8.5 Units Preferences

Unit Preferences allows you to see, manage and create the units used by the equations. Each

unit has a description, a base subunit and possibly several other subunits. For example, the

unit DC current has Amps as its base subunit and milliamps and microamps as other subunits.

The base subunit is listed first. Each subunit has a description, symbol, and a scale and

offset. The scale and offset are used to convert values from the base subunit to other

subunits.

Note that you cannot edit, delete, or remove factory units and subunits. Also, if you need to

use a special character, such as "

°" for degrees,

for the symbol, click on the Map of

Characters in the Subunit form to pop the standard character map. From the character map,

you can copy the symbol and paste it into the Subunit form. Note that not all symbols can be

displayed on the graph.
