Appendix
Indexing a Sample Vial
The United States Environmental Protection Agency recommends that
the vial used for turbidity calibration or sample measurement be
indexed. Its purpose is to obtain a position which provides the lowest
turbidity reading. The indexing methods are as follows.
1.1 Fill the vial with the distilled water (< 0.5 NTU). Cap the vial.
1.2 Wipe the vial with the lint-free cloth. Ensure that the outside of
vial is clean and dry.
1.3 Place the vial in the measurement chamber. Align the triangle
mark on the vial with the arrow on the meter.
1.4 Press the
Meas
key, the meter begins the measurement.
1.5 Slowly rotate the vial approximately 45°. Close the light shield
lid and record the reading.
1.6 Repeat the step 1.5 until the lowest turbidity reading is shown.
Mark this position on the vial.
