Noise
The MT5 load units use forced air (fans) for cooling. At highest speed, fan noise is 86
dB. It is recommended that MT5 load units NOT be located in areas where personnel
work on a regular basis, I.E., not in a laboratory or office environment.
Caution: Continuous exposure to high sound pressure levels, such as those
produced by the Multi-Tracer, are known to cause permanent damage to hearing.
Take appropriate steps to minimize exposure to these harmful sound levels
