㻌Temperature calibration 㻌

Here is the explanation how to calibrate chamber temperature.
Ex) When setting temperature is 37.0䉝and actual temperature is 36.5䉝
Process Operation MENU
0 Set thermal sensor at the center of the chamber and start the unit running.
Leave it until chamber temperature is stable.
1 Press MENU key in Top screen to call MENU screen. Select Tools. Tools
2 Select Tools (1/2) screen is displayed. Select Temp/CO2Calibration.
3 Temp/CO2Calibration is displayed and press MENU key to activate MENU key. Select
OK and press ENTER key.
OK
4 Change the value in the column Temp Span to 36.5
䉝
by pressing digit shift key and
numerical value shift key.
5 Press MENU key to call MENU screen. Select OK and press ENTER key. OK
6 Automatically reverts to Select Tools㻌(1/2) screen.
*Note (1) It is important to have an accuracy in thermal sensor when measuring center temperature of
the chamber.
(2) Input range:1.0䉝~ 䇲1.0䉝. It is unacceptable to input over the range at once.

CO2span calibration
(Ex䠅When setting CO2density is 5.0% and actual CO2density is 4.5%:
Process Operation MENU
1 Put densitometer thorough the sample port at the front side of the unit to measure
chamber CO2 density.
2 Select Tools in the Top Screen. Tools
3 Select Tools (1/2) is displayed. Select temp / CO2Calibration and press OK key. OK
4 By pressing digit shift key and numerical value shift key, input actual CO2density
䠄4.5%䠅in the column CO2Span. Select OK and press ENTER key.
OK
5 Automatically reverts to Select Tools (1/2) screen.
*Note㻌(1) Input range: +1.0% ~ -1.0% (per input).
(2) Repeat CO2 calibration for several times until displayed CO2 density will match with
actual density.
(3) It is permitted to commence CO2 span calibration only when setting CO2 density is 5.0䠂.
