Description
Controls and Indicators
1
Digital Displays
Digital displays indicate rotor speed, run time, rotor chamber temperature, and numbers that
represent selected acceleration and deceleration profiles (see
Figure 1.6
). When the power is turned
on, they show the operating parameters of the most recent run performed before the power was
turned off. The displays serve a dual purpose.
•
When the run parameters are being set (the input mode), the displays show the set values
(those selected by the operator). When a run- parameter key (for example,
TIME
or
RPM
) is
pressed, the appropriate display flashes to indicate that data can be entered.
•
The
actual
(real-time) operating conditions of the centrifuge are displayed during the run, after
START
is pressed.
NOTE
Error messages (see Section 4) also appear on the displays, when applicable. The centrifuge emits a
series of audible tones to alert the user to an error condition.

Digital Displays
RPM/RCF/ROTOR
•
In input mode
the RPM/RCF/ROTOR display shows the value of the parameter
being set, depending on the programming key pressed (
RPM
,
RCF
, or
ROTOR
).
For example, if the
ROTOR
programming key is pressed, a rotor number
appears on the
SPEED
display.
•
During centrifugation
, the
SPEED
display shows the speed of the rotor in rpm.
If the
RCF
key is pressed while the centrifuge is running, the RCF value is
displayed.
TIME
•
During a
timed run
(between 1 minute and 9 hours, 59 minutes), the
TIME
display begins counting down when the rotor starts to spin and continues the
countdown until deceleration begins. The
TIME
display indicates the remaining
run time in hours and minutes.
•
During a
continuous run
(less than 1 minute or more than 9 hours, 59 minutes
selected), countdown time is not displayed. Instead, the infinity (
) symbol,
indicating continuous operation, lights up and the
TIME
display shows time
elapsed since the run start. After 9 hours and 59 minutes the timer resets to 0
and continues counting elapsed time.
TEMP °C
(refrigerated
models only)
During standby (that is, the centrifuge is turned on but not spinning) and operation,
the
TEMP °C
display shows the actual temperature inside the rotor chamber (
2°C
at an ambient temperature of 20°C).
ACCEL/DECEL
The
ACCEL/DECEL
display shows the acceleration curve that was selected for the
run. The deceleration curve number can be displayed by pressing the
DECEL
key.
