4. MEASURING PROCEDURE
1)Install the batteries into the battery compartment :
* Loose the " Screw of the battery cover " ( 3-9, Fig. 1 )
and take away the " Battery Cover " ( 3-8, Fig. 1 ) from
the meter.
* Replace with DC 1.5 V battery ( UM4/AAA, Alkaline/Heavy
duty type ) x 6 PCs, and reinstate the cover.
* Make sure the battery cover is secured after changing
the battery.
2)Insert the plug of " Temp. probe " ( For example the
included Temp. probe, TP-01 " into the " T1 Temp.
probe input socket " ( 3-10, Fig. 1 ).
If you have other Temp. probes, then plug its plug to
" T2 Temp. probe input socket " ( 3-11, Fig. 1 ) or
" T3 Temp. probe input socket " ( 3-12, Fig. 1 ).
Remark :
* If plug one Temp. probe to the meter, will show
the one channel ( T1 ) Temp. only.
* If plug two Temp. probes to the meter, will show
the two channels Temp. ( T1, T2 ).
* If plug three Temp. probes to the meter, will show
total three channels Temp. ( T1, T2, T3 ).
3)The " Display " ( 3-1, Fig. 1 ) will show the
temperature value ( T1, T2, T3 ) that sensing from Temp.
probe.
Remark
:
*
T
he up Display value will present the T1 temperature value.
*
T
he middle Display value will present the T2 temperature value.
*
T
he low Display value will present the T3 temperature value.

5. DATALOGGER
5-1 Preparation before execute datalogger function
a. Insert the SD card
Prepare a " SD memory card " ( 1 GB to 16 GB, optional ),
insert the SD card into the " SD card socket " ( 3-16, Fig. 1)
with the correct direction exactly.
* It recommend use memory card's capacity is 4 GB.≦
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 7-1 ( page 12 ).
* It recommend strongly, do not use memory cards
that have been formatted by other meter or by
other installation ( such as camera... ). Reformat
the memory card with your meter.
* If the SD memory card exist the trouble during
format by the meter, use the Computer to
reformat again can fix the problem.
c. Time setting
If the meter is used at first time, it should to adjust the
clock time exactly, please refer chapter 7-2 ( page 12 ).
d. Decimal format setting
The numerical data structure of SD card is
default used the " . " as the decimal, 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
7-5, page 14. 6

e. 3 Information of LCD display
* If the Display show :
It means that the SD card exist the problem
CH- or the SD card memory is full, it should
CArd change SD memory card.
* If the Display show :
It means that the battery is low voltage.
LobAt Under such condition, the Datalogger
function is disable.
* If the Display show :
It means that the SD card is not plugged
no into the meter.
CArd
5-2 Datalogger
a. Start the datalogger
Press the " Logger button ( 3-2, Fig. 1 ) > 2 seconds
continuously, until the Display show the indicator "
DATALOGGER ", release the " Logger Button " ( 3-2, Fig.
1 ), then the measuring data along the time information
will be saved into the memory circuit.

Remark :
*
How to set the sampling time, refer to Chapter 7-3,
page 13.
*
How to set the beeper sound is enable, refer to
Chapter 7-4, page 13.
b. Finish the Datalogger
During execute the Datalogger function ( Display show the
" Datalogger " indicator ), press the " Logger button " ( 3-2,
Fig. 1 ) > 2 seconds continuously, until the Display
indicator " DATALOGGER " is disappeared, release the
" Logger Button " will finish the Datalogger function.
Before take away the SD card from the
meter, it should execute the
procedures of " Finish the Datalogger ",
( It should wait for the Display counter to count
down to zero value. )
otherwise some existing recent save
data may loss.
5-3 Check time information
Press " Time button " ( 3-3, Fig. 1 ) > 2 seconds
continuously, the LCD display will present the time
information of Year/Month/Date, Hour/Minute/Second and
the sampling value.
