7. The incubator automatically reverts to the display mode.
Note:
It is important to accurately measure the temperature inside the incubator when calibrating the
temperature. Particularly, the temperature gauge used must have an accuracy of JIS 0.5 Class or better.
The temperature must be measured at several points.
The temperature setting must not change by more than ±1.0
