What are the advantages of DMMs?
What will be an ideal response?
Advantages of DMMs are:
- They have a digital display instead of a needle.
- The high-input resistance prevents the meter from drawing current while it is connected to a circuit. This protects the circuit and keeps readings accurate.
- They are often self-scaling so adjustments are not required.
- They do not have to be connected in the correct polarity. A plus or minus ID is displayed on the screen with the reading.
