INTRODUCTION This comp act sound level calibrator is a portable, battery operated sound source, suitable for ma ny portable sound level me ters. Wh en a mi crophone from a sound level me ter is inserted into this calibrator, the sound level me ter picks up the signal and displays the signal in dB (decibel) units. The sound level me ter should be adjusted (if necessary) to ma tch the calibrator's output signal as closely as possible.
Features: Meet IEC 60942:2018, class 2 standard Suitable for all sound level meter with microphone head mechanical compliant with IEC 61094-1 or IEC 61094-4, such as 23.8/13.2/12.2 and 7mm Calibration frequency at 1K Hz with three level 114dB, 94dB and 104dB Vivid LED display with stability and low power indicator Power up by batteries, easy to carry around MATERIAL SUPPLIED A complete sound level calibrator package contains of the following items.
CAUTION 1. Before operation, leave the calibrator in stable room temperature for at least 2 hours to make calibrator reach temperature equilibrium. 2. Make sure the microphone and the calibrator are correctly aligned during insertion because the microphone could be damaged if not inserted squarely, or if inserted at speed or if excessive force is used. 3. The calibrator need to be placed on a flat surface.
OPERATION Refer to above Caution section in page 3 to ensure the calibrator is ready to use. Carefully insert microphone up to the stop within the calibrator cavity. The O-ring will offer some resistance. POWER ON/OFF Press power key briefly to turn on. The green power and dB LED will flash for 10 seconds till system warm up time is completed.
TROUBLESHOOTING ? DB LED keep flashing and running in cycle and generated sound always stay the same, no change. Why? Root cause Hardware error Solution Call for after sales service. ?Why power key is red LED? Root cause Battery power is too low to operate Solution Change or charge batteries. ?
