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).
