What is the main purpose of using in-circuit meters?

The primary purpose of using in-circuit meters is to monitor device operation. In-circuit meters are specifically designed to measure various electrical parameters such as voltage, current, and resistance while the circuit is in its operational state. This capability allows technicians and engineers to observe how the circuit behaves under real-world conditions, making it easier to diagnose issues, verify performance, and ensure that the device is functioning as intended.

Monitoring device operation is crucial for troubleshooting, ensuring reliability, and optimizing performance during the design and testing phases of electronic devices. These readings provide insight into how components interact and can reveal problems that might not be evident when the circuit is powered down or tested in isolation.
