4.3.2 Output Connections

  • Connect voltmeter2 at VOUT1S+ and VOUT1S– sense points to measure the CH1 output voltage.
  • Connect voltmeter3 at VOUT2S+ and VOUT2S– sense points to measure the CH2 output voltage.
  • Connect load1 to the VOUT1+ and VOUT1– connections as shown in Figure 4-1. Set the load to constant-resistance mode or constant-current mode at 0 A before applying input voltage.
  • Connect load2 to the VOUT2+ and VOUT2– connections as shown in Figure 4-1. Set the load to constant-resistance mode or constant-current mode at 0 A before applying input voltage.
