Section 2: Getting started
IEEE-488 primary address
The IEEE-488 primary address of the instrument must be the same as the primary address you
specify in the controller's programming language. The default primary address of the instrument is 27,
but you can set the address to any value from 0 to 30 by using the MENU key.
Display
The display of the Model 6517B is primarily used to display readings along with the units and type of
measurement. When not displaying readings, it is used for informational messages, such as menu
headings and selections. At the top of the display are annunciators to indicate various states of
operation.
Exponent mode (Engineering or Scientific)
Readings on the display can be expressed in engineering units or in scientific notation, as shown in
the table below. In scientific mode, the exponent can be fixed to a specified value, or it can be
floating. In floating mode, the instrument automatically selects the exponent value.
All exponent mode selections are performed from the DISPLAY option of the GENERAL menu, which
is part of the MAIN MENU.
