Put the CLEAN (DI water or NaOH liquor), press ‘ENER’ key , the instrument starts to absorb the
CLEAN;
Press ‘CLEAN’ key to clean again if one time is not enough, it can clean for many times;
Press the ‘’
↓
’ to stepwise ‘Absorb clean liquor” to enter next step directly if it needn’t cleaning;
Press ‘MENU’ key back to the main menu.
2. Absorb DI water
The system will automatically enter the “Absorb DI water” interface to test absorbance if test items
with END-point method, the screen will display:
Put DI water, and press ‘ENTER’ key, the instrument starts to absorb DI water and test absorbance.
It will prompt you to absorb DI water after filter-wheel rotated in order to adjust absorbance.
3. Absorb clean liquor
When you test the item for the first time, you need to do Blank Test and Standard Test, the system will
enter into “absorb clean liquor” interface automatically after finishing cleaning or finishing absorbance
test.
Put clean liquor, press “ENTER” key, the instrument starts to absorb clean liquor,it will test the
absorbance and original value of Blank liquor, the test result will be shown in the chart.
