UT353BT User Manual (PDF)FAQs
Q1: What is the exact difference between the two models?
A: First, both models offer the same ±1.5dB high accuracy. However, the UT353BT decibel meter features built-in Bluetooth technology. Consequently, you can export noise data directly to your smartphone. Thus, it makes professional field reporting incredibly easy.
Q2: When should I use FAST versus SLOW sampling modes?
A: Specifically, the FAST mode responds every 125 milliseconds. Therefore, it is perfect for capturing sudden, short noise peaks. Alternatively, the SLOW mode averages the noise over one full second. As a result, it provides stable readings for continuous background noise.
Q3: Does heavy wind affect the outdoor noise measurement?
A: Yes, strong wind can distort acoustic readings easily. Fortunately, this device includes a specialized wind screen foam cover. Consequently, it effectively filters out harsh wind interference. Ultimately, you receive highly accurate measurements even during outdoor testing.
Q4: How does the maximum and minimum tracking work?
A: Simply press the MAX/MIN button once. First, the screen locks onto the absolute highest noise peak recorded. Next, press it again to view the lowest sound level. Therefore, you can easily monitor fluctuating traffic or factory noise over long periods.
