Ranges
You can select the lower or higher range for CW mode too. Power can be
edited in either of the two ranges. Low range will supply higher accuracy and
better resolution when you set lower power. Any value you set is outside the
maximum value of the LOW RANGE, you should select HIGH RANGE.
Immediate power level
You could set the power level via front panel. If the load is in CW mode, the new
setting power level immediately changes the input at a rate determined by the
slew rate. If the load is not in CW mode, the setting power level will be saved for
use until switch to CR mode.
Limited current value
Set limited current value under CW mode.
Transient power level
Set A/B transient power level on front panel or by remote operation, the load
can continuously toggle between the two levels when transient operation is
turned on.
4.3.5 Compound Operation Mode
IT8700P series electronic load has four compound operation modes: CV+CC,
CV+CR(CR-LED), CR+CC and CW+CC. These four compound operation
modes add A-Limit ( limited current value) setting function under CV/CR/CW
mode, which can help engineers solve the transient surge current problems,
avoid to trigger the protection function and protect DUT from burning.
⚫ The CV+CC mode can be applied to the load simulation battery and test
the charging station or the car charger. When the CV is working, the
maximum loading current is limited.
⚫ The CR+CC mode is commonly used in the testing of voltage limiting,
current limiting characteristics, constant voltage accuracy, and constant
