4. MEASURING PROCEDURE
1)Plug the " Output plug " of " AC/DC 9V adapter " to
" DC 9V power input socket ( 3-14, Fig. 1 ), plug the
" Input plug " of the " AC/DC 9V adapter " into a properly
AC outlet ( AC 100 V to 240 V ) following.
2)The " Display " ( 3-1, Fig. 1 ) will show both the
CO2, Humidity and Temperature value at the same
time. Up Display - Humidity value
Middle Displa
y
- Temperature value
Low Display - CO2 value
3)Backup batteries consideration :
It recommend to install the batteries DC 1.5 V battery
( UM4, AAA ) x 6 PCs into the " Battery compartment "
( 3-9, Fig. 1 ) for clock time base backup. If do not
install those batteries, the internal clock may can not run
properly after the meter is disconnect from the " AC/DC
9V adapter " for a certain period.
Remark :
* How to change the Temp. unit ( , ), refer to chapter 7-6,℃℉
page 15.
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 " ( 3-13, Fig. 1)
with the correct direction exactly.
* It recommend use memory card's capacity is 4 GB.≦
6
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.
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 SD card is not plugged
no into the meter.

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.
c.. 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 ",
otherwise some existing recent save
data may loss.
