CC+CV Function
The load supports CC+CV function that simulates two stages of charging: The load is
set to be in CC mode and simulates constant current (CC) charging. When the
readback voltage is detected and the detected value reaches the preset voltage, the
load switches to the CV mode to simulate constant voltage (CV) charging. This
function is used to test the charger and similar devices.
Operation Procedures:
1. Connect the DUT and the channel input terminals of the load
Turn off the instrument, as shown in Figure 2-2, connect the DUT and the
channel input terminals on the front panel of the load.
While making a connection, the positive polarity of the load should
be connected to the (+) terminal of the channel output, and the
negative polarity of the load to the (-) terminal of the channel
output. A misconnection with the terminals may cause damage to
the instrument or the DUT.
2. Power on the instrument
After the instrument is connected to the power source, press the Power key
on the front panel to power on the instrument.
3. Set channel parameters
Press Option to enter the advanced function interface, and then use the
Up/Down arrow keys or the knob to switch to "CC+CV". Press OK or OK to
enter the main interface of CC+CV function, as shown in Figure 2-41. "CC+CV"
is displayed at the top of the main interface.
Figure 2-41 Main Interface of CC+CV Mode
In CC+CV mode, you need to set the following parameters: Current, C_Range,
Voltage, V_Range, V_Limit, and C_Limit.
