Description
Controls and Indicators
Program Keys
The program keys are used to set run parameters (a program consists of all of the parameters for a
run). Except for the cursor keys, program keys show the parameters as they are input.
Digital Displays
Digital displays indicate rotor speed, run time, rotor chamber temperature, and the selected
acceleration and deceleration profiles (see
Figure 1.5 ). 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,
MENU
) is pressed,
the appropriate display flashes to indicate that data can be entered.
START/STOP Pressing the START/STOP key causes a centrifuge run to begin. This key can also be
used to abort a deceleration process and restart the centrifuge.
The START/STOP key can be pressed to end a run. The centrifuge decelerates to a
complete stop according to the preselected deceleration curve. Deceleration can be
terminated and the centrifuge restarted by pressing
START again.
OPEN Pressing the OPEN key unlatches the centrifuge door lock and allows the door to be
opened. The centrifuge accepts this command only when the rotor is completely
stopped.
QUICK RUN Manually pressing this key initiates a short run for as long as the key is pressed (applies
only to Microfuge 20).
(cursor keys)
The cursor keys are up and down arrow keys, which can be pressed to increment
values up or down when setting parameters.
PROG Use this key to recall a previously saved program or to enter program mode to save
run parameters as a program.
PRECOOL
(refrigerated
model only)
Use this key to cool the rotor at a slow speed before a run starts. See Precooling the
centrifuge (20R refrigerated models only) for instructions on using this function.
MENU Use this key to scroll through and highlight the different run parameters. The
MENU key is pressed until the appropriate time, speed, or temperature display
function flashes. The parameter is set with the cursor keys.
