Connector for RS-232 remote operation. Use a straight through (not
null modem) DB-9 cable such as a Keithley Model 7009-5.
OUTPUT ENABLE connector:
OUTPUT ENABLE
Connector for output enable operation. Male DB-9 connector for output
enable line and ground.
GPIB connector:

Connector for GPIB remote operation. Use a shielded cable
(Model 7007-1 or 7007-2).
Power-up
This section covers line power connection, line voltage settings, fuse replacement, and the power-
up sequence.
Line voltage selection
The Model 6482 operates from a line voltage in the range of 100 V, 120 V, 220 V, 240 V (±10
percent) at a frequency of 50 Hz or 60 Hz. Before plugging in the instrument, make sure the line
voltage setting visible through the small window in the power module (
) is correct for the
line voltage in your area.
CAUTION
Operating the instrument on an incorrect line voltage may cause damage,
possibly voiding the warranty.
If the voltage setting is not correct, change it as described in
Line power connection
Perform the following steps to connect the Model 6482 to line power and turn it on:
1. Before plugging in the power cord, make sure the front-panel power switch is in the off (0)
position.
2. Connect the female end of the supplied power cord to the AC receptacle on the rear panel.
WARNING
The power cord supplied with the Model 6482 contains a separate ground for
use with grounded outlets. When proper connections are made, the
instrument chassis is connected to power line ground through the ground
wire in the power cord. Failure to use a grounded outlet may result in personal
injury or death due to electric shock.
3. Turn on the instrument by pressing the front-panel power switch to the on (1) position.
Power-up sequence
When the Model 6482 is turned on, it performs self-tests on its EPROM and RAM and
momentarily lights all segments and indicators. If a failure is detected, the instrument momentarily
displays an error message, and the ERR indicator turns on. Error messages are listed in
.
NOTE
If a problem develops while the instrument is under warranty, return it to Keithley
Instruments for repair.
If the instrument passes the self-tests, the firmware revision levels are displayed. For example:
