1 Introduction
Welcome to your new CR:308/CR:310 entry-level sound level meter.
The CR:308 and CR:310 are general-purpose digital sound level meters designed to IEC 61672
Class 2. The instrument has ‘F’ (fast) and ‘S’ (slow) time response and ‘A’ and ‘C’ frequency
weightings. Additional features include max and min hold for the measurement duration, LCpk,
and limit alarm, which you can configure to indicate if your set threshold has been exceeded.
Except for the alarm indication function, the CR:310 includes all the features of the CR:308. In
addition, it can display the Leq value and print results directly from the meter to a portable
printer.
