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.

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

makes environmental sound level measurement.

c. The C weighting characteristic is near the " FLAT "

response. Typically it is suitable for checking 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

Time Weighting ( Fast or Slow ) by pressing " ENTER

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 ".

4-2 Running the Dose Meter Noise Survey

1) In " SPL" mode to select the " Dose " mode by

pressing and holding the" RUN button" ( 3-4 Fig 1 )

into the DOSE mode .

2) In "DOSE" mode, display will show DUR(duration) ,

0.00(cumulative dose) , 00 : 00 :00(current time) ,

0(record sampling time counter) , %DOSE(Dose mode) ,

FAST(Time weighting).

3) In Dose mode , Pressing and holding the " Time Button "

into setting , SET" DATE→SP-T→POFF→BEEP→DEC

→SD-F→A→Crit→Thr→ER→CLRM→DATE".

Note :

a:Crit(Criterion Level) : 80、84、85、87、90dB.

b:Thr(Threshold Level) : 70 to 90dB in 1 dB steps.

c:ER(Exchange Rate) : 3, 4, 5, or 6 db.

d:pressing the " Power Button" to leave the set mode.

e:Factory default settings : Crit→90 , Thr→70 , ER→3.

4) According to various measuring sound source, select the

Time Weighting ( Fast or Slow ) by pressing the "ENTER

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

5) In DOSE mode , pressing and holding the ▼button ,

display is shown and DUR , xx : xx : xx(h : m : s) ,
