Model 2308 Portable Device Battery/Charger Simulator User’s Manual
Section 1: 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 60 Hz, 165 V AC. 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 (see
Section 10
) to read the line frequency.
Perform the following steps to connect the power supply to the 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.
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.
After displaying the above information, any errors that occurred during the startup sequence will be
displayed. Then, the instrument goes to the default settings (*RST) or saved power-up settings
(SAV0-3) with the output off (see
Default settings
). Any missed error messages may be viewed
over the bus using the
:SYST:ERR?
command (see
Error queue
).
NOTE
See complete Specifications at
www.keithley.com
for the operating environment
requirements of the equipment before power-up.
WARNING
The power cord supplied with the Model 2308 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.
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 following information is briefly
displayed:
•
Top 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.
