Userstrings
Use the functions in this group to store and retrieve user-defined strings in nonvolatile memory. These
strings are stored as key-value pairs. You can use the
userstring
functions to store custom,
instrument-specific information in the instrument, such as department number, asset number, or
manufacturing plant location.

Factory scripts
Introduction
The Keithley Instruments Model 2651A High Power System SourceMeter
®
Instrument is shipped with
one or more factory scripts saved in its flash firmware memory. A factory script is made up of a
number of functions. Some of them can be called from the front-panel LOAD TEST menu. All of them
can be called using remote programming.
As Keithley Instruments develops additional factory scripts, they will be made available on the
(on page A-4) for instructions on upgrading the flash firmware of
your Model 2651A.
A factory script is similar to a user script, except a factory script is created by Keithley Instruments at
the factory and is permanently stored in nonvolatile memory. The differences between a user script
and a factory script include the following:
•
A factory script cannot be deleted from nonvolatile memory.
•
The script listing for a factory script can be retrieved and modified, but it will then be treated as a
user script. A user script cannot be saved as a factory script.
•
Factory scripts are not stored in global variables. The only references to factory scripts are in the
script.factory.scripts
attribute.
•
The
script.factory.catalog()
function returns an iterator that can be used in a
for
loop
to iterate over all the factory scripts.
Example
To retrieve the catalog listing for factory scripts, send:
for name in script.factory.catalog() do print(name) end
