BenchPicked data
EMF meter field-coverage matrix
Published field modes, frequency ranges, axis context, accuracy statements, and measurement boundaries for consumer screening meters.
Correction to the historical record
The downloads remain the original September 24 version. The abbreviated accuracy in its TF2 record is incomplete; use the qualification below and the current page-bound exports, not the historical shorthand as a full-band claim.
- 2026-10-12: +/-5% at 50/60 Hz. Manufacturer specification at the stated reference frequencies, not independent validation or a full-band error bound. Official specification table · Current research JSON · Current field CSV
What the data represents
The matrix separates field mode, frequency range, axis context, published accuracy, and consumer-screening use so a broad label such as EMF meter is not treated as proof of equivalent coverage.
Published specifications describe instrument scope. They do not establish BenchPicked-measured accuracy, medical risk, shielding efficacy, or professional compliance suitability.
