Each parameter setting
·
Temperature: Set value of chamber temperature.
Settable range: 0.0
o
C~50.0
o
C, factory setting: 37.0
o
C.
·
CO
2
Density: Set value of chamber CO
2
density.
Settable range: 0.0 %~20.0 %, factory setting: 0.0 %.
·
High Limit: The high limit temperature alarm is different from the Automatic set temperature alarm (page
39), and it is independent temperature alarm. In case the chamber temperature exceeds the temperature
of the high limit temperature alarm, this alarm is activated.
Settable range: 20.0
o
C~53.0
o
C, factory setting: 53.0
o
C.
Refer to page 88 for detail of each alarm.
Note:
·
When changing the set temperature from less than 45.0
o
C to 45.0
o
C or higher, the incubator readjusts
the CO
2
sensor. During readjusting, “Status: Gas sensor initializing” is displayed in the Message display
field, and “--.-” is displayed in the Present CO
2
density display field. After 15 minutes in the shortest, the
incubator returns to the normal operation.
·
When operating the incubator for the first time or after not using it for an extended period of time, operate
it for at least about 4 hours until the chamber temperature and the CO
2
sensor are stable after setting the
chamber temperature to the desired temperature and setting the CO
2
density to 0 %. Then change the
setting to the desired CO
2
density.
·
Set the temperature of the high limit temperature alarm after the chamber temperature is stable at the set
value.
·
Set the high limit temperature alarm to at least 1
o
C higher than the chamber set temperature.
