B. Closing and Opening the Door
To secure the door, press the door against the cabinet to close and push
down the top lever. To open, press the lower latch release button.
C. Using the Temperature Controller
The oven is equipped with a Watlow EZ-Zone temperature
controller (shown at right). The controller has two LED
displays and five buttons. The upper display shows ACTUAL
temperature inside the chamber. The lower display shows the SET or
programmed temperature. The up and down arrow buttons are used to
adjust the desired temperature and are also used to calibrate the oven.
The advance button (circle icon) at lower left is used to scroll through
parameters during calibration. It is not used during normal operation.
The infinity button (
∞) is used for adjusting the power that is delivered to
the chamber heaters or for exiting calibration mode. It is programmed at
the factory to provide 100% power and should not be adjusted during
normal operation.
The EZ button on the left is for advanced functions not applicable to this
oven model and should not be adjusted during normal operation.
To set oven temperature, simply push the up and down arrows until the
desired temperature is shown in the lower display. The unit will now
adjust the heat of the chamber until the SET temperature is attained.
The controller is calibrated at the factory to provide accurate chamber
temperatures from ambient +5 to 99°C. SciGene recommends checking
calibration monthly. See section F. Calibrating Oven Temperature for
details.
D. Setting Rotator Speed
The rotator is turned on and off and its speed of rotation controlled
through the rotary switch. Turn the dial clockwise from its stopping
point to turn on the rotator drive system and set the speed of rotation.
Rotation speed is adjustable up to 20 RPM.
E. Using the Jog Switch
The jog switch is used to momentarily advance the rotator when the door
is open. When the jog switch is pressed, the rotator will turn at the speed
selected on the speed controller. It will not move if the speed controller
is turned off or is set too low.
