3.3.9 Calibration (Fig 1.8)
In this mode the incubator is calibrated.
To calibrate the unit the following equipment is required:
- Digital thermometer with 100mm x 4mm stainless steel probe
(Included)
- Trace2o® Incubator calibration pack (Included)
- Petri-Lok® Petri-dish cassette
- 10 Aluminium Petri dishes
Assemble the cassette as follows (Fig 3.1):
- Place 10 empty Petri dishes into the bottom of the cassette
- Then place the calibration pack into the cassette
- Fit the spring loaded top and insert the thermometer through the hole in the top. The
thermometer will protrude by approximately 30mm when fully inserted
Fit the cassette into the incubator chamber.
Set the incubator to the desired mode of operation (37/44/User) and start the incubation cycle.
Wait at least 1 hour.
Compare the displayed temperature on the incubator screen to that shown on the thermometer.
If there is a difference > 0.2°C the calibration should be adjusted as follows:
Exit the run mode and step through the screens until the calibration screen is displayed. Press the
middle switch to enter calibration mode. The following screen will be displayed:
Adjust the temperature up or down using the left and right switches until it matches the
temperature displayed on the thermometer. Press the middle switch to save the settings.
Step through the screens until the mode previously used for calibration is displayed and start the
incubation cycle again.
Allow the incubator time to adjust the temperature which could take up to 30 mins and check the
calibration again. If the original temperature was significantly different to the thermometer then
the calibration steps may need to be repeated two or three times.
