Channels Field
By selecting the “Channels” option, the user is able to choose the individual settings for each input channel, as Fig. 7 shows
The Parameters are:
•
Tag
: Defines a name (up to 8 characters) for identifying the variable to be measured.
•
Input
: The signal applied to the logger input is defined here. The list shows all the input options available. The selected option must be
in accordance with the internal configuration of the jumper, as Table 1 shows.
•
Unit
: Defines the variable unit.
•
Offset
: Allows fine offset corrections on the measured value.
•
Value
: Defines readings recording mode. The following Options are available:
o
Instantaneous
: The instant value read at the logging time.
o
Average
: Ten readings at each reading interval. The average value of readings is the value recorded.
o
Minimum
: Ten readings at each reading interval. The lowest value found is recorded.
o
Maximum
: Ten readings at each reading interval. The highest value found is recorded.
•
Alarm
: defines a limit range of variables measured that, once exceeded, trigger the alarm. Once activated, the alarm LED indicator
stays so even after the alarm-triggering situation has ceased.
o
LOW
defines the minimum value under which the alarm is triggered.
o
HIGH
defines the maximum value above which the alarm sensor is triggered.
After filling all the fields, send the configuration to the logger by clicking on the button
New settings and PC current date/time are then sent to the logger.

Data Download and Visualization
The transference of data to a PC is accomplished by using the LogChart II software. Data can be collected anytime and saved in files for future
analysis (menu “File Save” or “File Save as”). Help can be accessed from the LogChart-II software when necessary.
Offloading data: data offload is accomplished by clicking on the button
Or using the LogChart -II menu. During data transfer, a status bar indicates remaining data to be transferred. Data downloading time is
proportional to the number of readings logged. At the end of data transference, the Graph window is displayed.
