䋨3䋩 Set the present correct temperature with key and key. Press 㩷 ENT key.

䋨4䋩 The display will automatically revert to the present temperature.

䈀Example䈁 If the internal temperature display shows 37.0㷄䋨the set value䋩and the

actual measured value is 36.8㷄,

㽲㩷 Press㩷 CAL 㩷 key for approx. 5 seconds.

㽳 The “3” (top digit) of temperature display is flashing, other digits will go off.

㽴 Set the displayed value at 36.8㷄 with key and key, then press ENT

key.

㽵 The display will automatically revert to the present temperature.

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

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: In PV display, press CAL key for more than 5seconds to enter the device

into temperature calibration mode. Input a desired function code with

key and key then press ENT key.

F01: UV lamp lighting time set (initial: 0min, settable range:0~30min)

Note) UV lamp is optionally provided.

<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.
