NOTE: For the greatest accuracy during the calibration procedure,
be sure that after the meter is blanked and the blank is scanned as a
sample, the reading is 0.00. If not, reblank the meter and scan the blank
again until it reads 0.00. When scanning the calibration standards as
the sample, scan the calibration standard three times removing the
tube from the chamber after each scan and reinserting the tube in the
chamber with the same orientation. The readings should be consistent.
Use the last consistent reading to calibrate the meter. If the readings are
not consistent, avoid using an aberrant reading to calibrate the meter.
ANALYSIS WITHOUT BLANKING PROCEDURE
To obtain the most accurate results the meter should be blanked before
measuring a sample. The blanking step is not as critical for samples
above 10 NTU. The meter should always be blanked before reading
samples below 10 NTU.
