Acceleration and deceleration rates
Thermo Scientific WX Ultra Series 2-17
Acceleration and deceleration rates
In order to meet various experimental protocols, the acceleration and deceleration rates can be adjusted
between 0 to 500 rpm.
The figure and table below show the relationship between ACCEL/DECEL code numbers selected and
resulting approximate acceleration/deceleration times.
13 Open the chamber door. >> For details, see zonal rotor manual.
14 Remove the cap assembly
15 Install the seal assembly and unload the sam-
ple.
16 On the Run Screen, move the cursor to ZONAL
in the FUNCTION field and enter the following
by operating numeric keys to set the normal
operation mode.
>> Rotor decelerates to a stop.
Note During the zonal mode, the rotor will not decelerate even if the
STOP key is pressed during the rotor's spinning at the zonal sped.
17 Be sure that the rotor is at rest, then remove the
rotor.
>> If the rotor is still spinning, do not remove it. Wait until it comes to a complete
stop.
Note By changing to the NORMAL mode when loading and unloading the sample, you can
decelerate the rotor to a stop.
