OPERATION
5.1 Check power supply against unit serial plate; they must match. Plug service cord
into the grounded electrical outlet and turn the power switch ON.
5.2 Thermometer Placement: Place the thermometer and clip (provided in the
accessory kit) through the hole at the top of incubator. The thermometer is to
verify operating temperature. See Figure 3.
5.3 Set Temperature Controller: To set the main temperature controller,
perform the following steps:
1. To enter set point mode on the controller, press either the UP or
DOWN arrow pad one time.
2. The digital display will start to blink, going from bright to dim. While
blinking, the digital display is showing the set point.
3. To change the set point, use the UP and DOWN arrow pads. If the
arrow pads are not pressed in five (5) seconds, the display will stop
blinking and will read the temperature of the unit.
4. Allow the incubator at least 24 hours to stabilize.
5.4 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 your 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.
