CHANNEL 1 MULTIPLICATION FACTOR
Channel 1 was designed to count electric pulses from liquid flow
meters (litters per pulse, for example). The amount of liquid
corresponding to each pulse and the unit of flow can be easily
configured.
Although suited to flow measurements, channel 1 can measure any
variable whose signal is an electric pulse (energy, production
batches, etc). The user can define a new unit by typing it in the
corresponding text box. The expression
l/pulse
in the multiplication
factor is meaningless in this case, so please disregard it.
LOGCHART-II
INSTALLING LOGCHART-II
To install the LogChart II, execute the
LC_II_Setup.exe
program
available on our website. The installation wizard will then guide you
throughout the installation process.
RUNNING LOGCHART-II
Start the program. The main window will appear on the screen, as in
Fig. 3
.
Fig. 3
– LogChart-II main window
The LogChart II requires a communication port to talk to the logger.
Clicking on the menu
Port
, all free communication ports available in
the computer will be listed, including the USB port if the driver is
installed. Select one and connect the corresponding wand (IR-
LINK3/RS232 or IR-LINK3/USB) to it. The chosen port will be
remembered next times the LogChart II is initiated.
When the selected port is successfully opened, the LogChart II initial
screen is opened, enabling the buttons below:

OPTIC INTERFACE IR-LINK3
Configuring, monitoring or downloading data from the logger through
LogChart-II requires that the IR-LINK3 communication interface be
connected to your PC. This interface is sold separately.
The IR-LINK3 interface sends and receives data to/from the logger
through infrared signals. Windows will request the proper driver
installation, which is found on our website. After installation is
completed, the IR-LINK3 interface is recognized whenever it is
connected to the PC.
NOTE
: After the USB driver installation, the LogChart II must be
opened again. In the “Port” menu, choose the same port selected for
the optical interface communication (COM1, COM2 or USB).
CONFIGURING THE LOGGER
Make sure the IR-LINK3 wand is connected to the PC port selected.
The interface must be pointed towards the logger communication
window (see
Fig. 5
) at a distance of about 15 cm.

Click the
button to start the communication between the logger
and the software; the
Parameters Configuration
window is then
displayed (
Fig. 6
), showing the current configuration and information
about the logger. New configuration parameters defining the
operation mode for a new application can be entered. The fields of
the configuration window are described below.

GENERAL INFORMATION
General information on the top of the screen informs the model, serial
number, logger current date/time, PC date/time, firmware version
(logger model version), memory capacity and used memory.
The time is constantly updated in this screen, provided that the
logger and the PC are communicating.
ACQUISITIONS
Interval:
It determines the interval between readings in the hh:mm:ss
format. New data is stored in the logger memory after each time
interval.
External Battery Switch
time
:
Defines an interval of time preceding
each measurement for turning on the power supply of external
devices (4-20 mA transmitters, for example). This feature is intended
for saving power when the external power supply is battery powered
and the logging interval is long. This signal is disabled when a
measurement is completed.
This time is limited to 10 seconds and must be less than half of the
interval between readings.
When channel 2 (analog input) is configured to
Instantaneous
readings, the measurements are taken at the end of the defined
interval between readings. For
Average, Minimum
and
Maximum
readings, the logger executes 10 readings within this interval. This
must be taken into account when defining the time to active the
external power supply (1/2 of interval/10).
Estimated Time:
It informs the estimated time for the
accomplishment of programmed readings based on the logging
“
Interval
” and on the number of programmed readings.
Daily Repetition:
Allows loggings to be repeated every day, for
example, recording data from 8 AM to 5 PM day after day.
The start and stop times are defined in the fields “
Start time
” and
“
Stop time.
”
