The CK:261S is a complete noise measurement kit containing a Class 1 Sound Level Meter that has been designed to meet the requirements of ISO 5130-1982 & §29 StVZO for the noise testing of motor vehicles. Designed to be used in workshops, garages and test laboratories alike, the CR:261S is a robust instrument that is simple to operate whilst providing the measurements needed.
The CR:261S has been specifically designed to be used for vehicle noise measurements. In this application, the most commonly used measurement is the maximum sound level, or LAFmax. The instrument has two operating modes.
Stand-alone Mode
This is when the CR:261S is used without the remote control. In this mode, the display shows the current sound level, LAF, and the maximum sound level, LAFmax, recorded.
Remote Control Mode
The second measurement mode uses the remote control to start and stop the measurements. With the remote control unit, ZL:261S, the noise tests can be carried out quickly and comfortably by one person alone - with a single button.
When the remote control is pressed, the instrument will measure and record the LAFmax value. This mode allows noise measurements to be made in accordance with the requirements of ISO 5130:2007 as well as §29 StVZO.
The last three LAFmax measurements are displayed on the screen allowing the user to safely operate or monitor the vehicle under test whilst making the noise measurements.
