1. To ensure proper operation of the equipment, please use it only within the environmental specifications provided in the product manual.
2. When the probe or test leads are connected to power lines, do not insert or remove them.
3. Avoid direct sunlight on the display screen: exposure to sunlight not only affects observation, but also ages the LCD screen and shortens its life.
4. pay attention to moisture. Humidity will not only reduce the insulation performance of high-voltage components and cause sparking, but also metal printed copper foil and component pins are easily corroded and damaged.
5. Keep the cooling holes unobstructed to prevent blockage.
6. When the instrument is out of order, please contact a professional for maintenance. In the process of use, abnormal phenomena such as smoking and burning smell should be cut off immediately to avoid further losses;
