No. Name and Symbol Functions and actions
(1) Field display
SPEED
TIME
TEMP
Displays various fields.
The SPEED, TIME, and TEMP fields give the current status indicator in the top row and the
setting indicator in the bottom row. (For setting, see Section “Setting run conditions”.)
• SPEED (Speed indicator)
(Top row) Displays speeds in increments of 10 rpm at lower than 5,000 rpm, and in steps of 100
rpm at 5,000 rpm or more.
(Bottom row) Sets speeds from 1,000 to maximum speed in increments of 100 rpm. The lower two
digits (one, ten positions) display zeros.
• TIME (running time indicator)
(Top row) Displays the remaining operation time or the time elapsed during operation if settings
are performed on the User Customization screen. If the running time is set to HOLD, this field
displays time elapsed.
(Bottom row) Specifies a setting in the range from 1 minute to 99 hours 59 minutes in steps of
minutes and hours.
• TEMP (temperature indicator)
(Top row) Displays in steps of 0.1 °C.
(Bottom row) Sets a setting in the range from 0 °C to 40 °C in increments of 0.1 °C
• ACCEL (acceleration mode indicator). Displays acceleration modes 1 through 9.
• DECEL (deceleration mode indicator). Displays deceleration modes 1 through 9, along
with free coast (F).
(2) Function field • ID CODE Sets an ID code.
• RLM Switches to the Rotor Management screen.
• PROG • RTC Sets, recalls programmed runs or sets the time and the end time for a
programmed run.
• RCF • ω
2
T Sets and displays the centrifugal force or sets an ω
2
T
• DEF Sets and resets the defrost function.
• ZONAL Sets the zonal operation mode.
(3) Message indicator Displays an alarm message and various suggestions for operation.
(4)
Run mode indicator
The following terms are displayed:
STOP, ACCEL, RUN (running at the set speed)
DECEL, WAIT (waiting for vacuum during acceleration)
ZONAL (for zonal operation)
DELAY (until the start time in an RTC run)
(5) VACUUM indicator Displays the following four stages according to the vacuum of the rotor chamber.
(1) Atmospheric state. The vacuum pump is not activated.
(2) Low vacuum. The rotor waits at 4,000 rpm until the vacuum reaches an inter-
mediate level
(3) Intermediate vacuum.
(4) High vacuum.
Note If the sample is sensitive to a temperature rise, do not press the START key until the
chamber is at high vacuum level.
