Some formulas for using a multimeter Digital
Correct use of the multimeter can not only quickly determine the fault location, but also prevent damage to electrical equipment and the multimeter itself. Below I will talk about some formulas for using a multimeter.
Measure first, look at the block, don't look, don't measure
Do not switch gears when measuring, switch to neutral gear after measurement
The dial should be level and the readings should be aligned
The range should be appropriate, and the reading should be correct
Test R is not charged, test C is discharged first
Measure R and adjust to zero first, and adjust to zero when shifting gears.
The black and negative must be remembered clearly, the black in the table is connected to +
Test I should be connected in series, and test U should be connected in parallel
Polarity is not reversed, one hand becomes a habit
