General Description; Parts And Controls - CESVA CB006 Manual Del Usuario

1. GENERAL DESCRIPTION

Accurate checking of sound level measuring equipment is essential before and after each
series of measurements
effective yet accurate means of achieving this.
Both calibrators are portable, user-friendly instruments, which makes them ideal to check
sound level meters and sound dose meters on the measurement site or in the laboratory.
They do not need any corrections for environmental conditions.
They may be used with any microphone suitable for closed coupler checking and of ½"
diameter. It is advisable to use them with
05 and P007.
The CB006 and the CB004
as testing frequency, eliminating the need for corrections due to frequency weightings, as
they are unaffected at this frequency.
The CB006 complies with norm IEC 60942:2003 class 1 and the
IEC 60942:2003 class 2.
The CB006 has been specially designed to test class 1 and class 2 dosimeters and sound
level meters and the
Both the CB006 and the
calibrator generates a tone of 94 dB at 1 kHz.
In order to increase the battery life, the calibrator switches off automatically after 5 minutes. It
also has a permanent ON mode, to enable it to be used for longer periods of time.
