Matters needing attention in the use of multimeter
(1) The multimeter should be "mechanically zeroed" before use, that is, when no electricity is measured? , so that the multimeter pointer is at zero voltage or zero current position.
(2) When using a multimeter, you can't touch the metal part of the stylus with your hands? On the one hand, this can ensure the accuracy of measurement, on the other hand, it can also ensure personal safety.
(3) When measuring a certain amount of electricity, it is not allowed to shift gears at the same time, especially when measuring high voltage or high current. Otherwise the multimeter will be destroyed. If it is necessary to shift gears, the probe should be disconnected first and then measured after shifting gears.
(4) When using the multimeter, it must be placed horizontally to avoid mistakes. At the same time? Also pay attention to avoid the influence of external magnetic field on multimeter.
(5) After using the multimeter, place the transfer switch in the maximum range of AC voltage. What if you don't use it for a long time? The battery inside the multimeter should also be taken out to prevent the battery from corroding other devices in the meter.
Multimeter is mainly a special instrument for measuring AC /DC voltage and resistance or DC current, which is often used in electrician and radio work. There are many brands and models of multimeters, but the use methods are basically the same. Therefore, in the purchase of multimeters, we should pay more attention to quality problems. It is more cost-effective to choose a good quality multimeter brand under the condition that the use method is roughly the same. The above is the related content of Shengli multimeter introduced by Bian Xiao, hoping to help everyone.
