The instrument has ‘F’ (Fast) response and both ‘A’ and ‘C’ frequency weightings. In addition facilities are provided to hold the maximum reading occurring during the measurement period.

The CR:306 allows noise levels to be checked quickly and simply, with the large display showing the Sound Level (SPL) with the standard dB(A) frequency weighting. dB(C) Frequency Weighting is also provided.

The instrument has two measurement ranges, and can measure from 35dB(A) to 130dB(A). The maximum hold function allows the unit to freeze the display showing the highest level measured. This can be used where the allowable level is given in terms of a maximum (LAFmax or LCFmax).
