Description
[
TIME
]
Pressed to select the run duration, using the cursor keys.
•
Timed run—
can be set up to 9 hours, 59 minutes (a minutes
parameter exceeding 59 is automatically converted into hours).
•
Continuous run—
timer is set for less than 0 or more than 9 hours,
59 minutes (by pressing the down cursor key after the display
reaches 0, or the up cursor key after the display reaches 9:59).
[
TEMP
]
When this key is pressed, the
TEMP°C
display flashes, indicating
that the temperature can be entered with the cursor keys. Temperature
can be set between –20 and +40°C.
[
S
] [
T
]
(Cursor Keys)
Up and down arrow keys, which can be pressed to increment
parameter values up or down.
[
ENTER
]
Pressed after each parameter is entered to register the entry. Also
pressed to verify parameter changes (speed, time, temperature, and
deceleration rate) made during a run in progress.
[
ACCEL
]
Enables selection of one of 10 preset acceleration rates (see Table 3-1
in Section 3), available to protect specific gradient and sample-to-
gradient interfaces. If no acceleration rate is selected, the centrifuge
defaults to maximum acceleration.
[
DECEL
]
Enables selection of one of 10 preset deceleration rates (see Table 3-1
in Section 3) available to maintain optimum separation. If no deceler-
ation rate is selected, the centrifuge defaults to maximum
deceleration. (Deceleration rate 0 is always coast to complete stop.)
Digital Displays
The displays indicate rotor speed, run time, rotor chamber tempera-
ture, and numbers representing selected acceleration and deceleration
profiles. The displays serve a dual purpose.
• When the run parameters are being entered (input mode), they
show the set values selected. When a parameter key is pressed, the
appropriate display flashes to indicate that data can be entered.
