4 CALIBRATION
4.1 Important Information on Meter Calibration
Your meter has five measuring ranges. You can calibrate one point in each of the measuring
ranges (up to five points). If you are measuring values in more than one range, make sure to
calibrate each of the ranges you are measuring.
To view current calibration points, see SETUP section Program 2.0 on page 28.
The following table lists the corresponding conductivity and TDS ranges. You should calibrate
each range using a solution that falls between the values in the “recommended calibration
solution range” column.

0.00 Æ 19.99 mS 6.00 to 17.00 mS 1.00 Æ 9.99 ppt 3.00 to 8.50 ppt
0.0 Æ 199.9 mS 60.0 to 170.0 mS 10.0 Æ 200 ppt 30.0 to 170 ppt
When you recalibrate your meter, old calibrations are replaced on a range by range basis. For
example, if you previously calibrated your conductivity meter at 1413
μS in the 0 to 1999 μS
range and you recalibrate at 1500 μS (also in the 0 to 1999 μS range), the meter will replace
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 probe, it is best to clear
all calibration data in memory. To erase all the old conductivity and TDS calibration data
completely from memory, see SETUP section Program 8.0 on page 39.
