Before using the multimeter, you should perform "mechanical zero adjustment", that is, when there is no measured power, make the pointer of the multimeter point to the position of zero voltage or zero current.2. In the process of using the multimeter, you can not touch the metal part of the test pen with your hands, so that on the one hand, it can ensure the accuracy of the measurement, on the other hand, it can also ensure your safety.3. When measuring a certain amount of electricity, you cannot shift 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.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.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.Package List:1 x Oscilloscope Multimeter ( Battery Not Included)2 x Test Lead1 x Manual Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
