Description
Digital Display
The display shows current status of the instrument whenever the
power is turned on.
• The display shows both actual centrifuge values and user-set
parameters. The
key is used to toggle between the
two views.
• During a run, actual values are displayed. If you turn a knob (other
than the TIME knob) during operation, the display will change to
show the set values. If no parameters are entered or changed for
5 seconds, the display will revert to showing actual values.
• During a timed run, the
TIME
display shows the
remaining run
time in hours and minutes
. The
TIME
display begins counting
down when
_78%68a
is pressed and continues counting down to 0,
when deceleration begins. When the rotor decelerates to 0 rpm,
“End” flashes in the
TIME
display.
• When HOLD is selected (no run time is specified), the
TIME
display shows the
time elapsed since
_78%68a
was pressed
. After
3 hours (180 minutes) have elapsed, the timer will reset to 0 and
continue counting elapsed time until
_7834a
is pressed.
Knobs and Touch Keys
The rotor name, speed, time, and temperature settings are entered by
turning the appropriate knob until the required value is displayed.
Touch keys allow the user to start and stop the centrifuge, and to
select speed mode (RPM or RCF), time mode (specific run length or
hold for continuous operation), and acceleration and deceleration
rates, and to toggle the display between set and actual values.
ROTOR Knob
Used to select the rotor in use. As the knob is turned, the name of
each Beckman Coulter rotor that can be run in the centrifuge appears
in succession in the
ROTOR ID
display, and the LED by each rotor
type abbreviation (JCF: continuous flow rotors; JSP: special type
rotors; JS: swinging bucket rotors; JA: fixed angle rotors; JLA: light-
weight fixed angle rotors; JV: vertical tube rotors; JE: elutriator
rotors) lights when appropriate.
