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:

ˆ

  Ease of use.

ˆ

  Easy to read large display.

ˆ

  Five measurement ranges.

ˆ

  Fast and Slow time weightings.

ˆ

  A and C frequency weightings.

ˆ

  Storage of up to 32000 measurement records.

ˆ

  RS-232 serial port for downloading records to a computer or real time analysis to a

computer.

ˆ

  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.

3. MEASUREMENT PARAMETERS

The following parameters are used on the instrument.

ˆ

 A 

 “A” frequency weighting sound pressure level

ˆ

  C

 “C” frequency weighting sound pressure level

ˆ

 FAST

Fast time weighting

ˆ

 SLOW

Slow time weighting

ˆ

 SPL 

 Current time-weighted sound pressure level

ˆ

 SPL 

MAX 

 Maximum time-weighted sound pressure level

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