Specifying the Load Operating Mode
The operating modes of operation for Keysight EL30000 Series electronic load are:
–
Constant current (CC): In this mode, the electronic load will sink a current in accordance with the pro-
grammed value regardless of the input voltage. Note that a programmable voltage limit is not available. If the
DUT imposes a voltage above the voltage rating of the module, the overvoltage protection will trip.
–
Constant voltage (CV): In this mode, the electronic load will sink enough current to control the DUT voltage to
the programmed value. The load acts as a shunt voltage regulator when operating in voltage priority mode.
–
Constant resistance (CR): In this mode, the electronic load will sink a current linearly proportional to the
voltage in accordance with the programmed resistance value.
–
Constant power (CP): In this mode, the electronic load will maintain the input power at the specified pro-
grammed power level.
When programmed to a mode, the electronic load remains in that mode until the mode is changed or until a fault
condition, such as an overpower or overtemperature, occurs.
Refer to the Load Operating Modes for more information.
1. Press Mode or press Load Settings > Mode.
2. Press CC, CV, CR, or CP to select the desired operation mode.
3. Press Back to exit.
Alternatively, you may also set the operating mode under Load Settings > Mode.
