4.1 Constant State Test Modes

There are four types of constant state test mode: constant current (CC), constant voltage
(CV), constant resistance (CR) and constant power (CP). In the initialization interface, the
user can select [Mode] by pressing the soft key at the bottom of the screen, and then press
[CC], [CV], [CR], [CP] to enter the corresponding mode.
The user can also press [More] to select more other modes, see Table 4-1.
Table 4-1 Introduction of Constant State Test Modes
Name
The electronic load always consumes constant current regardless of the
CC Mode
input voltage.
The electronic load changes current consumption to keep the input
CV Mode
voltage as the set value.
The electronic load is equivalent to a resistance; it changes the input
CR Mode
current as the voltage changes.
The electronic load always consumes constant power; it reduces the
CP Mode
current when the voltage rises to remain constant power.
There are many modes under this menu that can be selected by the
More Modes
cursor to meet diverse testing requirements.

Parameters
Status Bar Current Mode, Time, Status and Other Parameters
In constant state test modes, set current/voltage/resistance/power and other parameters
will be displayed on the right side of screen. Input on-load parameters that need to be set
by numeric keyboard or knob. In on-load status, Time, Vpp, Ipp and some other parameters
will be displayed at the bottom of the main screen.

4.1.1 Constant Current Test

In CC mode, the electronic load always consumes constant current regardless of the input
voltage.
