Select 100 mV.
Highlight the time constant.
Select 1 second.
Display the Disk menu.

Now we need a file name.

key. The numbers function as normal.
Type a file name such as TEST1 (or any legal
DOS file name) and turn off the ALT mode.
This saves the setup to disk using the file name
specified above. If the entered file name has no
extension, then the extension .85S is appended to
the file name.
Change the lock-in setup back to the default
setup. Now let's recall the lock-in setup that we
just saved.
Check that the sensitivity and time constant are 1V
and 100 ms (default values).
Display the Disk menu.
