CEL-630 Series Sound Level Meters Applications Occupational Noise Measurement • Workplace noise assessments according to ISO9612 • Selection of hearing protection • Calculation of noise exposure • Ensuring compliance with workplace noise legislation Environmental Noise Measurement • • • • Designed to make occupational and environmental noise measurements with confidence! The CEL-630 is an easy to use instrument designed to undertake the measurement requirements of workplace and environmental noise. It also complies with the latest IEC and ANSI international standards for sound level meters. Just switch on the instrument, auto-calibrate and start measuring with one of the predefined views. Regardless of the view selected, all data is measured and stored simultaneously so no mistakes can be made. By implementing the latest digital technology, the meter has a single measurement range so no range adjustment is required, ensuring the highest levels of performance with all noise sources. Models are available for both environmental and/or occupational noise with the availability of frequency analysis and advance functions such as data markers, timers and logging of time history data. Even with such advanced functionality, the CEL-630 Series remains very simple to use. Audio recording is a standard feature of the CEL-630, all models having a voice notes capability. This allows you to speak into the microphone before or after a measurement in order to annotate the result, so you don’t need to write things down. Data can also be ‘marked’ during a measurement to signify either an anomalous or significant event and audio is also recorded for later noise source identification. If the instrument is used for unattended measurements, audio recording can be triggered by a condition such as a given level being exceeded for a period of time. In this case additional data will be collected along with the audio. This can be especially useful where the noise source of interest is transient.

Record Voice Notes Once the ‘play’ key has been pressed you can record an audio (voice) note to define the measurement. Once this is done your measurement will begin. When the measurement is started the status bars at the top and bottom of the screen go green (like a traffic light), when the measurement is stopped the bars go red. During a measurement, simply press the ‘view’ key to scroll through the data. All parameters are stored together so there is no need for multiple measurements. Once the measurement is stopped, data can be reviewed in the instrument memory. • Record voice notes to identify...
