CON 400/410 

- 7 - 

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.

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.  

For information on how to calibrate your meter: 

•  See section 4.3 for Temperature Calibration.   
•  See section 4.4 for Conductivity  
•  See section 4.5 for TDS Calibration (CON 410 meter only).
