Getting Started 1-7
WARNING
The power cord supplied with the power supply contains a separate ground
for use with grounded outlets. When proper connections are made, instru-
ment 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 in-
jury or death due to electric shock.
3.
Turn on the power supply by pressing the front panel power switch to the on (1) position.
Fuse replacement
A rear panel fuse protects the power line input of the power supply. If the line fuse needs to
be replaced, perform the following steps:
1.
The fuse is located in a drawer below the AC receptacle (see Figure 1-1B). At the top of the
fuse drawer is a small tab. At this location, use a thin-bladed knife or screwdriver to pry the
fuse drawer open.
2.
Slide the fuse drawer out to gain access to the fuse. Note that the fuse drawer does not pull
all the way out of the power module.
3.
Snap the fuse out of the drawer and replace it with the same type (250V, 2.0A, 5

20mm
time lag). The Keithley part number is FU-81.
CAUTION
For continued protection against fire or instrument damage, only replace
the fuse with the type and rating listed. If the instrument repeatedly blows
fuses, locate and correct the cause of the problem before replacing the fuse.
4.
Push the fuse drawer back into the power module.
Power-up sequence
On power-up, the power supply performs self-tests on its EPROM and RAM.
NOTE
If a problem develops while the instrument is under warranty, return it to Keithley
Instruments Inc., for repair.
If the instrument passes the self-tests, the following information is briefly displayed:
•
Top line
— The model number and the IEEE-488 address are displayed. At the
factory, the address is set to 16.
•
Bottom line
— Firmware revision levels are displayed for the main board and the dis-
play board. Also displayed is the detected line frequency.
After the power-up sequence, the instrument goes to the presently saved display type with the
output off (see “Default settings”).
