Operation

The CEL-593 real time analyzer uses the concept of 'Runs' and 'Records' to make noise measurements. In this mode the instrument uses the built in calendar clock to control the capture of noise data. Up to 999 separate Runs can be stored in the instrument memory and each run can save up to 9,999 regular period measurements. A run can then represent a measurement position with the records representing the regular period data sets. The run concept groups the individual period measurements together for easy analysis when recalled from memory or downloaded to a PC. Results can be viewed on screen in row and column format.

In addition to the regular collection of period data the CEL-593 range is also able to store even shorter profiles when used in the broadband mode. The profiles can be either the Leq or the maximum noise level saved at 1 second intervals. This operates as an effective digital level recorder and allows the operator to see the changing noise levels when exported to a PC.

A versatile event recognition system is available in all CEL-593 models that can be triggered from a level exceedance above a user selected threshold or by the operator using the keypad. This can be made to switch on tape recorder to record the audio signal when measurements are made in an unattended situation. The event system can also be used to activate warning signs or other devices to daisy chain multiple instruments together. The Fastore option is included as standard with all CEL-593's. This provides data capture rates up to 200 times per second.

All the CEL-593 models are provided with the CEL-502 RS-232 serial interface and a copy of dB1 software. This allows the instrument to be controlled from the computer and to download the run information at the end of a measurement for viewing, printing and export to a standard spreadsheet program for graphing or further calculations.
