NOTE: The meter will remember the last scanned blank reading. It is not necessary to
scan a blank each time the test is performed. To use the previous blank reading, instead
of scanning a new one, scroll to Scan Sample and proceed. For the most accurate
results, the meter should be blanked before each test and the same tube should be
used for the blank and the reacted sample.
NOTE: For the best possible results, carry a reagent blank through the procedure.
After scanning the blank, perform the test procedure on clear, colorless, distilled or
deioized water. Subtract results of regent blank from all subsequent test results.
CALIBRATION
The calibration should be done with a distilled or deionized water blank and one
standard of known concentration. The concentration of the calibration standard should
be similar to the expected concentration of the sample that will be tested.
PROCEDURE
1. Press and briefly hold to turn
the meter on. The LaMotte logo screen
will appear for about 3 seconds and the
Main Menu will appear.
