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

Does not observe the warning and/or operation instruction, it’s

possible to damage the instrument either its components or the

․ 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.

CAUTION

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.

1. : The A weighting curve is based on 40 Phon Fletcher-Munson Equal Loudness
Contour, Noise assessment in human, suggest to use the A weighting.

2. The C weighting in essentially is approximate smooth. With labor safety concern,
suggest using the C weighting.

3. The Z weighting for the electric instrument interior not the linear signal which
processes after the filter, suits in wants to output AC or the DC signal does other
research to use.

The Z weighting is a linear signal which is not processed through the filter.

It’s suitable to output AC or DC signal for research.

6.1. GENERAL INFORMATION

This is a precision instrument. To guarantee its performance be sure to use it or keep it
stored on suitable environmental conditions. Do not expose it to high temperatures or
humidity or direct sunlight. Be sure to turn the power off after use. If you expect not
to use the instrument for a long period remove batteries to avoid leakages of
battery liquid which could damage the its inner components.

6.2. BATTERY REPLACEMENT

The low battery “ ” indication is displayed; the battery should be replaced.

 Turn off the instrument.
 Remove the battery cover.
 Remove all the batteries from the battery holder.
 Insert four new batteries of the same type respecting the polarity signs.
 Install the battery cover.
 Please follow the local laws and regulations to process the waste battery.

6.3. CLEANING

To clean the instruments use a soft dry cloth. Never use a wet cloth, solvents or wate.

6.4. END OF LIFE

Caution: this symbol indicates that equipment and its accessories shall be

subject to a separate collection and correct disposal.
