Unit

Name of the engineering unit; for example, kilograms, volts, furlongs, or amps.

Direction

Direction of the conversion between raw and engineering units.

Conversion

Type of the selected conversion function. The frame to the far right will change to present the value to fill in for the selected conversion function type.

Table w/Interpolation

Conversion is specified by a lookup table. Results for input values that come between values in the first column are calculated via linear interpolation of values in the second column. Up to twenty pairs of values may be specified.

Table w/o Interpolation

Conversion is specified by a lookup table. Results for input values that come between values in the first column are calculated by selecting the value in the second column corresponding to the next lower value in the first column. That is, lookup is done without doing interpolation. Up to twenty pairs of values may be specified.
