Run-Parameter Keys
Run-parameter keys are used to enter specific run information as follows. The centrifuge emits an
audible tone when each key is pressed. (Instructions for disabling the tone are in
CHAPTER 2
).
ROTOR
Displays the name of the selected rotor.
ACCEL
When the
ACCEL
key is pressed, one of ten available acceleration rates can be
entered. Displays the selected acceleration rate throughout the run.
DECEL
When the
DECEL
key is pressed, one of eleven available deceleration rates can be
entered. Displays the selected deceleration rate throughout the run.
PROGRAM
•
During setup—when the
PROGRAM
key is pressed, a program number (one of ten
possible) can be selected and program parameters entered.
•
During centrifugation—the number of the program being run is displayed.
Pressed to display scrollable list of compatible rotors. Can be pressed repeatedly to
scroll through the rotor list (or the arrow keys can be used for scrolling).
If the display shows speed in RPM, the key is pressed once to enter run speed (using
the keypad) in RPM (revolutions per minute); pressed twice to enter run speed in RCF
(relative centrifugal field). If the display shows speed in RCF, the key is pressed once
to enter speed in RCF or twice to enter speed in RPM.
Pressed to enter run time using the keypad. When
TIME
is pressed twice,
HOLD
mode
is selected. (Pressing it again reverts to time-entry mode.)
•
Timed run—Run time up to 99 hours and 59 minutes can be set. If more than
59 minutes are entered in the minutes field, the system automatically converts
the entry to hours and minutes. Deceleration begins when the set time counts
down to 0.
•
Continuous run (hold)—For runs of unspecified lengths, hold mode is used. When
99 hours, 59 minutes is reached, the system resets to 0 and continues counting.
A hold run continues until the
STOP
key is pressed.
Pressed to enter temperature (using the keypad), from 2 to +40°C. If a new
temperature is not entered, the centrifuge uses the temperature set for the
previous run.
Enables selection of one of ten preset acceleration rates (see
Table 2.1
in
CHAPTER 2
)
available to protect specific gradient and sample-to-gradient interfaces. If
no acceleration rate is selected, the centrifuge defaults to maximum acceleration.
Enables selection of one of eleven preset deceleration rates (see
Table 2.1
in
CHAPTER 2
) available to maintain optimum separation. If no deceleration rate is
selected, the centrifuge defaults to maximum deceleration. (Deceleration rate 0 is
always coast to complete stop.)
