What does a high impedance meter do?

A high impedance meter is designed to measure voltage and current with minimal impact on the circuit being tested. It has a very high input resistance, typically in the megaohm range, which prevents it from drawing significant current and altering the circuit's behavior. This makes it ideal for measuring sensitive electronic components and circuits without affecting their operation. High impedance meters are commonly used in applications such as electronics diagnostics and troubleshooting.
