CALIBRATION
As with all pre-calibrated meters, it is highly recommended, even if not
required by regulations, that the user periodically verify the performance of the
meter by running standards with a predetermined concentration. Results
outside of specification are an indication that the meter needs to be adjusted.
This can be done following the user calibration described on page 31. If the
user calibration fails to properly adjust the meter then the meter should be
returned to LaMotte Company for recalibration. (See page 5).
