Before use, the two current adjustment knobs must be counterclockwise to zero. If they do not return to zero and the connected voltage is too high,if it exceeds 150W, it may directly burn the load. 2. When connecting to the test power supply adjustment, you must also adjust slowly, because it is an analog device, if it is adjusted quickly, the display does not respond in time. If the power is exceeded, the load may be burned.
