Description
Digital Displays
The displays provide run information, user messages, and
diagnostics.
• During a run, they show the actual (real-time) operating
conditions.
• When the run parameters are being entered, they show the set
values selected. Set values can be recalled during operation by
pressing [
SHOW SET
]. After 5 seconds, the displays return to actual
conditions.
(SPEED)
Indicates rotor speed in revolutions per minute (rpm) or in relative
centrifugal field, a term describing the ratio of the centrifugal acceler-
ation at a specified radius and speed to the standard acceleration of
gravity (RCF
×
g
).
(TIME)
• In a timed run, indicates the remaining run time in hours and
minutes. The time display begins counting down when [
START
]
is pressed and continues counting down to 0, when deceleration
begins. The run automatically ends when the set time reaches zero
(a tone sounds when the rotor stops spinning). If a malfunction
shuts down the centrifuge during a run, the time counting stops and
the time remaining when the run stopped remains in the display.
By comparing this time with the original set time, you
can determine when the run ended.
• In a hold run, indicates the time elapsed since [
START
] was pressed.
After 99 hours and 59 minutes the timer resets to 0 and continues
counting elapsed time.
(TEMPERATURE)
Indicates rotor temperature in degrees C at thermoequilibrium. The
displayed temperature is within ±2 degrees of the set temperature
(after equilibration).
(ROTOR)
Displays the name of the installed rotor.
(ACCEL)
When the [
ACCEL
] key is pressed, an acceleration rate (1 = MAX,
2 = SLOW) can be entered. If no number is entered, the instrument
accelerates at the rate set for the previous run.
(DECEL)
When the [
DECEL
] key is pressed, a number representing the selected
deceleration rate (1 = MAX, 2 = SLOW, 3 = OFF) can be entered. If
no number is entered, the instrument decelerates at the rate set for the
previous run.
