior to connecting the DC input source, set the
current limit of the input supply to 0.1A maximum. Make sure the input source is initially
set to 0V and connected to the VIN+ and VIN– connection points as shown in Figure 2-1. TI recommends an additional input bulk capacitor to provide damping when using long
input lines.
Connect voltmeter 1 at the VIN+ and VIN– sense
points to measure the input voltage.
Connect ammeter 1 to measure the input current
and set to at least 1-second aperture time.
