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 )

Operation guide:
 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.
