Operation
Section 2
Models 416 and 430 are microprocessor-controlled tabletop orbital shakers
designed to accommodate a wide variety of flasks, test tubes and other
glassware. The control system, common for each, is easily programmed and
stores the user-defined time and speed settings which remain in memory
even when the shaker is turned off and unplugged.
The computer-based speed controller continuously adjusts for line voltage
fluctuations and provides smooth start-ups and consistent RPM control.
The circuitry is designed to slowly bring the platform up to speed and
down to a stop to prevent liquid splashing from flasks or test tubes.
Warning The microprocessor speed control system may take up to one
minute to bring the platform up to speed. Never leave the shaker
unattended when starting it. Make sure all flasks and test tube racks are
firmly seated in the clips and check the security of the flask clip and
platform attachment screws weekly.

Optional Temperature
A factory-installed Temperature Monitoring kit enables in-flask
temperatures to be monitored and displayed on the control panel display

screen. A temperature probe is immersed in the medium and plugged into
a connector on the back panel of the shaker. The probe may also be used
to monitor ambient temperatures.
Figure 1-16 shows the location of the Temperature Probe Connector.
