Note 1. Select Normal mode when using the sample that is sensitive to a temperature rise. If you
select No Waiting Acceleration, the rotor does not wait until the vacuum reaches an intermediate
level and it might cause the rise in the rotor retention temperature by the friction heat.
2. If the rotor chamber has frost on it by the repeated operation, it takes a long time to reach an
intermediate vacuum. In that case, wipe it off with a cloth, a sponge, etc.
3. Once you select the condition of the waiting for the vacuum (Normal or No Waiting
Acceleration), your micro-ultracentrifuge memorizes this condition of the waiting for the vacuum.
If necessary, change the condition of the waiting for the vacuum.
4. If the low vacuum condition persists for more than one minute in the No Waiting Acceleration
mode while the rotor rotates at the set speed, the alarm message "VACUUM ERROR" is displayed
and the rotor is stopped.
