Format: Markdown version of the HTML page (same content, lookups and page chrome left out).

Test and measurement equipment, with safety first. Use meters and probes rated for the job (CAT II, III or IV for the circuit you are measuring), test your tester on a known live source, and follow OSHA and NFPA 70E for lockout and arc flash PPE. For measurements that matter, calibration should be traceable to NIST through an accredited lab. Makers and stores below are commercial.
