3. Intended use
This sound level detector is a digital meter for measuring the sound level in decibels (dB).
The sound level detectors meet the requirements of EN 61672-1:2014-07 (IEC 61672:2013).
Model SL-200 has the accuracy class 2 for general field examinations (e.g. operations tests) and
Model SL-100 has the accuracy class 3 for orientation measurements (e.g. to determine whether
a particular noise limit has been exceeded).
The values detected and the momentary units/functions are displayed digitally on a large LCD
(Liquid Crystal Display).
Two frequency evaluation filters (A/C) and two time evaluations can be preselected and allow
the device to be used universally.
The measurement has a range of 31.5 Hz to 8 KHz as well as a sound level of 30 to 130 dB.
The maximum value and the details shown on the display can both be stored.
To suppress troublesome wind noise, the device is delivered with an attachable windscreen.
This does not impair correct measurement of the sound level.
For Model SL-200, the lighting of the display can be selected manually.
A 9-V block battery (type 1604A) is required for operation.
Measurements must not be carried out under unfavourable ambient conditions.
Unfavourable ambient conditions are:
• Excessive dampness or humidity
• Dust or combustible gases, vapours or solvents
• Electrical storms or stormy conditions and strong electrostatic fields, etc.
For safety and approval purposes, you must not rebuild and/or modify this product. Using the
product for purposes other than those described above may damage the product. In addition,
improper use can cause hazards such as a short circuit, fire or electric shock. Read the
instructions carefully and store them in a safe place. Only make this product available to third
