4.5 Selection of operating time and momentary operation
Operation of the centrifuge begins when the timer knob is turned
clockwise to set a run time. For run times less than 5 minutes,
turn the knob clockwise past the halfway point and then counter-
clockwise to the desired time. For run times longer than 5
minutes, turn the knob clockwise to the desired time.
When the preselected time expires, the centrifuge will stop
automatically. To stop the centrifuge prior to the expiration of
set time, turn the timer knob to the zero position.
The centrifuge may be operated manually by pressing and
holding the quick button. The centrifuge will continue to run as
long as the button is depressed.
Some models are equipped with a timer that includes a hold
position. Continuous operation of these models may be achieved
by turning the timer knob firmly to the left. The centrifuge will
continue to operate until the knob is turned to the zero position.
Note: The timer knob may be turned in either direction during
operation of the centrifuge without damage to the timer mecha-
nism.
