7.0 Operation

CAUTION: Never attempt to operate the centrifuge with rotors or adapters that show signs of corrosion or mechanical damage. Never
centrifuge strongly corrosive materials that may damage the rotors, accessories, or bowl of the unit.

7.1 Attaching Rotor Lid

After the rotor has been properly secured and loaded, attach the rotor lid to the rotor. Always use the rotor lid for safety and to
allow the rotor to reach proper speed. Make sure the rotor lid snaps securely into place, by pressing down on center catch.

7.2 Closing the Lid

Close the centrifuge lid. This microcentrifuge has a lid lock that activates only when a run is started.

7.3 Lid Release

The lid will remain locked during a centrifuge run. Once the run has been completed and the rotor has come to a stop, a beep will
indicate the end of a run, and the lid will unlock automatically.
CAUTION: Do not attempt to open the lid of any centrifuge until the rotor has come to a complete stop.
In the event of a power failure or malfunction, it may be necessary to open the lid manually.
1. Disconnect the power cord from the wall socket.
2. Remove the plastic plug, located on the left side of the unit.
3. Pull the wire (attached to the plug) to open the lid lock manually.

7.4 Lid Lock

The centrifuge can be started only when the lid is securely closed. When a run is started, the lid lock automatically activates.
CAUTION: Do not attempt to open the lid during a centrifuge run. At the end of the run, the lid will automatically unlock. Never
attempt to override the lid lock mechanism. Doing so is dangerous and could damage the centrifuge.

7.5 Speed Selection

The speed (rpm or g-force) can be selected from 500 to 15,000 rpm in 100 rpm increments or from 100 to 21,200 x g with the
control knob. The speed is selected by pressing the RPM or RCF button. The speed signal will begin to blink. Then, turn the control
knob to increase or decrease the value.

7.6 Selection of Operating Time, Momentary Operation, Start/Stop

Operating time can be selected from 0.5 min. to 99 min. by pressing the TIME button and adjusting with the control knob. The time can
be set in 0.5-minute increments from 0 to 10 minutes and in 1-minute increments from 10 to 99 minutes. After 99 minutes, the display
shows "--" which indicates continuous run. In this mode, the centrifuge will run until manually stopped. To start a run, press the control
knob. When the preselected time expires, the centrifuge will stop automatically. To stop the centrifuge prior to the expiration of set
time, press the control knob. The centrifuge may be operated for a short run by pressing and holding the control knob. The centrifuge will
continue to run as long as the control knob is depressed, the time (in seconds) will count up on the time display.
