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 aviod the bulb filament from becoming bright and unstable.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.
