Install the supplied Windows PC
Datalogger Software by placing the supplied program disk in the PC CD-ROM
drive. If the installation program does
not automatically open and provide on-screen prompts, double click the
SETUP.EXE file included on the program
disk. Follow the on-screen prompts to complete the installation. Before
running the Datalogger software please
connect the Logger to the PC and install the USB Driver software as
described in the next section.
Plug the Logger into an available USB port on the
PC. If this is the 1st time that the Logger is connected to
the
particular port on the PC, the following screen
will appear:
Select the ‘recommended’ installation (make sure
the program disk is still in the PC CD-ROM drive) and follow the
on-screen prompts to complete the driver
installation. If this is a repeat connect of the Logger to the USB port, the
driver installation process will be automatically
skipped.
3. RUNNING THE DATALOGGER SOFTWARE
With the Logger connected to the PC, Double click
the Datalogger Graph icon to launch the program. The main
software screen will appear with the MENU BAR icons
described as below.
Notes: When the Logger is
connected to the USB port, the battery inside the Data Logger is discharged at
a higher rate than normal. To conserve battery life, do not leave the Logger connected
to the USB port for a prolonged period of time
From
left to right the MENU BAR icons represent DATA DOWNLOAD, LOGGER SETUP, FILE
OPEN, FILE SAVE-AS, FILE PRINT, VIEW ALL, and ZOOM. In addition, the FILE,
VIEW, LINK, and HELP pull-down menus are available here. All will be discribed
in the following paragraphs.
①
LOGGER
SETUP
Click
on the computer icon on the menu bar (2nd from left) or select
LOGGER SET from the LINK pull-down menu. The Setup window will appear as shown below;
descriptions for each field in the Setup window are listed directly below the
illustration:
§
The CURRENT TIME field will
automatically synchronize with the PC date and time setting
§
The MANUAL and INSTANT
select buttons allow the user to start data logging immediately when the Setup
window is exited (INSTANT) or at a later time (MANUAL).
§
The LOGGER NAME field
allows the user to select a unique name for the logger
§
The SAMPLE POINTS field
instructs the logger to take a finite number of readings
§
The SAMPLE RATE pull-down
menu instructs the logger to log readings at a specific rate
§
The LED Flash Cycle can be
set by the user (the longer the time, the longer the battery life)
§
The ALARM SETTINGS portion
of the SETUP window allows the user to set HIGH and LOW temperature limits and disable
the flashing of the Logger’s LEDs thereby conserving battery energy
Click on the SETUP button to save
changes. Press the DEFAULT button to set the Logger to factory default
condition. Press the CANCEL button to abort the setup.
Notes: Any stored data will be
permanently erased when Setup is finished. To enable you to save this data
before it is lost, click Cancel and then you need to download data.
The battery will in all likelihood run out before logger will have
finished specified sample points. Always ensure that the remaining charge in
the battery is sufficient to last the complete duration of your logging
exercise. If in doubt, we recommend that you always install a fresh battery
before logging critical data.
If
INSTANT was selected in the SETUP window, the Logger begins logging at the
instant the SETUP button is pressed. If MANUAL was selected, the Logger must be
manually started by pressing and holding the Logger’s yellow button for approx.
3 seconds or until the two LEDs on the Logger flash at the same time.
Logging
will continue at the programmed sample rate until the number of readings
(sample points) specified in the Setup window is reached.
The
green LED flashes once per sample point and the red or yellow LED flashes when
user programmed alarm limits are exceeded. For details, see LED status guide.

DATA DOWNLOAD
To
transfer the readings stored in the Logger to the PC:
A.
Connect the Logger to the
same USB port used when the Logger was initialized
B.
Open the Datalogger
software program if it is not still running
C.
Click the Download icon (1st
on the left) or select Data Download from the LINK pull-down menu
D.
The Window shown below will
appear. Press DOWNLOAD to begin transferring readings
If
readings are successfully transferred, the VIEW screen and the SAVE screen (both
shown below) will appear.
In
the SAVE screen, name the file and save it to a convenient location. At a later
time, the user can select SAVE-AS and save the data as an Excel, Text, or
Bitmap file (explained in next section), however, the data in this case is
saved as an .rec file for use in this program only.
In
the VIEW screen (below) press VIEW to see the data graphically. If there are no
readings currently stored in the Logger, the program will let the user know via
warning screen.
When
VIEW is pressed, the Data Graph window appears
The
Data Graph window presents the transferred data in x-y graph format with
Date/Time represented on the horizontal axis and Temperature / Alarm Limits represented
on the y axis:
To
zoom in and zoom out data regions, there are several approaches, these are:
1)
Use the mouse to click and
drag a box around any data area to magnify the area selected.
2)
Click on the zoom magnifier
icon tool on the menu bar
3)
Select VIEW ALL or ZOOM OUT
from the VIEW pull-down menu.
In the example graph above, the
Temperature is represented by the solid red line (the lines are known as
‘traces’). The low and high alarm values for temperature are represented by the
dashed red trace.
To customize the graph window select SHOW
TRACES, BACKGROUND, GRID LINES, and MASK POINTS from the VIEW pull-down menu.
These options provide the following features:
SHOW TRACES: Allows the user to select
which data to view as a trace (Temperature & Alarms).
BACKGROUND: Select background color
scheme.
GRID LINES: Add or remove grid lines
from x and y axes.
MASK POINTS: Places dots on the traces
for the actual data points, breaking up the continuous nature of a trace.
③
FILE OPEN, FILE SAVE-AS
To save the transferred data in a
format other than the proprietary .rec format, click the SAVE AS icon from the
menu bar (4th from right) or select SAVE AS from the FILE pull-down
menu. The data can be saved in the following formats:
TEXT FILE (.txt)
EXCEL FILE (.xls)
BITMAP FILE (.bmp)
To open an existing data file for
viewing on the data graph window, click on the FILE OPEN icon on the menu bar (3rd
from left) or select FILE OPEN from the FILE pull-down menu. When prompted,
select a .rec file saved earlier.
④ FILE PRINT
To print a data graph window to a line
or network printer, click on the printer icon or select PRINT from the FILE
pull-down menu. Note that color graph windows can be accurately printed on
color printers.
Note : The
Logger retains data in its internal memory until the user begins a new logging
session. Starting a new logging session clears all of the logger’s stored
readings; be sure to save data before starting a new logging session.
