| LABNET 311DS SHAKING INCUBATOR
7.0 Calibration
The Labnet 311DS Shaking Incubator is calibrated at 37°C at the factory. The unit can be recalibrated after the chamber temperature
has stabilized at the setpoint for several hours. Suspend a certified reference thermometer in the chamber. Compare the units display
to the reference thermometer. If there is an unacceptable difference, put the controller into calibration mode by pressing both the
Up and Down arrows at the same time until the two outside decimal points begin to flash. While the decimal points are flashing, the
display can be calibrated to match the reference thermometer by pressing the Up or Down arrows until the display reads the correct
value. Allow the shaker incubator to stabilize again, and recalibrate if necessary.
8.0 Operation
As advised in the installation section, it is very important that the unit be level and placed on a very solid surface. When loading the
platforms, it is also important to load these in a balanced manner or the unit can vibrate and possibly walk. Shaking unbalanced loads
for extensive periods may also damage the shaker.
Before powering on the unit, you should first set the mechanical Safety Thermostat on the back of the unit to a temperature just
above your intended operating temperature or at the maximum (setting of 10).
After you first power on the unit you should notice the shaker display first showing dashes, then the power input line frequency
(F60 or F50 for 60 Hz or 50 Hz), and the temperature controller display showing some random numbers and dots blinking.
The shaker display and temperature display should show the last time that was set (or Hld) for continuous operation, and the
temperature display showing the chamber temperature.
You may now set the desired operating temperature, shaking speed, and shaking time (see Controls section). It is recommended that
you test all loads to be shaken at a slow speed under observation and then gradually raise the speed to ensure the load and unit are
stable. The unit should also be allowed to equilibrate to the set temperature before using.
Once the temperature, shaking speed, and shaking time are set, use the Stop/Start pad to initiate shaking. When shaking in the timed
mode, End will be displayed on the shaker display when the shaking is done. In timed mode Hld (Hold) will be displayed on the shaker
display. The user may switch the shaker display to show the shaking speed by pressing the Push to Shift button.
The user can observe the load being shaken through the glass window and can also turn on the chamber light for additional
visibility. The chamber light should not be left on for an extended period as it adds heat to the chamber and may cause the chamber
temperature to rise above the setpoint .
The user may open the chamber door at any time to gain access to the chamber. If the shaker is running when the door is open, the
shaker power will be immediately cut causing the shaker to slow and stop. The shaker display will show Opn (Open). Shaking will
automatically resume when the door is closed if there is still time remaining on the shaker run.
NOTE:
The clock continues to count
down when the door is open even though the shaker has stopped.
9.0 Cleaning and Maintenance
NOTE:
Be sure to disconnect the power cord before cleaning or decontaminating the oven.
No routine maintenance is required for the electrical or mechanical components of the unit. The incubator exterior, interior, and
shaking platform should be wiped down periodically with a soft damp cloth with mild soap.
NOTE:
Do not use chlorine-based bleach
or abrasives. Any spills in the incubator and/or on the shaking platforms should be cleaned up immediately.
