status bit, press the On / Off button. The upper right corner of the display panel displays "CV" or "Unreg" "Indicates
that the voltage reaches the expected value," Unreg "means that the load can not be correctly adjusted to the
preset voltage, please check the source is connected correctly and turned on, or the source voltage is too low to be
measured, or the output current capacity exceeds the load Maximum load current.
If you want to fine-tune the set voltage value, you can use the rotary encoder in the upper right corner,
clockwise to increase, counterclockwise to reduce, please note that if the set voltage value has reached the
maximum voltage set by the load, Adjust the voltage value. At this time, the lower right side of the display panel is
for setting the voltage value indication. One of the digits under the cursor indicates that the current fine adjustment
fineness is a unit of the current position. If the user wants to change the fine adjustment, 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.
4.1.3.2 load unload constant voltage mode
The principle of loading and unloading mode, please refer to 4.1.1.2 instructions
In the standard constant voltage mode, press Shift + 1 (V_Level) key to enter the load unload constant voltage
mode, then the load display "ONSET VOLT = xxxxxxxxV" prompts the current load voltage, then press the panel
number keys and decimal point Key, enter the required load voltage value from high to low, and press Enter key to
confirm, the load display "OFFSET VOLT = xxxxxxxxV" prompts the current unloading voltage, at this time you can
press the number keys and decimal point keys on the panel, from high to Low enter the desired unloading voltage
value in turn, and press the Enter key to confirm, the load into the load unload resistance mode.
If the input status is OFF, the upper right corner of the display panel will display "OFF". To change the input
status bit, press the On / Off button. In the upper right corner of the display panel, "CV_UN" or "Unreg" is displayed
and "CV_UN "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 loading and unloading constant voltage mode, press Shift + 1 (V_Level) key, the load will return to the
standard constant voltage mode.
4.1.3.3 Soft start constant voltage mode
Soft-start constant voltage mode, equivalent to a capacitive load, the analog capacitance is proportional to the
length of the soft-start rise time, in this mode, the source under test may be subjected to high current moment
Figure 4.8 Soft Start Constant Voltage Mode
In the standard constant voltage mode, press the Shift + 2 (S_Start) key in order to enter the soft start constant
voltage mode, the load display "RISING TM = xxxxxxxxvmS" prompts the current rising edge time, press the number
keys and the decimal point key , Enter the desired rising edge time from high to low, and press Enter key to confirm,
the load enters the soft start constant voltage mode.
