To increase the temperature, turn
the adjustment screw clockwise.
To decrease the temperature, turn the
adjustment screw anti-clockwise. Make the
adjustments in stages, a ¼ turn at a time.
After each adjustment, leave the incubator to
stabilise for at least 30 minutes. The complete
recalibration procedure may take several
hours.
Once the incubator has been
recalibrated to read between 43.5 and
44.5°C, leave it switched on for at least 3 hours.
Take note of the temperature at 30 minute
intervals to ensure that the temperature is
stable.
The following day, switch on the
incubator and allow it to reach a stable
temperature. If the temperature is not within
the correct limit, repeat the recalibration
process detailed in
