Which of the following is NOT a basic operations DMMs help us to perform?

• Convert Electrical Signals into Understandable Values

• Perform highly accurate electrical measurements

• Test mechanical systems

• Solve electrical equation calculations

Define High Impedance. Why is it important when testing electronic circuits?

• High impedance is a state where a circuit or component has a very high resistance to current flow, minimizing the loading effect on the circuit being tested.

• High impedance is a state where a circuit or component has a very low resistance to current flow, maximizing the loading effect on the circuit being tested.

• High impedance is a state where a circuit or component has a moderate resistance to current flow, balancing the loading effect on the circuit being tested.

• High impedance is a state where a circuit or component has no resistance to current flow, eliminating the loading effect on the circuit being tested.

When using measuring instruments, be sure to use an instrument that has a rating of LESS than the highest value of electricity that you expect to be measuring
