Important Information on Meter Calibration
Your meter has five measuring ranges. You have an option of calibrating your meter
in a single point calibration for all the five ranges or for better accuracy; you can
calibrate one point in each of the measuring ranges (up to five points). This selection
of single point calibration and multi point calibration can be set in the SETUP menu
Program P9.2. See page 52 .
The following table lists the corresponding conductivity and TDS ranges. For either
the single or multi point calibration, you should calibrate using a solution that falls
between the values in the “recommended calibration solution range” column.

In single point calibration, when you recalibrate your meter, the old calibration will be
replaced by the new one even if the new calibration is done in a different range from
the old calibration. For example, if you have previously calibrated your conductivity
meter at 1413 µS in 0 to 2000 µS range, and you recalibrate at 12.88 mS in 0 to
20.00 mS range, the new calibration will override the previous calibration in 0 to 2000
uS range.
In the case of multi point calibration, when you recalibrate your meter, old calibrations
are replaced only on a range basis. For example, if you previously calibrated your
conductivity meter at 1413 µS in 0 to 2000 µS range and you recalibrate at 1500 µS
(also in 0 to 2000 µS range), the meter will replace only the old calibration data (1413
µS) in that range. The meter will retain all calibration data in other ranges.
To completely recalibrate your meter, or when you use a replacement electrode, it is
best to clear all calibration data. See page 45 for more information on calibration data
clearance.
