Troubleshooting in instrumentation begins with which step?

Troubleshooting in instrumentation primarily starts with the step of verifying that a problem exists. This initial verification is crucial because it ensures that any further investigation or analysis is warranted. If a technician jumps straight into identifying the cause or trying to locate the problem without confirming the existence of an issue, they may end up wasting time and resources on a non-existent fault.

Verifying a problem involves gathering data, checking system readings, and determining if the observed behavior deviates from expected performance. This step establishes a foundation for the troubleshooting process, allowing technicians to focus their efforts accurately on existing issues and ensuring that corrective actions are based on verified conditions rather than assumptions.

Once it is confirmed that a problem exists, technicians can proceed to locate the source of the problem and identify its cause, which are critical subsequent steps in effective troubleshooting.
