Backing Up the Setup Information
The setup information listed below is stored using the lithium battery. When the power
switch is turned ON, the TA120E starts the measurement using the settings that existed
immediately before the power switch was turned OFF. If the setup information can no
longer be stored due to a dead lithium battery, the TA120E is reset to the factory default
settings. For factory default settings, see section 7.4.

the ON/OFF condition of the numeric display (see section 5.2), the ON/OFF condition of key
lock (see section 7.6), and GP-IB address (see section 8.4) are the same.
