If the input status is OFF, the upper right corner of the display panel will display "OFF". To change the input
status bit to ON, press the On / Off button. The upper right corner of the display panel displays "CV_S" or "Unreg"
"Indicates that the voltage reaches the expected value," Unreg "means the load can not be correctly adjusted to the
preset voltage, please check the source is connected correctly and turned on, the voltage is within the normal range,
or the source can be measured output maximum Whether the current exceeds the load maximum absorption
current.
In the load unload constant voltage mode, press Shift + 2 (S_Start) key, the load will return to the standard
constant voltage mode.
Please note that the set rising edge time will be automatically adjusted to an integer multiple of 20uS.
4.1.4 Constant power operation mode (CP)
In constant power mode, the electronic load consumes a constant power. As shown in the diagram below, if
the input voltage increases, the input current will decrease and the power P (= V * I) will remain at the set power.
Figure 4.9 Constant Power Mode
4.1.4.1 Standard fixed power mode
Press the CP button, the load displays "STANDARD POWR = xxxxxxxxW", prompts the current constant power
value, at this time you can press the number keys and decimal point keys on the panel, enter the desired constant
power value from high to low, and press the Enter key to confirm At this point the load into the standard constant
power mode.
If the input status is OFF, the upper right corner of the display panel will display "OFF". To change the input
status to ON, press the On / Off button. The upper right corner of the display panel displays "CW" or "Unreg"
Indicates that the expected power value has been reached. If "Unreg" indicates that the load can not be adjusted to
the preset power value correctly, check whether the power source is properly connected and turned on, or if the
power supply voltage is too low or the maximum output of the power source under test Is the current insufficient?
If you want to fine-tune the set power value, you can use the upper right corner of the rotary encoder, clockwise
to increase, counterclockwise to adjust to reduce, please note that if the set power value has reached the load set the
maximum power value, Adjust the power value. At this time, the lower right side of the display panel is for setting
the power value indication. One of the digits has a cursor indicating that the current fine adjustment is a unit of the
current position. If the user wants to change the adjustment fineness, he can press down Rotary encoder, rotary
encoder contains a button, each time the button is pressed, the prompt cursor will move a grid, in order to achieve
fine adjustment adjustment.
4.1.4.2 Load / Unload Constant power mode
The principle of loading and unloading mode, please refer to 3.1.1.2 instructions
In standard constant power mode, press Shift + 1 (V_Level) key to enter load unload constant power mode, the
load display "ONSET VOLT = xxxxxxxxV" prompts the current load voltage, at this time you can press the number
keys and decimal point keys on the panel, Enter the required load voltage value from high to low, and press Enter
