5.6 Resistivity sensor k factor 

The 

smart

CHEM

-C 

automatically recognises whether a k=0.1, k=1.0 or k=10 Resistivity sensor is 

being used via links in the connector. 

Calibration settings for the various k factors are stored separately. The 

smart

CHEM

-C 

does not 

require re-calibration when a different k factor sensor is connected, provided it has already been 
calibrated for the different sensor. A “ 

∗∗

 ” is shown in place of the decimal point if the reading is 

not calibrated or if a past calibration has failed.
