2) Clean the cell with pure water
a. Put the tube into water as shown on the left or inject the water with a

total of 20 mL is flushed through the cell.
b. If the optional peristaltic pump is installed, press [PUMP] key to flow
in more than 20 mL water, to flush the cell well. For effective
cleaning, lift up the tip of tube from the water a few times to allow
some air to be pulled in.
Note:
When the measuring cell and tube lines were filled with
ethanol, rinse out ethanol with as much pure water before
measurement is started.

standard.
