Imbalance Diagnostics
The Allegra X-12/R, X-15R centrifuge has a rotor imbalance detector as used in the Allegra 25/64R.
In a situation where an imbalanced rotor is being used an Imbalance diagnostic will be generated and
the instrument will brake the run to a stop. The system reports imbalance diagnostic if the sensor
reading is positive and the door is closed.
