This can ensure the accuracy of the measurement on the one hand, and ensure your safety on the other hand._x005f_x000D_ (3) When measuring a certain amount of electricity, it is not possible to transform gears while measuring, especially when measuring high voltage or large current, you should pay more attention. Otherwise, the multimeter will be destroyed. If you need to change gears, you should disconnect the meter pen first, and then measure after the gear shift._x005f_x000D_ (4) When the multimeter is in use, it must be placed horizontally to avoid errors. At the same time, attention should be paid to avoid the influence of external magnetic fields on the multimeter._x005f_x000D_ (5) After the multimeter is used, the transfer switch should be set to the maximum range of AC voltage. If you do not use it for a long time, you should also take out the battery inside the multimeter to prevent the battery from corroding other components in the meter.
