8.2.1 Restoring to Factory Defaults
The instrument can be returned to its factory defaults condition, as described above, from
Setup/Functions > Setups > Load Defaults (see section 4.9.1).
8.3 Power-On State
The set-up of the instrument each time that it is turned on (from off) is normally set t
o “Last
Used”. This results in no change occurring when the instrument is powered off and then back
on.
Alternatively, the user can choose to load the User Preset which overwrites the major settings
with ones chosen by the user (see section 4.11.1). This choice is made from:
STATUS >System Utils > Power/Clock > Pwr-On State - see section 4.10.3.2.
