Cc + Cv Mode Of Operation Application; Fig 5-8 Cc+Cv Mode Operation Application - Prodigit 34000A Series Operation Manual

Note: To use CP mode to do battery discharge test when CPRSP = 0(definition is 0),
the ... Too long wire may cause oscillation and stop the test. the solution as below.
1. Use Vsense function Connect Vsense for voltage drop compensation (please
refer to section 5-2 for instructions)
2. Use CPRSP = 1~4 to slower the CP mode respose speed, the CPRSP setting in
the Config key.
Note: CPRSP settings will not be stored when turned off, When the 34XXXA power
Is turned on, the CPRSP gear position must be set.

5-7. CC + CV mode of operation application

Operating in CC + CV mode, 34000A series at the same time as a Constant Current and
Constant Voltage Load, as shown in Fig 5-8.
When Operating at Constant Current (CC) load, 34000A series electronic load to Voltage
source (VM) Constant Current load (I) and keep Constant Voltage.
When Operating at Constant Voltage Load on, the VM is greater than V, Input current 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 CC mode and setting CC current setting.
• Press Limit key to setting the CV voltage and the display will show "Add.CV".
• Press START key to start up the CC+CV test, and press "STOP "key to stop CC+CV
Test.
