Frequency Characteristics of A & C.
Weighting
Network A weighting :
The characteristic is simulated as "Human
Ear Listing" response. Typical, if making
the environmental sound level
measurement, always select to A
weighting.
C weighting
The characteristic is near the "FLAT"
response. Typical, 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 simulated the human ear
(Fast & Slow) response time weighting.
Slow - t = 1 s
* "Slow" range is easy to get the average
values of vibration sound level.
Data hold To freeze the measurement value.

4. MEASURING PROCEDURE
4-1 Sound Pressure Level Measurements (SPL)
In SPL mode the display shows readings of
the sound pressure level.
1) Power ON the meter by pressing and holding the " Power
Button " ( 3-2, Fig. 1 )for at least 1.5 seconds,
the meter's default function is " A"( frequency weighting) ,
" Fast"( time weighting) " Auto range ". The
LCD display will show the Symbol " A, FAST , xx.x dB , 0 ".
2) Frequency weighting select
How to select the frequency weighting ( A or C), the
procedures please refer to chapter 7-7 page 20 .
Note :
a. The characteristic table of A,C weighting, please

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, select the

Button " ( 3-7 , Fig. 1 ).
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 ".
