第1级 数据记录 digital

数据记录功能与设备中的日期和时间......以及使用MicroSD（4 GB）存储卡（包括交付）的数据传输，RS-232或USB不同的声压级，例如example, Laeq, LcPeak, LaF, LaFMax, LaFMin, SD, SEL, E Ideal for measurements for workplaces which are outdoors, e.g. at airports, on building sites, in road construction etc. with broad access to spectrum thanks to the highly-accurate 24-Bit A/D converter Floating point evaluation for higher level of accuracy and better stability The optimised analogue frontend switch reduces the ambient noise and increases the linear measuring range A specially-developed algorithm permits a compliant dynamic range of more than 120 dB! (SW 1000: > 123 dB; SW 2000: > 122 dB) Three profiles and 14 user-defined measurements can be calculated in parallel with different frequency and time weighting LN statistics and display of the graph showing the progression of time User-defined integral interval measurement up to a maximum of 24 hours is possible Frequency weighting (filter) A, B, C, Z Time interval during measurement: F (fast), S (slow), I (pulse) Freely-definable limits for the output of an optical alarm signal Peak Hold Mode to capture peaks Octavo function for targeted sound analysis TRACK function with graphic display of a measurement Calibration mode (with optional calibrator) Trigger mode: Analogue signal to switch the device on or off with 3.5 mm plug Automatic measurement for timer function is possible
