keys should be held down for 3 seconds. Set: SonG will
be displayed in the Speed display bar, and the number below will flash.
Rotate the knob key to set the type of prompt tone, with numbers 1-4
indicating the type of prompt tone and 5 indicating the shutdown prompt
tone (single system error and door opening/closing sound still present).

The instrument provides 10 sets of custom memory
programs for different experimental parameters. P1-P5 is a commonly used
shortcut key on the control panel, and P6-P10, please press the
key to enter. To cancel storage and switch to normal operation mode, press
the

After the machine speed stabilizes, if necessary, the parameters such as
speed/centrifugal force, time, and lifting speed can be modified again. After resetting
the parameters, there is no need to manually confirm, and the system will
automatically flash three times to confirm the settings.
●
Before setting parameters, the rotor must be correctly installed on
the shaft.
●
If an error is found during the parameter setting process, the
parameters can be reset.

On the Calculation of Centrifugal Force
The relative centrifugal force is generally thousands of times of Gravity of Earth
(g). It is a unit used to measure the efficiency of various instruments in separating or
depositing objects. The calculation of centrifugal force is related to centrifugal speed
and centrifugal radius, and is calculated according to the following equation:
RCF=1.18
×
(n/1000) 2
×
R
r: Is the centrifugal radius, in cm;
n: Centrifugal speed in rpm (revolutions per minute)
Note: "The maximum centrifugal force value is related to the maximum
centrifugal radius";
The "centrifugal force value" set should take into account the radius of the rotor
and the shape of the centrifugal container.
