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 r1.0
o
C, and the CO
2
density must not change
by more than r1.0% 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 or the CO
2
density by more than 1.0%, perform calibration in several
stages over a period of time.
