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.

3.2如果负载不能启动用下面的方法可以帮助来解决在打开负载时您可能遇到的问题。

1) 检查电源线是否接好应先检查电源线是否接好，负载是否已经被供电，电源开关是否被打开。

2) 检查负载的电源电压设定负载的工作电压为110V或220V两种方式，检查您的负载的电压设置是否和供电电压相匹配。

3) 检查负载的保险丝是否烧坏若保险丝烧坏，请您用下表中的保险丝规格来替换。
