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.
