Table 3: Reading offset estimated value: extrapolated values from trend lines equations. Configuration; 35mm Petri Dish adapter, with
Humidifying Module heater. Standard values are pointed out (specimen temperature 37°C.)
Advantages of this approach:
High accuracy
Well suited for expert user
Disadvantage:
Further calibration is needed in case room temperature differs more than +/-2°C
from factory calibration temperature of 23°C.
Offset values are valid only for one Set Point temperature. The Offset values must
be experimentally re-evaluated for each different set point.
If the sample adapter changes, please modify the Offset and re-calibrate the chamber, to
ensure that the sample will be at the correct temperature.
Offset values are evaluated according to the following:
1.
Maintaining sample temperature error within ± 0.3 °C
2.
Avoiding condensation on the lid glass
3.
Improving the gas stream humidity level by adjusting the offset of HM
