Description
TEMPERATURE Knob
Used to select the rotor temperature, from –10 to +40°C.
• The minimum and maximum allowable set temperatures depend
on the set speed and the rotor in use. If a temperature is entered
that cannot be achieved by the installed rotor at the set speed, the
TEMP°C
field will flash.
• The maximum achievable rotor temperature depends on the fric-
tional heat generated inside the chamber during operation. At low
run speeds or low ambient temperature, the centrifuge may not be
able to achieve some higher temperatures.
• During operation, if the rotor identification system identifies a
rotor different from the one selected by the user, or if the set speed
is changed, the set temperature may not be achievable and the
TEMP°C
field will flash.
ACCELERATION Key
_%'')0a
Used to select either maximum or slow acceleration. An indicator
light above the
_%'')0a
key displays the selection. Acceleration rates
are described in Table 3-3 (in Section 3).
DECELERATION Key
_()')0a
Used to select maximum or slow deceleration, or off (no brake). An
indicator light above the
_()')0a
key displays the selection. Decelera-
tion rates are described in Table 3-4 (in Section 3).
System Keys
_78%68a
Pressed to begin a run. When
_78%68a
is pressed, the display immedi-
ately shows the actual centrifuge values. The green
_78%68a
light
flashes during acceleration until set speed is reached, and then
remains on continuously until deceleration begins.
_7834a
Pressed to end a run; the centrifuge decelerates to a complete stop
according to the deceleration setting. The red
_7834a
light blinks
during deceleration. Deceleration can be terminated and the centri-
fuge restarted by pressing
_78%68a
.
_'0)%6a
Pressed to stop the flashing of a diagnostic indicator light. See
Section 4,
TROUBLESHOOTING
, for information on diagnostic
messages.
Pressed to toggle the display view between set and actual values.
The indicator for the selected view will be lit.
