3. Replace the incubator lid with the testing lid and thermometer assembly. The
bulb of the thermometer should be completely immersed in the water.
4. Ensure that the internal battery is completely charged, or that the kit is
operating from a mains electricity supply or well-charged external 12v battery.
Switch on the incubator.
5. Check the temperature of the incubator and observe over a period of 30
minutes to make sure that it has stabilised. The incubator normally takes no
more than 3 hours to reach a stable temperature, depending on the ambient
temperature.
6. Once the incubator has stabilised, if the temperature is between 43.5 and
44.5°C, then recalibration is not necessary and the water may be removed with
tissue or a cloth. If the temperature is not within these limits, follow the
recalibration procedure below.
7.3.2 Procedure for Recalibrating the Incubator
1.
Leave the testing lid and thermometer assembly in place and keep the
incubator switched on.
2. Insert the trimmer tool into the hole
on the side of the unit and locate
the tool in the calibration screw
(blue trim).
Note: Small adjustments of the
screw result in large changes to the
temperature. A quarter turn (90°)
results in a temperature change of
approximately 1°C.
3. To increase the temperature, turn the adjustment screw anti-clockwise. To
decrease the temperature, turn the adjustment screw clockwise. Make the
adjustments in stages, a little at a time. After each adjustment, leave the
incubator to stabilise for at least 30 minutes. The complete recalibration
procedure may take several hours. Be patient.
