If the test tool is not powered through its power adapter,
removing the battery for 10 minutes will clear all data
stored in SRAM. For this proceed as follows: disconnect
the test tool from all voltage sources, open the battery
door on the rear panel and remove the battery. This
deletes the last-used screen and instrument setup state
and any user-saved screens and instrument setups.
