Characteristics of A & C.
A weighting:
This characteristic is simulating the "Human
Ear Listening" response. Typically, when
making ambient or environmental sound
level measurements, always select A
weighting.
C weighting:
This characteristic is near the "FLAT"
response. Typically, it is suitable for
checking the noise of machinery (Q.C.
check) & knowing the sound pressure level
of the tested equipment.
Time Fast - t = 125 ms
weighting *"Fast" range is simulating the human ear
(Fast & Slow) response time weighting.

4. MEASURING PROCEDURE
4-1 Sound Pressure Measurements (SPL)
In SPL mode the display shows readings of
the sound pressure level.
b. The characteristic of A weighting is simulated as
the " Human Ear Listening " response.
Typically always select the A weighting module when
1) Power ON the meter by pressing and holding the ▼ Button
( 3-7, Fig. 1 ) for at least 2 seconds,
the display will show the Symbol "xx.x dB ,A, FAST ,Auto".
2) Frequency weighting select
To select the frequency weighting ( A or C), press the
▼Button ( 3-7, Fig. 1 ) once to change weighting ( A or C).
Note :
a. The characteristic of A weighting is simulated as the
" Human Ear Listening " response.
Typically always select the A weighting when makes
environmental sound level measurement.
makes environmental sound level measurement.
b. The C weighting characteristic is near the " FLAT "
c. The C weighting characteristic is near the " FLAT "
response. Typically it is suitable for checking the
response. Typically it is suitable for checking the
noise of machinery ( Q.C. check ) & knowing the
noise of machinery ( Q.C. check ) & knowing the
real sound level of the tested equipment.
3) According to various measuring sound source, How select the
Time Weighting ( Fast or Slow ) by press ▲ Button
( 3-6 , Fig. 1 ) to change Time Weighting ( Fast or Slow ) .
Note :
a. If select the function of " Fast " time weighting, the display
will show the unit of " FAST".
b. If select the function of " Slow " time weighting, the display
will show the unit of " SLOW ".
