SETTING THE ALARM TEMPERATURE
Setting the high-temperature alarm
An abnormality (chamber temperature rise) is indicated by the alarm indicator, and the chamber
temperature display blinking, and the buzzer sounding (15 minutes after blinking) if the chamber
temperature exceeds the set value of the high-temperature alarm. Always set the high-temperature alarm
to protect stored items from damage resulting from an increase in temperature.
 Setting range of work temperature for high temperature alarm:
Between 5
o
C and 15
o
C higher than the chamber set temperature
 Initial setting (factory setting): 10
o
C higher than the chamber set temperature
For example, to change the alarm temperature from chamber set temperature plus 10
o
C (i.e. the
high-temperature alarm works at 10
o
C higher than the chamber set temperature) to chamber set
temperature plus 5
o
C (i.e. the high-temperature alarm works at 5
o
C higher than the chamber set
temperature)
(The following is only an example. Choose the actual setting according to the desired alarm
temperature.)
