Constant current operation mode (CC).2. Constant voltage operation mode (CV).3. Constant resistance operation mode (CR).4. Constant power operation mode (CW).4.1.1 Constant current operation mode(CC)As shown in the following figure, in the constant current mode, the electronic load consumes a constant current regardless of whether the input voltage changes. Please note that if the maximum current value of the source is less than the given constant current value, the load will not be guaranteed to be set to the given current value and the voltage to be tested will also be pulled down.4.1.1.1 Standard constant current modePress the I-SET button, the load shows "STANDARD CURR = xxxxxxxxA", showing the current value. Then you can press the number keys and decimal point keys on the panel and input the required constant current value from high to low, and p ress “Enter” to confirm that the load goes to the standard constant current mode.If the input status is ON, the upper right corner of the display panel shows "OFF". If you want to change the input state to “ON”, press the On / Off button, then "CC" or "Unreg" is displayed in the upper right corner of the display panel. The display "CC" indicates the expected constant current value; "Unreg" indicates thatthe load cannot be correctly adjusted to the given current value. Please check whether the source to be tested is properly connected and turned on or whether the source to be measured can output a preset current value.At this point, if you want to fine-tune the set current value, you canuse the rotary encoder in upper right corner, clockwise adjustment to increase, counterclockwise adjustment to reduce, please note that if the given current value has reached the maximum which is limited by load, the current value cannot be adjusted upwards. In this case, the current value is indicated on the lower right side of the display panel, and one of the numbers has a cursor, Indicating that the current fine fineness is one unit of the current position. If the user wishes to change the fineness of the adjustment, the rotary encoder can be pressed down. The rotary encoder contains a key, once this button is pressed, the cursor will movea grid In order to achieve the adjustment of fineness adjustment.4.1.1.2 Loading and unloading constant current modeThe loading and unloading mode is a kind of protection to the measured source. When the source voltage is just beginning to climb, the load is automatically adjusted to the open state until the source voltage reaches the ONSET and the load is adjusted to set the constant current value. When the source voltage to be measured begins to fall and falls to the OFFSET unloading voltage, the load is automatically adjusted to an open state. If the ONSET load voltage is greater than the OFFSET unloading voltage, the load will likely avoid frequent loading and unloading near the critical point of the unloading voltage, which can better protect the source to be tested.In the standard constant current mode, press the Shift + 1 (V_Level)key to enter the loading and unloading constant current mode. At this time, the load display "ONSETVOLT = xxxxxxxxV", prompting the current load voltage.
