General Tools DSM8930 [DSM8930] Digital Sound Level Meter with Analog Bar Graph

The DSM8930 Digital Sound Level Meter. Please read this user’s manual carefully and thoroughly before using the instrument. The DSM8930 uses an integrated condenser microphone to measure the noise level of an environment or the loudness of a machine, typically in order to comply with health and/or safety rules. The meter has a measurement range of 40 to 130 dB over four ranges, an accuracy of ±2 dB, 2 and a digital display resolution of 0.1dB. Real-time measurements are shown on a green backlit LCD in two forms: as a three- or four-digit dB value, and as a moving vertical line on a horizontal analog bar graph. Several features improve the meter’s versatility. Among them are “A” frequency weighting and “fast” (125 ms) time response. The meter can display real-time readings or the minimum or maximum sound levels measured since being powered on.

Physical features of the DSM8930 include a wind shield ball and an analog output jack for connecting to a chart recorder. The DSM8930 is powered by one “9V” battery (included).
