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.
Technical note
A procurement manager's honest take on buying multimeters—why a $60 Klein can cost more than a Hioki DT4282, what the Fluke 45 is still for, and how to use a FLIR ONE thermal camera.

A maintenance engineer's hard-earned lessons on electrical measurement: why the Hioki clamp meter is rarely the source of wrong readings. Covers test lead failures, voltage vs. current mistakes, true RMS on VFD circuits, IO-Link encoder diagnostics, calibration limits, and a pre-measurement checklist.
