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. Power on the instrument
Press the Power key on the front panel to power on the instrument.
2. Connect the DUT and the channel input terminals of the load
Connect the DUT and the channel input terminals on the front panel of the load
as shown in Figure 2-2.
CAUTION
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.
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.
