The moving coil meter is recognized for its high accuracy, especially in measuring direct current (DC) and low-frequency alternating current (AC). This type of meter operates on the principle that a current-carrying coil placed in a magnetic field experiences a force that causes it to move. The degree of movement is proportional to the current passing through the coil, allowing for precise measurement.

Moving coil meters typically have a very linear scale and are less prone to errors compared to some other types of meters, making them ideal for applications requiring precise readings. Additionally, their construction can provide good thermal stability and low hysteresis, which contributes to maintaining accuracy over a range of temperatures and conditions.

In contrast, digital meters also offer high accuracy but may rely on calibration and processing that could introduce variability. Inductive and capacitive meters, while useful for specific applications, may not provide the same level of accuracy in general measurements as moving coil meters due to their design and operating principles.
