CONTROL PANEL OVERVIEW
Figure 1 provides an illustration of the control panel.
Figure 1. Control Panel
Power Switch
The main power I/O (on/off) switch controls all power to the unit and must be in the I position before any
systems are operational.
Main Temperature Control
Marked °C, the Main Temperature Control consists of the digital display and Up/Down arrow pads for
inputting set point temperature and calibration.
Heating Lamp
This pilot lamp is ON when the unit is heating up to set point. It is blinking when the controlling
temperature is at set point.
Overtemperature Thermostat
This control is marked SET OVERTEMPERATURE. It is equipped with a graduated dial marked from 0 to
10 and a knob that requires a flat-edged tool for adjusting settings to eliminate accidental changes.
Completely independent of the Main Temperature Controller, the Overtemperature Thermostat guards
against any Main Temperature Controller failure, which would allow the temperature to rise past the set
point. If the temperature rises to the Overtemperature set point, this thermostat takes control of the
heating element and allows continued use of the incubator until the problem can be resolved, or service
can be arranged.

16 Orbital Shaking Incubator
Calibrating the Main Temperature Control
We recommend that you calibrate your unit once it has been installed in its working environment and has
been stable at the set point for 24 hours. To calibrate the unit, perform the following steps:
1. Place a certified reference thermometer in the chamber by placing it either directly inside or through
the access tube at the top left of the unit. Ensure that the thermometer is not touching any shelving. If
you place the thermometer directly inside the chamber, taping the thermometer to a Petri dish will
raise it off the shelf and keep the scale in view.
2. Allow the temperature to stabilize again until the thermometer reads a constant value for one hour.
3. Compare the digital display with the reference thermometer.
4. If there is an unacceptable difference, put the display into calibration mode by pressing both the Up
and Down arrow pads at the same time for approximately five (5) seconds until the display blinks off
and on.
5. While blinking, the display can be calibrated by pressing the Up or Down arrow pads until the display
reads the correct value.
6. Allow the incubator temperature to stabilize again, and recalibrate if necessary.
Setting the Overtemperature Thermostat
To set the Overtemperature Thermostat, perform the following steps.
1. Once the incubator is stable at the desired set point, turn the Overtemperature Thermostat
counterclockwise until the Overtemperature indicator light turns on.
2. Turn the Overtemperature Thermostat clockwise just the safety indicator light turns off.
3. Continue to turn the Overtemperature Thermostat clockwise an additional two small divisions on its
scale past the point where the indicator light went out. This will set the Safety Thermostat at
approximately 1°C above the Main Temperature set point.
Setting the Oscillation Control
To set the oscillation control, perform the following steps:
1. Enter set point mode by pushing and releasing either the UP or DOWN arrow pad one time. The
display will start to blink on and off showing the RPM set point.
2. Push the UP or DOWN arrow pad to increase or decrease the RPM set point in increments of 10
RPM. The range for this set point is 30 – 400 RPM.
3. If the arrow pads are not pressed for five (5) seconds the display will stop blinking and revert to
displaying the actual RPM.
Note: For oscillation controls to work as described, the door must be completely closed.

Setting the Oscillation Stroke
To set the oscillation stroke, perform the following steps.
Note: A 3/16 -inch Allen wrench should be used.
1. Assure that the power cord has been disconnected to prevent accidental operation.
2. Remove sample tray.
3. Open the access panel by rotating the wing nut ¼ turn counterclockwise and rotate the counterweight
platform until the stoke adjuster appears.
4. Remove the locking bolt and adjust the arm to any of the available options.
5. The dimensions shown are the total stroke of the oscillator, i.e., ½ designates a pattern that is + ¼”
from center.
Note: When the stroke has been changed, counterbalance adjustments may be required.
Setting the Counterbalance
To set the counterbalance, perform the following steps:
1. Assure that the power has been disconnected to prevent accidental operation.
2. Remove the sample tray.
3. Open the access panel and rotate the counterweight platform until the counterweight appears.
4. Remove the wing nuts to adjust the counterweights.
Table 3 shows counterbalance starting locations. For example, 5 kg of sample load being shaken with ½
inch stroke will require four counterweights attached to the counterbalance platform as shown in Figure 3.
Loads should be properly counterbalanced before continuous operation. Unbalanced loading may
damage mechanical and electrical operating systems.
