Zero calibration.
When display shows “1) Zero” press “E” to enter into zero calbration procedure. Display shows:
R 1.00Cl
C 0.00Cl
To calibrate it , if you are using an ECL4-6-7 probe, close water’s flow and wait for some minutes. If you are using an ECL1-
2-3-8 probe use flow-water without chlorine into probe holder or install an activated-carbon cartridge. If no one of these
methods is vailable, unscrew top probe connector or, if not present, disconnect probe’s green wire (signal wire). Wait until “R”
value is stable.
ATTENTION: IT IS NOT NECESSARY THAT “R” VALUE WILL BE THE SAME OF “C” VALUE.

Slope calibration.
When display shows “2) Slope” press “E” to enter into slope calbration procedure. Display shows:
R 1.00Cl
C 0.00Cl
To obtain reliable reading results is necessary to calibrate the probe using a chlorine solution. Verify the plant’s chlorine value at
the end of probe holder using a colorimetric (DPD1) analysis sistem. Using “UP” and “DOWN” keys enter this value in “C” field.
Wait until “R” value is stable.
ATTENTION: IT IS NOT NECESSARY THAT “R” VALUE WILL BE THE SAME OF “C” VALUE.
