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 nine characters. A letter
(A- Z) or number (0- 9) can be used for the first character
to name a state. The underscore character (“_”) can be
used for the remaining eight characters. Blank spaces are
not allowed. An error is generated if you specify a name
with more than nine 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.
