• The number system (10, 16, 2 , 8 ) is set by pressing [ 2nd ] [ dhbo ] to display
the menu, making one of the items underlined followed [ ENTER ]. A
corresponding symbol - "d ", "h", "b", "o" appears on the display. (The
default setting is d : decimal base). See Example 39.
(Note) : The total range of numbers handled in this mode is 0, 1, 2, 3, 4, 5,
6, 7, 8, 9, A, B, C, D, E, F. If values not valid for the particular number
system are used, attach the corresponding designator (d, h, b, o),
or an error message will appear.
Binary base ( b ) : 0, 1
Octal base ( o ) : 0, 1, 2, 3, 4, 5, 6, 7
Decimal base ( d ) : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
