If the reading or measurement is unreliable so do the outcome of the circuit we have designed. This test gear is impressive in term of it features but when I go through the manual, I am disappointed to find out how little info provided in the manual. The manufacturer should have provided more info. Here are one example of one of the features that I considered important : 21 SOUND LEVEL (dB) MEASURING WARNING To avoid damage to the meter, input plug can not connect with any electric signal. 4.21.1 Set the transform switch at the dB range position. 4.21.2 Move the sensor in front of the meter to the sound source in a horizontal position. 4.21.3 The ‘LCD’ display will show the current sound level (dB). NOTE: •The Fast response is suitable to measure sudden bursts and peak values from sound source. • Strong wind (over 10m/sec.) striking the microphone call cause misreading for measurement in windy locations, a windscreen should be used in front of microphone.
