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 3-1.
Connect
voltmeter 1 at VIN+ and VIN– connection points to
measure the input voltage.
Connect
ammeter 1 to measure the input current and set to
at least 1-second aperture time.
