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. Note: In DOSIMETER mode, the individual
measurements are NOT datalogged and cannot be recalled.
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.
Careful use of this device will provide years of reliable service.
