可以把预冷速度从 500 RPM 调到转子的最大转速,调整步进为 10。预设值是 2800 RPM
When the rotor is stationary and the lid open the pre-cooling speed can be set in the following manner:
当转子是静止且盖子打开的时侯,可以用下面的方式来设定预冷速度。
Hold down the key
for 8 seconds. 按住 8 秒钟。
After 8 seconds,
appears in the display. 8 秒钟后, 会出现在显示屏中。
Press the key
once again. The set pre-cooling RPM - will be displayed.
再次按
键。 将会显示设定的预冷 RPM:
Set the desired pre-cooling speed using the knob
用旋钮 来设定想要的预冷速度。
Press the key
in order to store the setting. As confirmation, is displayed for
a short period.
键来保存设定。 会出现在显示屏上一会儿,以表示确认。
20 Relative centrifugal force (RCF) 相对离心力
The relative centrifugal force (RCF) is given as a multiple of the acceleration of gravity (g). It is a
unit-free value and serves to compare the separation and sedimentation performance.
相对离心力(RCF)是重力加速度的倍数,没有单位,用来比较分离及沉淀性能。
These values are calculated using the formula below: 用下面的公式可以计算这些值。
RCF = relative centrifugal force 相对离心力
RPM = rotational speed (revolutions per minute) RPM= 旋转速度(每分钟的转数)
r = centrifugal radius in mm = distance from the centre of the turning axis to the bottom of the
centrifuge. For more on the centrifugal radius see the chapter ” Anhang/Appendix, Rotoren und
Zubehör/Rotors and accessories”. r= mm 为单位的离心半径=转轴的中心到离心管底部的距
离。有关离心半径的更多信息,见附录,转子与配件这一章。
相对离心力(RCF)与每分钟的转数及离心半径成比例。
