ET5406A+/ET5407A+ Programmable DC Electronic Load - User Manual
These four modes are considered the basic operation modes. After the channel is activated, all
parameters other than the turn-off delay time can be edited and take immediate effect.
3.1. Constant Current (CC)
In CC mode, the electronic load consumes a constant current, regardless of input voltage
changes.
3.1.1. Main Display Interface
As shown in Fig. 3-1-1-1, the Main Display Interface displays the measured voltage n the
first line, the measured current on the second line, and power on the third line. The "CC" on the
top right indicates the CC mode.
3.1.2. Parameter Editing
Press the [ENT] button on the Main Display Interface to enter Parameter Editing interface.
Use the arrow buttons [▲ ▼◄ ►] or knob to select the parameter to be edited.
Press the [ENT] button to edit the selected parameter and use the arrow buttons [▲ ▼◄ ►]

Current Setting: Constant current to be consumed in CC mode.
Turn-off Delay Value: After the channel is activated, a countdown begins, and the channel
will be deactivated when the countdown reaches zero.
Current, Voltage and Power Limits: They are typically set to their maximum values. If
