How do I save the present state of the instrument?
You can save the settings in the instrument using the front-panel menus or from a remote interface.
After they are saved, you can recall them or copy them to a USB flash drive.
From the front panel:

Where
<n>
is an integer from 0 to 4.
In the front panel script menus, the setups saved with the
*SAV
command have the name
Setup0
x
,
where
x
is the value you set for
<n>
.
Using TSP commands:
Configure the instrument to the settings that you want to save. To save the setup, send the

Why did my settings change?
Many of the commands in the Model 2450 are saved with the source or measurement function that
was active when you set them. For example, assume you have the measurement function set to
current and set a value for NPLCs. When you change the measurement function to voltage, the
NPLC value changes to the value that was last set for the voltage measurement function. When you
return to the current measurement function, the NPLC value returns to the value you set previously.
