When performing constant current output, the output current is less than the set value and CV light is on. It is the open circuit voltage protection. The instrument will automatically switch to constant voltage working state. At this time, check the load or increase the maximum voltage according to the situation. 4. If the fault persists, please contact Hantek. Copyright Qingdao Hantek Electronics Co., LTD HDP10000 series user manual 17
