1. INSTRUMENT CARE

Do not attempt to remove the mesh cover from the microphone as this will cause

damage and affect the accuracy of the instrument.

Protect the instrument from impact. Do not drop it or subject it to rough handling.

Transport it in the supplied carrying case.

Protect the instrument from water, dust, extreme temperatures, high humidity and

direct sunlight during storage and use.

Protect the instrument from air with high salt or sulphur content, gases and stored

chemicals, as this may damage the delicate microphone and sensitive electronics.

Always turn the instrument off after use. Remove the batteries from the instrument

if it is not to be used for a long time. Do not leave exhausted batteries in the

instrument, as they may leak and cause damage.

Clean the instrument only by wiping it with a soft, dry cloth or, when necessary, with

a cloth lightly moistened with water. Do not use any solvents, alcohol or cleaning

agents.

2. FEATURES

The SLM 1353M Sound Level Meter complies with the requirements of

IEC 61672-1: 2003 standard for a Class 2 instrument.

The instrument contains several features which permit sound level measurements

under a variety of conditions.

Features include:

Ease of use.

Easy to read large display.

Five measurement ranges.

Fast, Slow and Impulse time weightings.

A and C frequency weightings.

Storage of up to 32000 measurement records.

USB serial port for downloading records to a computer or real time analysis to a

computer.

Both AC and DC signal outputs are available from a single standard 3.5mm

coaxial socket suitable for use with a frequency analyzer, level recorder, FFT

analyzer, graphic recorder, etc.

Leq, SEL, SPL MAX, SPLMIN, PH (Peak Hold), L05, L10, L50, L90, and L95, ten

measured parameters are monitored during measurement and can be viewed

selectively by pressing the button.

Preset measurement time up to 24 hours.

Sound level alarm output connector.
