Before starting calibration, make sure you are in the correct measurement mode. When you 

switch on the meter, the meter begins with the units you shut it off in.  

 

For best results, select a standard value close to the sample value you are measuring. 

Alternatively use a calibration solution value that is approximately 2/3 the full-scale value of 

the measurement range you plan to use.  For example, in the 0 to 1999 

µS conductivity range, 

use a 1413 

µS solution for calibration.  

 

Do not reuse calibration solutions after calibration. Contaminants in the solution can affect the 

calibration, and eventually the accuracy of the measurements. Use fresh calibration solution 

each time you calibrate your meter.  

NOTE: Your meter is factory set to a temperature coefficient of 2.1% per 

°C. For most 

applications this will provide good results.  See Program P5.1 on page 34 to set the 

temperature coefficient to different value. See Addendum 3, “Calculating Temperature 

Coefficients” to determine the appropriate temperature coefficient for your solution.  

NOTE: The factory default value for normalization temperature is 25 

°C. If you need to 

normalize to a value other than 25 

°C, see Program P5.2 on page 35.
