3.5.1 Procedure
1. Working at an ESD workstation, make sure that any wrist straps, bootstraps or mats are
connected referencing the user to earth ground before power is applied to the EVM. Electrostatic
smock and safety glasses should also be worn.
2. Prior to connecting the DC input source, V
12V_IN
, it is advisable to limit the source current from
V
12V_IN
to 5.0A maximum. Make sure V
12V_IN
is initially set to 0V and connected as shown in
Figure 2.
3. Connect the ammeter A1 (0-5A range) between V
12V_IN
and J1as shown in Figure 2.
4. Connect voltmeter V1 to TP6 and TP7 as shown in Figure 2.
5. Connect LOAD1 to J2 as shown in Figure 2. Set LOAD1 to constant current mode to sink 0Adc
before V
12V_IN
is applied.
6. Connect voltmeter, V2 across TP8 and TP11 as shown in Figure 2.
7. Connect Oscilloscope probe to TP9 and TP10 as shown in Figure 3.
8. Place Fan as shown in Figure 2 and turn on, making sure air is flowing across the EVM.
