Features
1. Easy operation & smaller installation space
zThis small sized cabinet can be stacked. (548mm of its depth)
zUsable height (only 1725mm height) even if stacked 3 units.
zSelectable right or left-hand door.
(Please consult with your service representative.)
zAir-jacket type is suitable for the maintenance.
zControl panel is fitted on the outer door surface and it has a wide digital display
and a large keypad.
zInside chamber wall made by stainless steel and R corner structure makes
cleaning easier.
2. Internal temperature & internal humidity recovery characteristics
zOriginal Direct Heat & Air (DHA) jacket and PID temperature control system
3. Anti-bacteria SUS
zInside chamber (except for humidifying pan) material is made by anti-bacteria
SUS.
4. A new ROM installed
zA new ROM version installed to set Communication system optionally.
5. Validation
zDisplay Zero Adjustment and Span Adjustment can be operated on the control
panel.

Temperature calibration
䋨1䋩Press CAL key for approx. 5 seconds.
䋨2䋩The top (the 3
rd
) digit of temperature display is flashing, other digits will go off.
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
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
2
zero setting and CO
2
span setting.
Note) When Key Lock is ON, calibration mode is disabled.
