2.1.3.2 Output Connections

  • Connect an electronic load to VOUT+ and VOUT– connections as shown in Figure 2-1. Set the load to constant-resistance mode or constant-current mode at 0A before applying input voltage.
  • Connect voltmeter 2 at VOUT+ (TP5) and VOUT– (TP6) sense points to measure the output voltage.
  • Connect ammeter 2 to measure the output current.
