䋨Note䋩
䊶㩷In temperature calibration, it is important to accurately measure the internal temperature.
Particularly, for the thermometer used, its grade of accuracy should be than 0.5 class. The
measure should be carried out at the center of the chamber.
䊶㩷The temperature calibration range is between the set value 㫧1.0㷄. If the value over this
range is input, an error tone will be emitted, the input data will be ignored, and the display
will revert to the present temperature. Therefore, if you need to calibrate more than 1.0㷄,
you should repeat above procedure several times.
㩷 Notes when the unit installation
㩷
㩷
The displayed internal CO
2
is higher than the actual when the internal temperature and
humidity are not stabled (reached) just after the unit started running.
It is not abnormal because the CO
2
sensor is heat conducting type.
After the internal temperature is set to desired value and CO
2
is set to 0%, pour 1.5L distilled
water into the humidifying pan then run the unit for approx. 8hours to be internal temperature
and humidity stabled.
Finally perform CO

<Direction
for use>
Input “F01” on the temperature display then press ENT key to show a present SV
on the CO
2
display. Input the desired value with key and key then press
ENT key to store the value and reverts to PV.
If a value out of the range is input then ENT key is pressed, the buzzer sounds
for a second to keep the previous setting.
<Action> After the door open-and-shut, UV lamp is lit in appointed time then automatically
goes off. There is approx. 3~5seconds delay to active the mode, due the device
would check water level in the humidifying pan just after the door shut.
If the door is opened during UV lamp is lit, the lamp goes off.
F02: UV lamp 24hours sterilization mode set
Note) UV lamp is optionally provided.
<Direction
for use>
Input “F02” on temperature display to show “000” on CO
2
display.
Input “001” with key and key to enter the device into 24hours sterilization
mode.
Press ENT key when “000” is displayed, simply reverts to PV display.
<Action> When 24hours sterilization mode is set in F02, UV lamp is lit and automatically
goes off after 24hours has passed. UV lamp goes off and 24hours sterilization
mode would be cancelled if the door is opened during the sterilization.
If 24hours sterilization mode is reset during the sterilization, it would restart
24hours sterilization mode at the time.
Note) If this mode is set, UV indicator lamp should be lit even if UV lamp is not fitted.
