5.2 Speed Check
Required equipment: Calibrated and reflective adhesive optical tachometer.
Place a reflective strip on the central part of the rotor.
Remove the plug sealing the central porthole under the lid.
Close lid.
Start a cycle at the desired speed
When the setpoint speed is reached, place the speedometer on the central porthole.
The speed displayed in the measurement device must be equal to that displayed on the screen, within a tolerance
of ± 10 rpm
If this is not the case, check that the reflective tape is well placed in the central part of the rotor, and firmly hold the optical
tachometer, without movement during the measurement.
5.3 Checking the Timer
Required equipment: Calibrated stopwatch.
Define a centrifugation cycle of the desired duration (e.g.: 10 min, 4500 rpm, acceleration 9, braking 9).
Start the cycle by pressing start.
To start the centrifuge stopwatch, operate the stopwatch.
Stop the stopwatch at the end of the programmed time. Check that the centrifuge starts to brake well.
