Important Information on Meter Calibration

The COND 6+ and TDS 6+ have five measuring ranges listed below. Each range can be
calibrated to one point per range (five total points if each range is calibrated). Calibration
is recommended for each range that will be utilized.

The Salt 6+ meter uses a special algorithm for the measurement of sodium chloride
concentration. A one-point calibration anywhere in the measurement range is all that is
needed to achieve specified accuracies for the entire measurement range.

New calibrations replace old calibrations on a per range basis. For example, if the meter
has been calibrated with 1413 µS/cm (0 to 2000 µS/cm range) and a calibration is
performed with 1500 µS/cm (also 0 to 2000 µS/cm range), the meter will replace the
1413 µS/cm calibration in that range. The meter will retain all calibration data in other
ranges.

When the electrode is replaced, it is best to clear all calibration data. To erase all
calibration data completely, see Section 5.8 Restore Factory Default Values.
