Hi Rob,
that's easy.
Configure your 34465A to TEMP, and the sensor settings you need.
Then go to Utility - Store/Recall, select a name for your setting, and STORE STATE
Whenever you recall this state, it will exactly come up in this configuration.
You can also make this setting your default boot setup by storing the configuration and setting the DMM to "Power on - User defined". See manual for details, where /how to store this correctly.
