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