Sound Data Recorder DT-173
Long term recording, regular analysis, and management of noise from airports, offices, homes, schools, and hospitals.
Product details
1. Compliant with IEC61672-1 CLASS2
2. Norm (Normal), PEAK mode selection
3. Measurement of maximum and minimum values
4. Value alarm indication
5. A and C weighted network selection
6. Fast (FAST) Slow (SLOW) Response Time Selection
7. Manual and Automatic start selection
Note:
1. The Norm mode measures 20 data points (once every 50ms), stores the average of the 20 data points, and takes a PEAK MAX value from all 20 data pointsA PEAK MIN value. When the sampling rate is greater than 10 seconds, this mode will turn off the peripheral power supply to save power before the sampling time, consuming only about 30uA of current.
2. In PEAK mode, DataLogger always measures data at intervals of 50ms, and PEAK values are the maximum and minimum values of the entire working process, rather than the maximum and minimum values of the sampling points. The sampling data stored at the sampling point is the largest among the 20 sampling points, rather than the average value.
