The Cirrus CR 262 is a simple to use Type 2 broadband integrating sound level meter. The instrument is designed to be used without the need for complicated setup, and provide the essential functions needed from a modern sound level meter.
Sound Level dBA, Equivalent Continuous Sound Level LAeq, Peak Sound Pressure (LCPeak), Maximum Sound Level (LAFmax), Minimum Sound Level (LAFmin), are all parameters that can be evaluated using this meter.
The very clear, simple interface and large display allows the instruments to be used quickly and with very little or no training. Press the Cal key to calibrate the instrument, and select an appropriate measurement range using the arrow keys. The Start & Stop keys control the measurement, and the Graph key allows the user to switch between the numerical and graphical display.
During the measurement, the instrument displays all of the current parameters, with a quasi-analog bar graph representing the current sound level. At the end of the measurement, all of the parameters are displayed on the screen at the same time. The last measurement is stored and is displayed when the instrument is next switched on.
Sound level meter manufactured to IEC 61672-1:2002 Class 2 Group X, IEC 60651:1979 Type 2, IEC 60804:1985 Type 2 and ANSI S1.4 with NK:70 random incidence adaptor fitted.
Range (typical): Broadband 26dB(A) to 140dB(A) and 143dB(C) Peak (70 to 140dB Range)
