1-10 Getting Started 2400 Series SourceMeter
®
User’s Manual
The power cord supplied with the SourceMeter 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.
3. Turn on the instrument by pressing the front panel power switch to the on
(1) position.
Power-up sequence
On power-up, the SourceMeter performs self-tests on its EPROM and RAM and
momentarily lights all segments and annunciators. If a failure is detected, the
instrument momentarily displays an error message, and the ERR annunciator
turns on (error messages are listed in Appendix B).
NOTE For the Model 2430, there is an internal bank of capacitors that need to
charge. While charging, the message “Charging capacitor bank, please
wait” message will be displayed for approximately 10 seconds.
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 model number and the firmware revi-
sion levels are displayed. For example:
REV A01 A02
where: A01 is the main board ROM revision.
A02 is the display board ROM revision.
Also displayed is the line frequency. (If the wrong frequency is displayed, it can be
set manually as covered below). The communication interface status is briefly dis-
played. If the IEEE-488 bus is the presently selected interface, the identification
message will include the primary address. For example, if the primary address is
24 (factory default), the “IEEE Addr=24” message is displayed. If the RS-232
interface is selected, the “RS-232” message is displayed.
After the power-up sequence, the instrument goes to its normal display state with
the output off (OUTPUT indicator light off). With the output off, the “OFF” message
is displayed, and dashes replace the reading.
