1-8 Getting Started
Power-up
Line power connection
The power supply operates from a line voltage in the range of 100-120VAC/200-240VAC at
a frequency of 50 or 60Hz. Line voltage and frequency are automatically sensed, therefore there
are no switches to set. Check to see that the line power in your area is compatible. Use the
:SYSTem :LFRequency? query (Section 11) to read the line frequency.
Perform the following steps to connect the power supply to the line power and turn it on:
WARNING The po
wer cord supplied with the Model 2306 contains a separate ground for
use with grounded outlets. When proper connections are made, 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.
1. Before plugging in the power cord, make sure the front panel power switch is in the off
(0) positi
on.
2. Connect the female end of the supplied power cord to the AC receptacle on the rear
pane
l.
3. Turn on the power supply by pressing the front panel power switch to the on (1) position.
Power-up sequence
On power-up, the power supply performs self-tests on its RAM and EPROM. After a blinking
cursor appears on line one, RAM tests are completed. After a blinking cursor appears on line
two, EPROM self tests are completed.
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:
• T
op line — The model number and the IEEE-488 address are displayed. (The factory
default GPIB address is 16.)
• Bottom
line — Firmware revision levels are displayed for the main board and the display
board. Also displayed is the detected line frequency.
After displaying the above information, any errors that occurred during the startup sequence
will
be displayed. Then, the instrument goes to the default settings or the saved power up settings
(*RST or SAV0-4) display type with the output off (see “Default settings” on page 1-11). Any
missed error messages may be vie
wed over the bus using the :SYST:ERR? (see “Error Queue”
in Section 7).
NOTE F
or Models 2306-PJ and 2306-VS, the saved power up settings available are from
SAV0-SAV2.
