Calibration Procedures: (Pls use a Standard Acoustic Calibrator)
1. Make the setting: Display: SPL(dBA) Time/Weighting: Fast/Level range: 60~110dB /Measurement mode: MAX function disable | |
2. Insert the microphone carefully into to the 1/2 inch hole of the Calibration | |
3. Turn on the Calibrator and adjust the Protentiom eter in side the battery compartment of the unit (shown in the diagram 1), The level of the units ( show in the diagram 1), The level display will indicate the desired level(94.0) our products are all well calibrated before shipment (Recommended recalibration cycle; 1 year ) |
1. Turn on power ( pls install battery first before power on) | |
2. Select the desired response and weighting, also select desired rang. | |
3. If weighting for general mosie sound level, pls select dBA. | |
4. If the sound source consists of the short brusts of only catching sound peak, set response to FAST, to measuring average sound level. use the slow setting | |
5. When MAX mode is chosen, The instrment captures and hold the maximum noise level. |
