Settings
Time - With the time set at Hold, the time display in the upper left por-
tion of the screen begins to count upward, showing the total operating
hours and minutes. The system resets to 00:00 whenever the unit is
stopped and restarted, using the Stop and Start buttons. The unit will
not reset if the unit is turned off and on using the power switch, or if the
cover is repeatedly opened and closed.
Speed - The Actual speed will display zero RPM’s and will gradually rise
as the platform begins its motion.
Temperature - The temperature, shown in the upper right portion of the
liquid crystal display, will indicate the actual ambient temperature inside
the cabinet and will slowly move toward the 37° setpoint.
The values shown in Figure 2-2 are set at the factory and are considered
default values. Other factory settings are shown in the table following.
To get the most from the shaker’s microprocessor-based technology, the
SHKE420HP can be easily programmed to meet the most demanding
laboratory requirements. The following sections outline the procedures for
changing the settings and for programming the shaker control system.
When first turned on or when the shaker is operating, Temperature, Time
and RPM values are displayed on the LCD. A typical screen is illustrated
in Figure 2-2. For convenience, this is called the Operating Screen
throughout these instructions. All programming or setting changes start
from this screen.
The instructions to program the SHKE420HP are written in a step-by-
step format. For convenience, the instructions begin and end at the
Operating Screen.
