diagnostic device
Problem detection tool
A diagnostic device is an instrument or tool used to identify problems, conditions, or malfunctions.
In medicine, diagnostic devices range from simple thermometers to MRI machines—anything that helps detect or monitor disease.
In automotive and technical contexts, a diagnostic device reads error codes or tests systems: The mechanic hooked up a diagnostic device to check the engine.
The term emphasizes the device's purpose: finding out what's wrong rather than fixing it.
