    The 400FL is individually calibrated with 120 divisions and is ideal for dB measurements. It incorporates an HP taut-band mirror-backed logarithmic meter. A range switch changes sensitivity in 10dB steps which, combined with the 12 dB scale, provides the overlap desirable in decibel-level measurements.
