(4) Low battery indicator. (5) The 1/2” adapter. I. Feature II. Specification III. Instrumentation (1) Open the battery cover, and insert the battery in position. (2) Choosing a suitable adapter and plug into the Sound-Level Calibrator. (3) With suitable plug of microphone, and plug into the adapter all the way down of the Sound-Level Calibrator. (4) Turn on power switch and set sound level to 94dB or 114dB Position. (5) Read the level on the microphone instrument under test and adjust the sensitivity control for the correct indication of the Sound-Level Calibrator level selected in step. IV. Test Procedure (1) Use the Sound-Level Calibrator as specified in this manual; otherwise, the protection provided by this meter may be impaired. (2) When using Sound-Level Calibrator, environment noise level should less then 10dB of output sound. (3) Environment conditions a. Altitude up to 2000 meters. b. Relative humidity up to 90%. c. Operation ambient 0~40 ℃ (32~104℉). (4) Replace the battery for keep measuring correctly, if LED indicator light off. (5) If long time not in use, we recommend to take out the battery to decrease the battery leaking which could damage the Sound-Level Calibrator. V. Notice
