Operating Instructions

Function selection

1) Turn on the meter by pressing the Power Button. To turn the meter

off, hold the Power Button for over 2 seconds. The meter’s function

defaults are set to “Auto Range, “A Frequency Weighting”, and Fast

Time Weighting”. The screen will display “A. Fast Auto”.

2) Switch between “A” or “C” Frequency Weighting by pressing the

“A/C Button”.

3) Determine proper measuring range by pressing the Range Button.

Press the Range Button to scroll through the Four range types.

There are three manual ranges (range 1, range 2, range 3) and auto

range in this sequence:

Manual range 1, 30 - 80 dB range: Display will show the units “30 - 80”

Manual range 2, 50 - 100 dB range: Display will show the units “50 - 100”

Manual range 3, 80 - 130 dB range: Display will show the units “80 - 130”

4) Select the Time Weighting (Fast or Slow) by pressing the Time

Weighting Button. The screen will display either “FAST” or “SLOW”,

depending on your selection.

Data Hold

While taking a measurement, press the Hold Button once and the mea-

sured value will hold on the screen, and a HOLD symbol will appear.

Press the Hold Button once again will release the data hold function.

Data Record (Max., Min. reading)

The data record function records the maximum and minimum readings.

Press the REC Button once to start the Data Record function and a “REC”

symbol will appear on the display. With the “REC” symbol on the display:

1) Press the REC Button once, and a ”REC. MAX.” symbol along with

the maximum value will appear on the display. To delete the maxi-

with the minimum value will appear on the display. To delete the

minimum value, press the Hold Button once, and the display will

show a “REC.” symbol only and execute the memory function

continuously.

3) To exit the memory record function, press the REC button for 2

seconds. The display will revert to the current reading.

Backlight ON/OFF

After powering the meter ON, the LCD Backlight will turn on automati-

cally. While taking measurements, press the Backlight Button and the LCD

Backlight will turn off. Press the Backlight Button once again to turn the

LCD Backlight back ON.

Datalogger

Preparation Before Executing the Datalogger Function:

1) Insert the optional SD card into the SD card socket.

2) Before you use an SD card with this meter for the rst time, it is

recommend to format the SD card. See Advanced Settings section

of this manual for instructions.

3) If this is the rst time the meter is used you need to adjust the

clock. See Advanced Settings section of this manual for instruc-

tions.

4) Now you need to set the decimal format. The numerical data struc-

ture downloaded to the SD card is defaulted used the “.” as the

decimal, for example “20.6” “1000.53”. But in certain countries the

“,” is used as the decimal point, for example “20, 6” “1000,53”. See

Advanced Settings section of this manual for instructions on how

to change the Decimal Character.

Auto Datalogger (Set sampling time ≥1 second)

1) Start Datalogging; press the REC Button, and the “REC” symbol

will appear on the LCD screen, then press the Logger Button, the

“REC” symbol will ash while the measuring data and time informa-

tion is being saved in memory. To set the sampling time, and to

toggle the beeper sound on or off, refer to the Advanced Settings

section of this manual.

2) Pause the Datalogging; while Datalogging, if press the Logger But-

ton once. While paused, the “REC” symbol will stop ashing. Press

the Logger Button again to resume Datalogging, and the “REC”

symbol will begin to ash again.

3) Stop Datalogging; while the Datalogger function is paused, press

the REC Button for 2 seconds. The “REC” symbol will disappear

indicating the Datalogging function has stopped.

Manual Datalogger (Set sampling time = 0 seconds)

1) Set sampling time is to 0 second; Press the REC Button, and the

“REC” symbol will appear on the LCD screen. Press the Logger

Button, and the “REC” symbol will ash once and one Beep will

sound, at the same time the measuring data along the time infor-

mation will be saved in memory. The lower Display will show the

Position (record) number, which is saved as well.

2) To Change the Position Number; press the Down Button and the

lower position number will ash on the display. Press the Up or

Down Buttons to set the Position Number (1 to 99) to help identify

the measurement location. The lower Display will show P x (x = 1 to

99). After the position number is selected, press the Enter Button to

Checking the Time

During normal functions (not Datalogging), press the Time Check Button

and the lower LCD display will show the Year, Month/Date, Hour/Minute.

Check Sampling Time Information

During normal functions (not Datalogging), press the Sampling Button and

the lower LCD display will show the Sampling Time Information.

SD Card Data Structure

1) The rst time the SD card is used in the meter, the SD card will

generate a folder: SLA01

2) The rst time you use the Datalogger, in the folder SLA01, a new

le name SLA01001.XLS will be created. The Datalogger will use

this le until the Data has reached to 30,000 rows. The meter will

then will generate a new le with a subsequent number, for ex-

ample SLA01002.XLS.

3) The folder SLA01 can hold 99.XLS les. When that number has

been reached, the meter will then will generate a new folder with

a subsequent number, for example SLA02. Max number of SLA--

folders is 10.
