Multimeter vs. Ohmmeter: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on February 14, 2024
A multimeter measures various electrical properties like voltage, current, and resistance, whereas an ohmmeter specifically measures resistance.
Key Differences
A multimeter is a versatile tool used for measuring voltage, current, and resistance. An ohmmeter is a specialized instrument designed solely for measuring electrical resistance.
Multimeters are used in a wide range of electrical and electronic testing scenarios. Ohmmeters are specifically used when the primary interest is in checking or measuring resistance.
Multimeters can switch between various functions, making them suitable for diverse electrical diagnostics. Ohmmeters, being dedicated to resistance measurement, have limited functionality compared to multimeters.
Multimeters often come with more complex features, including digital displays, multiple measurement scales, and sometimes advanced functions like capacitance measurement. Ohmmeters are typically simpler, focusing on accurate resistance readings.
Multimeters are essential in the toolkit of electricians and electronic technicians due to their broad application range. Ohmmeters are useful in specific contexts, such as checking circuit continuity or the integrity of a conductor.
