Power switch

 – Turn on the 2750 by

pressing to the on (I) position. To
turn off, release the switch to the off
(O) position.

Window

 shows

line voltage setting

Using the 

supplied line cord

, connect to a grounded

AC power outlet. The line voltage setting shown in
the window of the fuse holder must match line the
voltage at the AC power outlet.

Five slots

 for Keithley

switching modules

For 

GPIB communication

, connect

to GPIB port of computer using an
IEEE-488 cable (Keithley 7007).

Communications configuration:

GPIB

 – Press SHIFT and then EXIT (GPIB) to

access menu. Use the edit keys to enable
(ON) the GPIB and set the address (ADDR).

RS-232

 – Press SHIFT and then ENTER

(RS-232) to access menu. Use the edit
keys to enable (ON) RS-232, and set the
terminator (TX TERM), FLOW control,
and BAUD rate.

For 

RS-232 communication

, connect

to serial port of computer using a
straight-through RS-232 cable (DB-9).
Do not use a null modem cable.
