Two time modes are available. The HR:MIN mode is used for runs of specified
lengths. The HOLD mode is used for continuous runs of unspecified lengths. The
HOLD key is used to toggle between the two modes.
In HR:MIN mode:
• The TIME knob is used to set run time, which can be set up to 3 hours and
0 minutes (180 minutes).
• Each TIME knob increment is 1 minute. A full turn of the knob equals
60 minutes.
• The time setting can be changed during a run.
• During a run, the time remaining in the run is displayed. When 0 is reached, the
run ends and the rotor decelerates to a stop.
In HOLD mode:
• When HOLD mode is selected, the time display shows the word HOLD.
• During a run, the time elapsed is displayed. When the display reaches 3 hours
and 0 minutes, the system automatically resets the display to 0 and begins
counting the elapsed time again. The run will continue until STOP is pressed.
• If you switch from HOLD mode to HR:MIN mode during a run, the system
remembers the previous time setting. Turning the TIME knob increments or
decrements the set time from that point.
Used to select the rotor temperature, from –10 to +40°C.
• The minimum and maximum allowable set temperatures depend on the set
speed and the rotor in use. If a temperature is entered that cannot be achieved
by the installed rotor at the set speed, the TEMP°C field will flash.
• The maximum achievable rotor temperature depends on the frictional heat
generated inside the chamber during operation. At low run speeds or low
ambient temperature, the centrifuge may not be able to achieve some higher
temperatures.
Used to select either maximum or slow acceleration. An indicator light above the
ACCEL key displays the selection. Acceleration rates are described in
CHAPTER 3).
Used to select maximum or slow deceleration, or off (no brake). An indicator light
above the DECEL key displays the selection. Deceleration rates are described in
Table 3.2 (in CHAPTER 3).
