10. UNKNOWN Terminals

These connectors let you connect the instrument with a device under test (DUT) via test
accessories (such as an adapter, test fixture, or cable). These accessories adopt a
four-terminal pair design, thereby enabling more accurate and wider-range dynamic
measurements. Each test connector has a pair of holes for securing the test accessory to the
instrument.
INSTALLATION CATEGORY I
CAUTION To prevent failure, do not apply dc voltage or current to the UNKNOWN terminal. Special
care must be taken with capacitors since they may be charged. Be sure to connect the DUT
to the UNKNOWN terminal (or test fixture) only after discharging them sufficiently.

11. Built-in 3.5 Inch Floppy Disk Drive

Allows you to store and retrieve such data as measurement data, instrument settings, screen
contents, and HP Instrument BASIC programs. This drive uses a 3.5-inch, MS-DOS format
floppy disk of 1.44 MB capacity.
