Enable: If the “Enable” box at the top of a column is checked,
data for that channel will be shown in the historical record and
be available for export to Excel. The data
for all the analog channels is always being
recorded whether the channel is enabled
or not.
Units: This field shows the units that will
appear at the top of the data column for
that channel in the historical record as well
as the display of data in the main screen.
Click on the field to enter the unit or select
from a predefined list. Note that psi is not included in this list.
High EU: The High EU field is the engineering unit where the
highest output from the sensor is achieved during the calibration process, in this
case a pressure of 100 psi.
Low EU: The Low EU field is the engineering unit where the lowest output from the
sensor is achieved during the calibration process, in this case a pressure of zero.
High Raw: This is the raw data value as measured by the data logger that
corresponds to the High EU value and is automatically set by the calibration process.
In this case, the raw data value returned by the logger at a pressure of 100 psi.
Low Raw: This is the raw data value as measured by the logger that corresponds to
the Low EU value and is automatically set by the calibration process. In this case,
the raw data value returned by zero pressure.
Disp High: This field sets the upper limit of the bar graph displayed in the main
screen and provides a way of scaling the graph beyond the upper limit used to
calibrate the logger. In this example, the upper calibration point was a pressure of
100 psi but the maximum range of the sensor is 200 psi.
Disp Low: This field sets the lower limit of the bar graph displayed in the main
screen and provides a way of scaling the graph beyond the lower limit used to
calibrate the logger. In this example, the lower calibration point was at zero psi.
