6.1  Important Information on Conductivity/TDS Monitor Calibration 
This monitor has ±30% adjustment. Adjustable in 0.1 mS increments. Choose a 
calibration standard that is close to your working solution.  
Calibration should be performed regularly to ensure accuracy. Frequency of 
calibration will vary and should be checked regularly until the required schedule has 
been determined.  
Do not reuse calibration solutions after calibration. Dispose of any used calibration 
solution. Contaminants in the solution can affect the calibration, and eventually the 
accuracy of the measurements.  
NOTE: All new calibration data will over-ride existing calibration data. Minimum 
calibration value is 2.5 mS.  
Adjustments and Minimum Calibration Value are according to specific conductivity 
meter model:
