校正程序 (CALIBRATION PROCEDURES)
If the calibrated " SOUND LEVEL METER " used the 0.5" microphone, then on the " Couple Section " should install the " 0.5" Mic. Adapter " first.
Consideration :
If the calibrated " SOUND LEVEL METER " used the 1 inch microphone, then on the " Couple Section " should take away the " 0.5" Mic. Adapter ".
Insert the microphone of calibrated " SOUND LEVEL METER " carefully all the way into the coupler section of the Sound Calibrator.
Set the calibrated " SOUND LEVEL METER " to a range suitable for measuring " 94 dB ".
Set the " Off/BAT. TEST/On Switch " to " ON " position. A pure 1,000 Hz tone is produced.
Adjust the calibration VR (knob) of the " Sound Level Meter ". until that the display reach to 94.0 dB exactly.
校準程序
-
1.麥克風轉接器：
如果使用 0.5 吋麥克風，請在耦合部分安裝 0.5 吋麥克風轉接器。
如果使用 1 吋麥克風，請移除 0.5 吋麥克風轉接器。
-
2.插入麥克風： 小心地將聲級計的麥克風插入聲音校準器的耦合器部分。
-
3.設定聲級計： 將聲級計調整到適合測量94 dB的範圍。
-
4.開機： 將「Off/BAT.TEST/On Switch」設定為「ON」位置，即可產生純淨的1000Hz音調。
-
5.調整校準： 調整聲級計的校正 VR（旋鈕），直到顯示幕剛好顯示 94.0 dB。
