TIME
• In time mode, 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.
• In hold mode, indicates the time elapsed since [
START
]
was
pressed. After 99 hours and 59 minutes the timer will reset to 0 and
continue counting elapsed time.
• In
ω
2
t
mode, indicates user-entered
ω
2
t
(accumulated centrifugal
force on the sample) and the calculated time remaining until the
ω
2
t
setting is reached.
TEMP °C
Indicates rotor temperature in degrees C. The temperature is
displayed to 1 degree and is within ±2 degrees of the set temperature
(after temperature equilibrium is reached).
Setup Screen
The setup screen (Figure 2-4) contains editable fields for parameter
entry. The six function keys to the left of the screen are for selecting
parameter fields. The six soft keys to the right of the screen are used
to select options based on which function key is pressed. Guidelines
direct the eye from each function and soft key to the display line
controlled by that key. A message line at the bottom of the screen
shows help, informational, and diagnostic messages during setup and
operation.
