MEMORY
You can save your regular INGVAR settings in this
menu option. Moreover you can, for example, prepare
settings in advance and save them so that they can be
recalled whenever desired. INGVAR has ten memo-
ries numbered 0-9 where you can save settings. The
memories retain their contents even when power to
the INGVAR is turned off.
When you start INGVAR, the settings saved in memory
number 0 are loaded automatically. This means that
if you want a specific set of settings to be used the
next time you turn INGVAR on, you can save them in
memory 0 before turning INGVAR off. There is one
additional memory called the standard memory in
which the factory settings are kept, these factory set-
tings cannot be changed.
The available settings are listed in the table below.
