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
Old test equipment misses modern electrical faults. Here's why power quality analyzers, True RMS clamp meters, and diagnostic insulation testers aren't optional anymore—and what the Hioki PQ3198, CM4376, 1555, and C5 bring to the table.

A practical comparison of the Hioki DT4256 multimeter, insulation testers, the Hioki PQ3198 power quality analyzer, and thermal imagers—written by an admin buyer who manages the budget. Covers automotive multimeter needs, how to use a megger insulation tester, and the real cost of cheap test equipment.

Our plant's $14 multimeters produced a reading that looked fine — and cost us a rebuilt motor. Here's how we upgraded to Hioki's IR4053-10 insulation tester and 3196 power quality analyzer, plus what I learned about buying distance sensors and IFM inductive sensors online.
