INSTRUCTIONS FOR USE
Thermo Fisher Scientific MR23i 5-3
Note If the instrument remains switched on, but not used, then 5 minutes
after the end of the last run the screensaver operates. The backlight
is extinguished although the display can still be read. Press any key
to light up the screen then continue with normal operation.
USE
INTRODUCTION
The VIDEOset graphics based control software is designed to com-
bine power with simplicity. Unlike usual programming systems,
where the user is obliged to follow a linear parameter input from
beginning to end,VIDEOset enables the operator to go directly to
those parameters of interest, neglecting unrelated parameters.
No previous operational knowledge is necessary; the programming
is really intuitive. On-screen guidance is given to enable the user to
optimise the capabilities of the instrument.
The screens presented in this manual could differ slightly according
to the version of the software.
SWITCHING ON
Immediately after switching on, the screen displays Thermo Elec-
tron Corporation, then the stand-by screen is displayed showing
the number of the last application program used and its basic para-
meters.
NONE Selects “NO PASSWORD PROTECTION” when
memorizing an application.
PRE COOL Starts a predetermined precooling cycle (2000
rpm, 4°C, 15 min). During this cycle all other pro-
gramming facilities are operational.
RADIUS Enables the effective radius of a selected rotor to
be modified in order to allow for the use of an
adaptor or to select a boundary at which a set “g”
force can be applied.
ROTOR Lists the available rotors from which a selection
can be made with their capacity and perfor-
mance.
SAVE APPLI Allows the current set of parameter values (com-
plete or incomplete) to be stored in one of 32
memories, with or without an individual pass-
word.
SCROLL APPLI # One press displays all parameter values of next
used memory. Continued presses will display the
values for all memorised applications. Also acts
as application (program) selection key.
START Starts the run.
STOP Stops the run, overiding any programmed time or
integral.
