The Data Ranges screen for voltage inputs has several user editable fields which
are used for linear scaling of a voltage input to the desired engineering units for
display.

1. Engineering Units
The three drop downs allow selection of various engineering units for
display depending on the type parameter being measured.
2. Input Range
The input range drop down shows the full measureable input of the data
logger. For voltage inputs there are seven ranges available. In addition
a custom input range can be assigned as a subset of any of the standard
ranges. This allows easier scaling of transducer output that is a subset of the
standard ranges to the display range.
3. Display Range
The display range boxes show the full range in engineering units for the
voltage input being configured. The graph range can be any subset of this
range.
4. Zero Adjust
The zero adjust provides a user configurable offset adjustment, in
engineering units, which will be applied to measurements across the full
range of input.
5. Moving Average Filter
This setting provides the option to average an individual channels input
samples.
6. Graph Range
The graph range is the y-axis range that will be shown on the waveform
view of the data logger. This can be any subset of the display range and
is defined in the assigned engineering units. It can also be adjusted on the
waveform view.
7. Decimal Places
Selects the number of decimal place to display.
Example: In this channel configuration, 0 to 5V input corresponds to 0 to 100 PSI.
Engineering Unit = PSI
Input Range = -5V to +5V
Custom Input Range = 0 to +5V
Display Range = 0 to 100
Graph Range = 3 to 15
