Instruction Sheet
The Sound Level Microphone for the Micromate monitoring
unit, automates noise monitoring from building activities,
construction, traffic, and mining operations. The Micromate
monitoring unit combines noise and vibration monitoring in
the same unit, making it a cost effective and flexible device for
these applications.
The Sound Level Microphone meets the requirements for IEC
61672 Class 1, including A and C weighted specifications and
has a measuring range from 30 dB to 140 dB with a Fast or Slow
response.
There are four record modes to choose from:
• Manual trigger
• Waveform (records up to 90 seconds, once triggered)
• Histogram (2 seconds to 30 minute intervals)
• Histogram-Combo (records both Histogram and Waveform
simultaneously)
