5-8. CP + CV mode of operation application

Operating in CP + CV mode, 34000A series at the same time as a Constant Power and
Constant Voltage Load, as shown in Fig 5-9.
When Operating at Constant Power (CP) load, 34000A series electronic load provides specified
power, independent Constant Voltage source (VM) is output voltage.
When Operating at Constant Voltage Load on, the VM is greater than V, Input power changes
its input voltage is keep fixed.
When the VM voltage is less than equal to the set voltage CV, the load does not sink current.
Operation Way:
• Load input terminals are connected to the DUT
• Change to CP mode and setting CP power setting.
• Press Limit key to setting the CV voltage and the display will show "Add.CV".
• Press START key to start up the CP+CV test, and press "STOP "key to stop CP+CV test.
