OPERATION
5.1 Check power supply against unit data plate, they must match. Plug service cord into the
grounded electrical outlet, and turn the unit on.
5.2 Turn the Overtemperature Thermostat to its maximum position, clockwise, using a coin
or a flat edged tool.
5.3 There are four (4) electrical outlets inside the chamber for use with electrical equipment
not exceeding 1 amp.
5.4 Operating Electrical Apparatus Inside Chamber: Place the shaker, roller, spinner,
etc. inside the incubator chamber. Plug apparatus into 1 amp outlet at rear of chamber.
Be sure apparatus draws 1 amp or less (the power switch turns power on & off to outlets
inside chamber).
5.5 Set Main Temperature Controller: Enter desired set point temperature. To enter set
point mode on the controller, press either the Up or Down arrow pad one time. The
digital display will start to blink, going from bright to dim. While blinking, the digital
display is showing the set point. To change the set point, use the Up and Down arrow
pads. If the arrow pads are not pressed for five (5) seconds, the display will stop
blinking and will read the chamber temperature. Note that the Overtemperature
Thermostat should be turned to its maximum position, (clockwise) until the unit has
stabilized at desired set point temperature. Allow the incubator at least 24 hours to
stabilize.
5.6 Calibration: It is recommended that calibration is done once the unit is installed in its
working environment and has been stabile at set point for several hours. Place a
certified reference thermometer in the chamber where it can be easily viewed through
the window. Be certain the thermometer is not touching any shelving. Allow the
temperature to stabilize again until the thermometer reads a constant value for one hour.
Compare the digital display with the reference thermometer. 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 five (5) seconds until the two outside decimal points
begin to flash. While the decimal points are flashing the display can be calibrated by
pressing the Up or Down arrow pads until the display reads the correct value. Allow the
incubator temperature to stabilize again, and recalibrate if necessary.
5.7 Set Overtemperature Thermostat: As mentioned in step 5.2, the Overtemperature
Thermostat should be initially set to its maximum position, to allow the unit to stabilize.
Once the incubator is stabile at the desired set point, turn the Thermostat
counterclockwise until the OVER TEMP light turns on. Next, turn the Thermostat
clockwise just until the light turns off. Then turn the Thermostat clockwise two of the
smallest divisions on its scale past the point where the light went out. This will set the
Overtemperature Thermostat at approximately 1C above Main temperature set point.
