1. Prior to connecting the DC input source V
IN
, it is advisable to limit the source current from V
IN
to 10 A
maximum. Make sure V
IN
is initially set to 0 V and connected as shown in Figure 7-2 .
2. Connect a voltmeter V1 at TP1(V
IN
) and TP2 (GND) to measure the input voltage.
7.2.2 Output Connections
1. Connect Load to J2 and set Load to constant resistance mode to sink 0 A
DC
before V
IN
is applied.
2. Connect a voltmeter V2 at TP6 (V
OUT
) and TP8 (GND) to measure the output voltage.
7.2.3 Other Connections
Place a fan as shown in Figure 7-2 and turn it on, making sure air is flowing across the EVM.
