Introduction
Congratulations on your purchase of the Extech 407355 Personal Noise Dosimeter. The 407355 is
designed to test noise exposure in accordance with OSHA, MSHA, DOD, ACGIH, and ISO standards.
Fast and easy on-site surveys help determine noise reduction requirements. The meter can also be
used in SLM (sound level meter) mode where sound pressure levels are monitored from 70 to 140dB.
The SLM (sound level meter) mode has a datalogging feature that can record up to 8800 readings
which can be downloaded to a PC for analysis. Please visit our website (www.extech.com) to check for
the latest version of this User Guide, Product Updates, and Customer Support.
The built-in RS-232 PC interface offers the following capabilities:
In SOUND LEVEL METER (SLM) MODE: The meter can be connected to PC while taking
measurements so that readings can be stored in a file and readings can be viewed in a
variety of display configurations (graph, list, etc.).
In DOSIMETER mode: The meter can perform a noise survey after which the user can
transfer the survey data to a PC.
Note: In DOSIMETER mode, the individual measurements are NOT logged and cannot be
recalled.
Careful use of this device will provide years of reliable service.
