1.7 CV/CC Crossover Characteristics
Background
The instrument automatically switches between constant voltage mode (CV) and constant current
mode (CC), according to load condition.
CV mode
When the current level is smaller than the output setting, the instrument operates in Constant
Voltage mode. The indicator on the front panel turns green (C.V.) The Voltage level is kept at the
setting and the Current level fluctuates according to the load condition until it reaches the output
current setting.
CC mode
When the current level reaches the output setting, the instrument starts operating in Constant Current
mode. The indicator on the front panel turns red (C.C.) The Current level is kept at the setting but
the Voltage level becomes lower than the setting, in order to suppress the output power level from
overload. When the current level becomes lower than the setting, the instrument goes back to the
Constant Voltage mode.
