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 can not change by more than
± 1.0
o
C during calibration. If these values are
exceeded, an error buzzer will sound, the input data will be ignored, and the Incubator will return to the
display mode. If it is necessary to change the temperature by more than 1.0
o
C, perform calibration in
several stages over a period of time.
