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 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 200M measurement records (microSD CARD 4GB).  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.

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

L95, eleven measured parameters are monitored during measurement and can be viewed selectively by pressing the

Leq SEL SPL

button.

 Sound level alarm output connector.

3. MEASUREMENT PARAMETERS

The following parameters are used on the instrument.

 A → “A” frequency weighting sound pressure level  C → “C” frequency weighting sound pressure level  FAST → Fast time weighting  SLOW → Slow time weighting  IMP → Impulse time weighting  SPL → Current time-weighted sound pressure level  Leq → Equivalent continuous sound level  SEL → Sound exposure level  SPL MAX → Maximum sound pressure level  SPL MIN → Minimum sound pressure level  PH → Peak Hold sound pressure level  L:05 → 5% percentile sound level  L:10 → 10% percentile sound level  L:50 → 50% percentile sound level  L:90 → 90% percentile sound level  L:95 → 95% percentile sound level  SPL “MAX” → Maximum time-weighted sound pressure level (MAX symbol blink)

The various settings depend on the condition the instrument was in before it was last turned off.
