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.

Dash 8Xe / Dash 8X Amplifier Channel Settings (Analog Channel Setup) Window

ACTION

User Unit Setup – Waveform 1 window. The Enable User Units

icon should be checked.

Select the Engineering Units box under the Enable User Units

icon. A keypad will appear. Erase the unit Volts and enter AMPS.
