9 Convert Key Unit Conversions and Second FunctionsThe key is used to convert between measurement units or toaccess the second functions listed below: xClear All Clears all values, including all permanent entries to default values(except Preference Settings which are retained).Note: Use only when necessary, as it resets all stored values tofactory defaults. See page 82for a listing of default values. %x2 Squares the value in the display. For example,to square the value 10, enter 1 0then %. BSquare Root Function () Used to find thesquare root of a non-dimensional or area value( , 1 0 0 B =10). /x10y Allows entry of an exponent.

10 For example,8 / 1 4is 8 times 10 to the 14th power. 1/x Finds the reciprocal of a number ( , 8 = ).
