Engineering units provide the capability to display user-selected units instead of voltage. All signal information enters the
Dash 8Xe / Dash 8X
as voltage. However, converting the voltage unit to an alternative unit of measure may be desirable
in applications that measure current, pressure, strain, or any non-voltage unit.
This allows the
Dash 8Xe / Dash 8X
to be compatible with transducers and probes that can provide a voltage output to
the
Dash 8Xe / Dash 8X
. The relationship between the voltage and the engineering unit is assumed to be linear,
characterized by a slope and offset (y = mx + b).
The following is an example of entering engineering units into the
Dash 8Xe / Dash 8X
. For this example, we will assume
we are entering the engineering units for a current probe that provides a
10mV/A
voltage output to the
Dash 8Xe / Dash
8X
.
