The instrument should be placed in a dry room. When used, it should be placed on a firm and stable workbench. The indoor lighting should not be too strong. In the hot weather, you can not use the fan to blow directly to the instrument to prevent the bulb filament from becoming bright and unstable. 2. Before using the instrument, the user should first understand the structure and working principle of the instrument, as well as the functions of each control knob. Before the power is turned on, the safety performance of the instrument should be checked. The power supply wiring should be firm and the power supply should be good. The starting position of each adjustment knob should be correct, and then press the power switch. 3. When the instrument has not been powered on, the meter pointer must be on the “O” engraving line. If this is not the case, you can adjust it with the calibration screw on the meter.
