Multimeter mechanical zero calibration
Put the multimeter flat on a relatively level surface, do not put it on plexiglass or a table with static electricity, use a flat-blade screwdriver to slowly adjust the plastic screw under the surface dial, and adjust the needle to the left zero position, it is best to shake it. Three times, adjust it three times, and it will return to zero after every shake.
Multimeters, also known as multiplex meters, multimeters, triple meters, multimeters, etc., are indispensable measuring instruments in power electronics and other departments. Generally, the main purpose is to measure voltage, current and resistance.
The multimeter is divided into pointer multimeter and digital multimeter according to the display mode. It is a multi-function and multi-range measuring instrument. Generally, the multimeter can measure DC current, DC voltage, AC current, AC voltage, resistance and audio level, etc., and some can also Measure AC current, capacitance, inductance and some parameters of semiconductors (such as β), etc.
