Simple operation supports a wide range of noise measurements.
The ordinary noise meter NL-22 is equipped with a built-in serial interface. By using this interface, you can set the measurement conditions and control measurements of the NL-22 via commands from a computer, as well as transfer current data and data stored in the built-in memory to the computer. 【Compact Flash Card Compatible】Direct recording to a large-capacity memory card is possible. A standard 16MB card is included, which can store approximately 100,000 sets of calculated data such as Leq, or about 1,000,000 noise level readings (equivalent to 1.3 days of continuous data) at 100-millisecond intervals. (Cards with optimal capacity can be installed according to the measurement.) 【Comparator Function】Equipped with a comparator output function via an open collector output. Settings can be made in 1dB steps between 30 and 130dB. (Maximum applied voltage: DC24V; maximum current: DC60mA)
