Calibration

Press 

CAL

 to enter calibration. The “CAL” tag and the 

recognized  standard  value  will  appear  on  the  third 
LCD line. If necessary, press the ARROW keys to select 
a diff erent standard value. The “ “  along with “STIR” 
tag will be displayed and “WAIT” will blink on the LCD 
until the reading is stable.

When the reading is stable and close to the selected 
standard, “CFM” tag will blink, the message “ SOL STD” 
and the value will be displayed.

Press 

CFM

  to  confi rm  calibration.  The  instrument 

displays  “SAVING”,  stores  the  calibration  values  and 
returns to measurement mode.

Conductivity vs Temperature Chart

The following table lists the temperature dependence of Hanna EC calibration 
standards. edge

EC

 ® uses these values and their temperature coeffi

    cients during 

calibration.
