Press the
[START]
button.
The
[START]
button lamp blinks and the rotor starts turning.
The timer begins operating. (If the actual run timer is set, the
timer will start operating when set speed is reached.)
When the set speed is reached, the
[START]
button lamp
changes to steady lighting and a white dot of light starts to
spin around the button
The rotor stays in standby at 4,000 rpm until a medium
vacuum level is reached.
8
Operation stops when the set
centrifugation time has
elapsed (end of run). Or press
the
[STOP]
button.
The
[STOP]
button lamp blinks and the rotor starts
decelerating.
9 The rotor stops.
The
[STOP]
button changes to steady lighting.
The buzzer sounds to indicate the rotor has stopped.
10 Press the
[VACUUM]
button.
The vacuum pump stops, the air leak valve starts operating
to return the rotor chamber to normal atmospheric pressure.
The door lock is released and the door can be opened.
When the rotor chamber returns to normal atmospheric
pressure, the "Now open the door" message appears above
the
[VACUUM]
button.
11 Remove the rotor.
Gently remove the rotor when it has stopped.
If the rotor chamber is not properly evacuated before operation, or room temperature is low
(10C or less), the evacuation may take time and the centrifuge will operate at 4,000 rpm. If the
chamber is not properly evacuated, the rotor may slow down before the set speed is obtained to
continue evacuation. Therefore, it is recommended that you use the
[VACUUM]
button before
operation to evacuate the chamber for about 15 minutes or until the indicator above the
[VACUUM]
button indicates that a high vacuum level has been reached.
