1.Safety Information
Read the following safety information carefully before attempting to
operate or service the meter.
Use the meter only as specified in this manual:
•Environment conditions
Altitude lower than 2000 meters
Relatively humidity <:90%RH
Operation Ambient 0 to 4o•c
•Maintenance & Clearing
Repair or servicing not covered in this manualshould be performed
by qualified personnel.
Periodically wipe the case with a dry cloth. Do not use solvents or
eradicator on this instrument.

2.Functions Description
This Sound Level Data Logger is designed for noise project; quality
control; illness prevention and eure and all k.inds of environmental
sounds measurement. lt is applied to the sounds measurement at
factory; school; office; traffic access and household, etc.
•This unit confirms to the IEC61672-1 CLASS2 for Sound Level Meter.
• NORM (Normal) & PEAK mode
•Data manage: STORE, REAL TIME
•Over range indication
•A & C Weighting
• FAST & SLOW response
•Software Calibrate
•Manual & Automatiestartmode
Note:
•ln NORM mode, 20 data will be picked (one datum per 50ms) and
the average value of the 20 data will be stored. At the same time, a
PEAK MAX. & a PEAK MIN. will be picked wihtin all the sampling data.
tf sampling rate> 1Os, the periphery power will be off before reaching
sampling time to save battery energy.
•ln PEAK mode, Datalogger will always measure data with 50ms
spacing. PEAK value means the MAX. and MIN. reading in the whole
measurement but not the MAX. and MIN. in the sampling point. The
stored sampling value is the MAX.. in the sampling point af 20 sampling
data but not the average.
•STORE: Datalogger sampling data at sampling point and store it to
the datalogger memory
•REAL TIME: Datalogger sampling data at sampling point than send
it to PC by the USB immediately, and the PC software will display the
value

5.0perating lnstructions
•Setup the Datalogger by software before use it.
• Und er the Manual mode, press and hold the button for 2s, Datalogger
start to measure, and LED indicates the function at the same time.
( see LED Flash lndication for details.)
•Under the Automatie mode, the Datalogger start to measure after
setup in software, LED indicate the function at the same time.
(see LED Flash lndication for details.)
•Du ring measurement, the green LED indicates the working state by
flashing with the frequency setup in the software.
• When datalogger memory full, it will stop recording and yellow LED
will flash 1OS/time.
• Du ring measurement. when measured value exceeds the alarm range,
the red LED will flash. (2 times-high alarm, one time·low alarm}
•As the battery power is not sufficient, the red and green LED will
flash simultaneaus 1OS/time for indication.
•Datalogger data can be read time after time, the readings you are
checking are the real time measured ones.(1 to 129920 readings)
•Without battery, the latest 1.5 hours (the most) data will be lost.
Other data can be read in software after battery is installed.
•When replacing the battery, turn offthe meter and open the battery
cover. Then, replace the empty battery with a new 1/2AAA 3.6V
battery and go for the cover.
6.Notice
•Do not storeor operate theinstrumentat high temperature and high
humidity environment.
•When not in use for long time, please takeout the battery to avoid
battery liquid leakage and cautery on the instrument
•When using the instrument in the presence of the wind, it is a must
to mount the windscreen to not pick up undesired signals.
•Keep microphone dry and avoid severe vibration
•Without battery, the latest 1.5 hours (the most) data will be lost.
•You have to setup the Datalogger by software before use it.

NORM Mode: Sound MAXISound MIN means the MAX degree or MIN
degree of the sampling data. lt is the average value of
the 20 sampling data. PEAK MAXIPEAK MIN means the
MAX or MIN degree of all the measuring values.(not the
average value)
PEAK Mode: Sound MAXISound MIN means the MAX degree or MIN
degree of the 20 sampling data.
PEAK MAXIPEAK MIN means the MAX or MIN degree of all the
measuring values.
The yellow line show the datalogger is low battery.

B.Battery Replacement
When the battery is low power you should replace the battery.
Datalogger does not lose its stored readings when the battery is
discharged orwhen the battery is replaced; the data logging process
will however be stopped and cannot be re-started until the battery
has been replaced and the logged data has been downloaded to PC.
Only use 3.6V Iithium batteries. Before replacing the battery, remove
the model from the PC.
LhwARNING:
Handle Iithium batteries carefully, observe wamings on battery casing.
Dispose of in accordance with local regulations.
