Prior to connecting the DC input source, set the
current limit of the input supply to 0.1-A
maximum. Ensure the input source is initially set
to 0 V and connected to the VIN+ and VIN–
connection points as shown in Figure 4-1.
Connect voltmeter 1 at VIN S+ and VIN S–
connection points to measure the input
voltage.
Connect ammeter 1 to measure the input current
and set it to at least a 0.1-second aperture
time.
