System-Related Operations
This section gives information on system-related topics such as storing power
supply states, reading errors, running a self-test, displaying messages on the
front panel, and reading firmware revisions.
State Storage
The power supply has five storage locations in non-volatile memory to store
power supply states. The locations are numbered 1 through 5. You can assign
a name to each of the locations for use from the front panel.
• You can store the power supply state in any of the five locations. However,
you can only recall a state from a location that contains a previously stored
state.
• The power supply stores the following: the state of output range selection,
flashing digit position on the display, the limit value settings of voltage and
current, output on/off state, OVP on/off state and trip levels.
• When shipped from the factory, storage locations ‘‘1’’ through ‘‘5’’ are empty.
• You can assign a name to the storage locations. You can name a location
from the front panel or over the remote interface but you can only recall a
named state from the front panel. From the remote interface, you can only
recall a stored state using a number (1 through 5).
• The name can contain up to 9 characters. A letter (A-Z) or numbers (0-9)
can be used for the first character to name a state. The underscore character
(‘‘_ ’’) can be used for the remaining 8 characters. Blank spaces are not
allowed. An error is generated if you specify a name with more than 10
characters.
•A power-on reset (
*RST
command) does not affect the configurations
stored in memory. Once a state is stored, it remains until it is overwritten.
• Front-Panel Operation:
STORE STATE, NAME STATE, EXIT
To reset the power supply to the power-on reset state without using the
*RST
command or turning power off/on, select the ‘‘
RESET
’’ from the
following.
5 states, RESET, exit
Store
Recall
