How does a multimeter measure voltage? Multimeter voltage measurement formula
The formula for measuring voltage with a multimeter, the precautions when measuring voltage with a multimeter, be clear about the internal resistance of the meter, the circuit meter under test is connected in parallel, the range cannot be changed when it is charged, and when measuring DC voltage, find out the positive and negative poles of the circuit, etc.
Multimeter voltage measurement formula
There are eight precautions for measuring voltage with a multimeter. Know the size of the internal resistance of the meter, and someone must monitor it. The circuit meter under test is connected in parallel, and the range cannot be changed when it is charged.
When measuring DC voltage, find out the positive and negative poles of the circuit. Measure the voltage of the inductive reactance circuit, and do not cut off the power supply during the period. To test kV high voltage, a special test lead wire is required.
Induced electricity-to-ground voltage, the difference between different ranges is large.
