The Model SHKE8000-7 Series Shaker has the ability to hold the product
at a specific temperature after operating for a predetermined time.
Control
A typical example is shown at
right. In this example, the shaker
is operating at 250 RPM with
cabinet temperature at 37°C. The
06:30 time value in the lower left
corner of the display indicates that the shaker is counting down and will
stop motion in six and one-half hours.
The illustration at right shows
that time has counted down to
zero and the shaker platform has
stopped (zero RPM's). The
temperature value of 5.0° in the
lower right corner of the display is the temperature at which the product is
being held. Hold will continue at this temperature until the Start button is
pressed or a new Hold or operating temperature is entered.
