Turn the key to the right (clockwise) to the normal posi-
tion for routine closed-door centrifugation. The key should
be removed while in this position.
Keep the key inserted vertically to run the instrument in
locked operation. The key should be removed while in this
position.
Turn the key to the left (counterclockwise) to the zonal
position for runs in which a zonal rotor is being used. The
key cannot be removed while the instrument is running in
a zonal operation.
NOTE
As a safety feature, after you press
you must reset the key by turning it clockwise out of the
zonal position and then back again into the zonal posi-
tion. Then press
zonal run (see Section 8).
When the instrument is running in zonal or locked operation, "ZONAL" or
