Upgrading the firmware
To upgrade the Model 2450 firmware, you load an upgrade file into the instrument. You can load the
file from the USB port using the remote interface or the front panel of the instrument. If you are using
Test Script Builder (TSB), you can upgrade the firmware from TSB using a file saved to the computer
on which TSB is running.
During the upgrade process, the instrument verifies that the version you are loading is newer than
what is on the instrument. If the version is older or at the same revision level, no changes are made.
If you want to revert to a previous version of the firmware, press the
MENU
key on the front panel,
select
Manage
, and then select
Downgrade to Older
instead of Upgrade to New. When you return to
a previous version, the instrument verifies that the version you are loading is earlier than what is on
the instrument.
The upgrade process should take about five minutes.
To locate the upgrade files on the Keithley website:
1. Select the
Support

progress. Wait until the instrument completes the upgrade procedure and the opening display is
shown.
