4.3.1 Input Connections

  • Connect voltmeter1 at VINS+ and VINS– .
  • Connect ammeter1 to VIN+.
  • Prior to connecting the power supply, set the current limit of the power supply to 0.3-A maximum and ensure the initial output voltage is set to 0 V. Connect to the VIN- and the ammeter1 as shown in Figure 4-1.
