CAL 300
ACOUSTIC CALIBRATOR
DESCRIPTIONS
The acoustic calibrator is the key accessory to calibrate measurement system.
The acoustic source is defined in pressure level and in transmitting reference, it corresponds to the
current
class 1
standards : NF EN 60942 : 2003 and CEI 60942 : 2003.
It delivers two acoustic pressure levels according to your selection : 94dB or 114dB with a 1000 Hz
frequency.
This calibrator is designed to remain compatible with microphones of different diameters.
See
technical specifications.
Calibration of a sound level meter is done in pressure in the cavity of the calibrator. The sound level
meter being generally used in free field, please observe the free field correction term indicated in its
user manual. It is the same in case of diffuse field using.
Flashing green or orange light : wait
Stabilized green or orange light : calibration is ready
Red light : change batteries
Button : select the acoustic
pressure level : 94 or 114dB and
launch calibration
Microphone and adapter ring coupler
