Starting A Run; Stopping A Run - Thermo Scientific IM448 Instruction Manual

3. Load the rotor symmetrically with 2, 3, 4, or 6 tubes in the 6-place rotor (but not 1 or 5) or 2, 3,
4, 6, 8, 9, or 12 in the 12-place rotor (but not 1, 5, 7 or 11).
The tubes must be of equal size and with contents of equal (within 1 gram) weight.
4. Close the cover securely, ensuring that the latch is engaged.

Starting a Run

1. Turn the timer knob to the desired run duration.
For runs of under 5 minutes, turn the timer past the five minute setting and then back to the
desired time).
For runs in the HOLD mode (infinite duration), turn the knob speed counter-clockwise to the
∞setting.
The motor will take several minutes to reach top speed..
Note Periods of slight vibration during acceleration are normal. If excessive vibration occurs, turn
the timer knob to zero (0). When the rotor has come to a stop, open the cover and check that the
load is balanced. If the rotor is properly balanced and vibration persists, ensure that the suction cup
feet are clean and adhering to the surface on which the unit was placed.

Stopping a Run

1. To stop a run, turn the timer knob to zero or allow the time to expire.
2. Wait until the rotor has come to a complete stop, then unlatch and open the cover.
