BASIC PARAMETERS
3. Input each parameter. Press Apply key to save
the input value. The display returns to the Menu
screen.
●Each 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. By holding CO
2
Density slide key and sliding it to the
right, CO
2
density control turns to ON. Settable range: 0.0 %～20.0 %, factory setting: 0.0 % (OFF).
・O
2
Density: Set value of chamber CO
2
density. By holding O
2
Density slide key and sliding it to the right,
O
2
density control turns to ON. Settable range: 1.0 %～18.0 % and 22.0 %～80.0 %, factory setting:
20.0 % (OFF).
・High Limit: The high limit temperature alarm is different from the Automatic set temperature alarm (page
46～47), 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 91～94 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 and O
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 and the Present O
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, the CO
2
sensor and the O
2
sensor are stable
after setting the chamber temperature to the desired temperature, the CO
2
density to 0 % and the O
2
density to 20 %. Then change the setting to the desired CO
2
density and O
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.
