This chapter describes the functions and features of the power system in Load
mode. Divided into the following sections:
♦ Programming the Input
♦ Advanced Feature

5.1 Programming the Input
5.1.1 Select the Operation Mode (Mode)
When the [Load] key is pressed on the front panel, the instrument is switched
to Load. There are eight modes of operation, which can de divided to basic op-
eration modes and complex operation modes according to function types.
• Basic operation modes: CC (constant current), CV (constant voltage), CW
(constant power), CR (constant resistance);
• Complex operation modes: CVCC (CV+CC), CVCR (CV+CR), CRCC (CC
+CR), AUTO (CV+CC+CW+CR).
After the desired operation mode is selected in the Config menu, the corre-
sponding key light will be lit. At this time, the setting value in the corresponding
mode can be set. If other keys are pressed, the front panel will prompt “Opera-
tion Mistake”. For example, when the load is in CVCC complex mode, the
[V-set] and [I-set] key lights are lit. You can set the input voltage value and cur-
rent value of the load. But [P-set] and [R-set] keys are not available in this
mode.
The procedures to select the operation mode are as follows.
1. Press [Shift]+[V-set] (Config) to enter into the configuration menu interface.
The first displayed menu item Beep is to select the operation mode.
2. Press [Enter] key to enter into the parameter setting interface.
3. Press the Left / Right key or turn the knob to adjust the value of this
parameter.
4. After the parameter settings are complete, press [Enter].
