1. SAFETY PRECAUTIONS
When taking measurements:
․ Avoid doing measurements in humid or wet places - make sure that humidity is
within the limits indicated in section “environmental conditions”.
․ Avoid doing measurements in presence of explosive gas, combustible gas,
steam or excessive dust.
The following symbols are used:
Caution: refer to the user’s manual. An incorrect use may damage the
tester or its components
The instrument conforms to the CE standard
1.1. Preliminary Description
The ST-130/ST-130s is designed to test noise exposure in accordance with
OSHA,MSHA,DOS,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.
The SLM mode has a datalogging feature that can record up to 1000K readings
which can be downloand to PC for analysis.
The built-in USB interface to connect PC.
Applications: Evaluation of environmental noise, Measurements of noise at
workplaces, Assessment of product noise.
1.2. Note
CAUTION
Does not observe the warning and/or operation instruction, it’s
possible to damage the instrument either its components or the
operator
․ Do not operate the instrument at temperature and humidity environment
beyond to reference conditions of chapter 7.2.1.
․ Keep the microphone dry and avoid severe vibration.
․ Wind blowing across the microphone would bring additional extraneous
noise. Once using the instrument in the presence of wind, it must mount the
windscreen to prevent the undesirable signals.

2. PREPARATION FOR USE
2.1. Initial
The instrument has been checked mechanically and electrically prior to shipment.
Take care to ensure the instrument reaches you undamaged.
However, it is wise to carry out a rapid check in order to detect any possible
damage that may cause during transport.
If it’s damage, claims to the dealer immediately.
Check the packaging content according to packing list reported in 7.3.1 chapter .In
case of discrepancies, contact the dealer immediately.
In the event of re-shipment of the instrument please follow the instructions reported
in chapter 7.3.1.
2.2. Calibration
The instrument complies with the technical specifications contained in this manual
and such compliance is guaranteed for 1 year. The instrument is maybe need
recalibration after one year.
2.3. Storage
After a period of storage in extreme environmental conditions exceeding the limits
mentioned in paragraph 7.2.1 let the instrument return to normal measuring
conditions before using it.
