MEASURING PROCEDURE

4-l fuund tevel meEr

l) Power on by pressing the " Power On/Off Button'( 3-2,

Fig. 1 ) , the mete/s default function ls " Auto range ",

" n ft"qr"n.y weighting " & " Fast time weighting "' The

LCD display will show the unit " A. Fast Auto ".

2) Select ' A ' or " C " frequency weighting by pressing the

" Ay'C Button " ( 3-6, Fig. 1 ) .

Note :

a. The characteistk table ofA, C weighting, please

rcf. page 22.

b. me characteristic of A weighting is simulated as

the " Human Ear Listenlng " resPonse.

Typically atways seM the A weighting when makes

environmental sound level measurement.

c. The C weighting dtaracteri$lc is near the " FUT "

t6ponse. Typically it is suibble for cltxking the

noise of nachinery ( Q.C. dreck ) & knowing the

rcal sund level of the tesftrd quipment

3) Determine proper rneasuring range by pressing the

" Range Button " ( 3-5, Fig' f ).

After power on the default range is " Auto range ".

In the same time the lower right display will show the text

of " Auto ".

Under the auto range, press the " Range Button " ( 3-5,

Fig. 1 ) onc steP bY step will enter

to the manual range ( range 1, range 2, range 3 ) and

auto range in sequence. There are still 3 manual ranges

for your choice :

* lvlanual range 1 , 30 - 80 dB range :

Display will show the unit of " 30 - 80 ".

* Manual range 2, 50 - 100 dB range :

Display will show the unit of " 50 - 100 ".

* Manual nnge 3 , 80 - 130 dB range :

Display will show the unit of " 80 - 130 ".

4) According to various measuring sound source, select the

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

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

Note :

a. If select the function of " Fast " time weighting, the

dbplay 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 Dab Hold

During the measurement, press the " Hold Button " ( 3-3,

Fig. 1 ) once will hold the measured value & the LCD will

display a' HOLD' symbol.

Press the " Hold Button " once again will release the data

hold function.

4-3 Dab Reed ( Max., Min. tadlng )

l)The data record function records the maximum and

minimum readings. Press the " REC Button " ( 3-4, Fig.

1 ) once to start the Data Record functlon and there

will be a " REC " symbol on the display.

2)With the " REC " symbol on the display :

a) Press the " REC Button " ( 3-4, Fig, 1 ) once, the

'REC MAX " symbol along with the maximum value

will appear on the display.

If intend to delete the maximum value, just press

the " Hold Button " ( 3-3, Fig, 1 ) once, the display

will show the " REC " symbol only & execute the

memory function continuously.

b)Press the " REC Button " ( 3-4, Fig. 1 ) again, the

" REC MIN " symbol along with the minimum value

will appear on the display.

If intend to delete the minimum value, Just press the

" Hold Button " ( 3-3, Fig. 1 ) once, the display wil

show the " REC " symbol only & execute the

memory function continuously.

c) To exit the memory record function, just press the

" REC " button > 2 seconds at least. The display will

reveft to the current reading.

4-4 LCD Racklight ON,/OFF

a, Insert the SD card

frenarg a " SD memory card ,,( 1 GB to 16 GB, optional ),

insert the SD card into the n SD card socket o ( 3-19, Fig. 1),

The front panel of the SD card should face against the -

the down case.

b. SD card Format

If SD card just the first time use into the meter, it

recommend to make the " SD card Format " at first, ,

please refer chapter 7-6 ( page 19 ).

5. DATALOGGER

c. Time setting

If the meter is used at first Ume, it should to adiust the

clock time exactly, please refer chapter 7-1 ( page 16 ),

d, Decimal format setting

The numerical data structure of SD card is

default used the " . " as the deiimal, for

example "20.6" '1000.53" . But in certain

countries ( Europe ...) is used the " , " as the

decimal point, for example " 20, 6 '

"1000,53'. Under such situation, it should

change the Decimal character at first, details

of setting the Decimal point, refer to Chapter

7-2, page L7,

* It recommend strongly, do not use memory cards that

have been formatted by other meter or other

installatlons ( such as camera,.. )

Reformat the memory card with your meter-

t It the SD mernory card exlst the trouble during

format by the meter, use the Computer to reformat

again, it can fix the Problem,
