2.2 Power Supply Connection (Refer to Figure 2−1)
1) Set the dual dc power supply to
±
5 V. If available, set the current limit on
the dc power supply to 100 mA.
2) Make sure the dual dc power supply is turned off before proceeding to the
next step.
3) Connect the positive (+) terminal of the power supply to the positive (+)
terminal of the current meter number 1.
4) Connect the negative (–) terminal of the current meter number 1 to +VS
(J8).
5) Connect the common ground terminal of the power supply to GND (J7).
6) Connect the negative (–) terminal of the power supply to the negative (–)
terminal of the second current meter.
7) Connect the positive (+) terminal of the current meter number 2 to –VS
(J5).
