1. space and remove batteries in case of long period of inactivity Despite these recommendations grader stays an extremly reliable device easy to use and with few maintenance Simply replace batteries when they are worm and make a regular checking MAINTENANCE CAL200 calibrator is linked to national standars As part of quality insurance standards we recommend performing an annual checking SUPPIED WITH CAL200 is supplied with its user manual two alkaline batteries and an adapter ring for inch microphone TECHNICAL FEATURES Main level of acoustic pressure Main frequency Distortion Authorization for calibration Transmission time Standards Accuracy CE marking Compatible microphone Standard ambient conditions Operating conditions Power supply Autonomy at 20 C Storage Overall dimensions Weight 94 dB 0 4 dB 1000 Hz 5 Hz DHT lt 3 Green light 1 minute NF EN 60942 2003 CEI 60942 2003 Class 2 As per to European Directive 89 336 CEE and Standard product 1 inch microphone without adapter according CEI 61094 4 standard Y2 inch with BC12 ring 10 mm microphone with BC10 ring 3 8 inch microphone with BC38 ring Other microphones with suitable rings 23 C 50 RH 1013 hPa 0 C to 40 C 25 to 90 RH 650 hPa at 1080 hPa 2 alkaline batteries 1 5 V CEI AAA LRO3 type More than 1500 calibrations From 0 C to 60 C Length 185 mm Wid2. KIMO INSTRUMENTS Pressure Temperature Humidity Air velocity Airflow Sound level CAL 200 ACOUSTIC CALIBRATOR The acoustic calibrator is the key accessory to calibrate acoustic measurement systems The acoustic source is defined in pressure level and in transmitting frequency it corresponds to the current class 2 standards NF EN 60942 2003 and CEI 60942 2003 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 observe the free field correction term indicated in its user manual It is the same in case of diffuse field using DESCRIPTION Green light calibration is ready Button launch Red light wait calibration Microphone and adapter ring coupler CALIBRATION gt Insert the adapter ring according to microphone diameter of the device to calibrate Ensure that the ring is correctly positionned it has to come to a stop down of the calibrator housing gt Put the calibrator on the microphone until the microphone comes to a stop down of the ring Perform this move slowly and smoothly so as not to damage the microphone Prefer to put vertically the soud level meter and the microphone gt Press the button situated in front face of the calibrator A red light flashes gt Wait for a
