Measurement notes
These notes are written for engineers who need practical measurement decisions: what to document, which conditions change the reading, and how to keep the service record close to the instrument history.

Most electrical troubleshooting failures aren't caused by faulty components — they're caused by testing strategies that ask the wrong questions. A multimeter reading 'fine' can still miss insulation breakdown, failed filter capacitors, intermittent vibration faults, and thermal reflections through glass. Here's the fix, with practical tool choices from Hioki's range.
