Rinse a clean tube (0260) three
times with the blank. If samples are
expected to read below 1 NTU the
meter should be blanked with a 0
NTU Primary Standard or prepared
turbidity-free (<0.1 NTU) water. For
the most accurate results, use the
same tube for the blank and the
sample.
6.
Fill the tube to the fill line with the
blank. Pour the blank down the inside
of the tube to avoid creating bubbles.
Cap the tube.
7.
Wipe the tube thoroughly with a lint-
free cloth.
8.
Open the meter lid. Insert the tube
into the chamber. Align the index line
on the tube with the index arrow on
the meter. Close the lid.
