      "Not an RF meter: nothing about Wi-Fi, cellular, smart meters or cordless phones can be measured with it",
      "A single-axis sensor, so a true magnitude needs the instrument rotated through all three room axes and cannot be read in one shot",
      "No logging, so an overnight or 24-hour record needs the maker's NFA series or an external recorder",
      "Electric-field readings depend on the measurement method and on where the operator stands; the potential-referenced and potential-free figures are not interchangeable"
