Standby cooling will be subject to a timed delay after a centrifuge run and the display will
show
. The delay time can be pre-set in 1minute steps from 1 to 5 minutes.
It is pre-set to 1 minute.
在每次离心完成后，待机冷却将在一个预设的时间后启动，可以设定延迟时间为 1－5 分钟，步
进 1 分钟，出厂值是 1 分钟。在待机冷却时，显示屏会显示
。
With the rotor standing still and the cover open the delay time can be set as follows:
当转子是静止且盖子打开的时候，可以按照如下设置延迟时间：
_ Hold down the key
for 8 seconds. 按住 键 8 秒钟。
After 8 seconds, t/min = X appears in the display. 8 秒钟后，t/min=X 会出现在显示屏中。
_ Use the rotary button
to set the delay time. 用旋钮 来设定延迟时间。
Press the key
in order to store the setting. As confirmation, is displayed for
a short period. To leave the delay time display press the key
or do not press any key for a
period of 8 seconds.
按
键来保存设定。 会出现在显示屏上一会儿，以表示确认。 按
键来退出延迟时间显示，或者 8 秒钟内不按任何键。
19.2 Pre-cooling the rotor 预冷转子
Press the key
.The LED in the button lights up for as long as the rotor turns.
按下
键，转子开始转动，且 按钮中的 LED 会亮起来直至转子停止转动。
Press the button
to end the pre-cooling. The run-down is effected with the selected
brake step. The brake step is displayed. During the centrifugation run the rotational speed of the rotor
or the subsequently resulting RCF value, the sample temperature and the expired time will be
displayed.
按
键来终止预冷过程。根据选择的减速步骤转子逐渐停转。减速步骤会显示出来。
在离心过程中，将会显示转子的转速或者相应的 RCF 值、样品温度（只针对带冷却的离心机）
及已用时间。
The pre-cooling speed can be adjusted in decadic steps from 500 RPM to the max RPM of the rotor. It
is pre-adjusted to 2800 RPM.
