Instrument Introduction
The instrument covered by this handbook is an analogue sound level
meter built into our award winning, tough die-cast body, which is
both stylish and ergonomically designed. The instrument has ‘A’
weighting and ‘LIN’ (linear) frequency responses as well as a set of
ten octave band filters. The filter’s ‘AUTO’ facility allows a chart
recorder to display the results of a noise spectrum analysis. ‘SLOW’,
‘FAST’ and ‘PEAK’ responses are available. A maximum hold but-
ton, ‘MAX’, allows the accurate recording of the ‘maximum rms’ of
a transient noise event. The instrument conforms to the relevant sec-
tions of BS5969, IEC651, ANSIS1.4, BS2475 and BS EN60651
standards.
