Which type of meter is recommended for testing a potentiometer?

The recommended type of meter for testing a potentiometer is an analog meter. An analog meter excels in providing a visual representation of resistance changes across a potentiometer, especially since it can show gradual changes in resistance as you adjust the potentiometer's settings. This is particularly useful for applications where subtle variations in resistance are important, such as in tuning circuits or audio equipment.

Analog meters can demonstrate how the resistance varies as the knob of the potentiometer is turned, allowing the user to easily observe trends and identify any irregularities in the potentiometer's performance. The needle movement on the scale gives immediate and continuous feedback, making it advantageous in this context.

While digital multimeters are also capable of measuring resistance, they typically provide discrete readings rather than the smooth, continuous feedback that an analog meter offers. Capacitance meters are designed for measuring capacitance and would not be relevant for a resistance measurement in a potentiometer. An insulation resistance tester is utilized for measuring the quality of electrical insulation, which is unrelated to the function of a potentiometer.
