To check a meter to see if it has high impedance, turn the selector to the direct current (DC) volts position.

Question

Quizplus · Accepted Answer

When the selector is turned to the DC volts position, the meter's resistance will be in series with the circuit being measured, which will only allow a small amount of current to flow. A high impedance meter will have a very high resistance and will not draw much current from the circuit, indicating that it has high impedance.
