In situations where tuned circuits are involved, an instrument with an analog readout can be particularly advantageous. This is primarily because analog meters often provide a smoother and more continuous visual representation of changes in the measurement. When adjusting tuned circuits, such as those in radio transmitters or receivers, the operator can visually observe how the circuit responds to adjustments in real-time.

The needle movement on an analog meter can indicate the peak response or resonance more intuitively, revealing subtle changes that may not be as easily discernible with a digital readout. Additionally, analog instruments might facilitate quicker and more instinctive reactions from the operator, allowing them to tune the circuit more effectively by responding to the needle's movement as they make adjustments. This can be vital in ensuring optimal performance of the tuned circuit, especially in radio applications where specific frequency responses are critical.

While other types of measurements might be best served by digital readouts for their precision and clarity, the analog readout's fluidity and immediacy make it particularly useful during the tuning process.
