How the CD611 EC meter works

Remove the black protection and turn on the meter with the ON/OFF button located on top.

Plunge it to the limit and wait for the data to stabilize.

The meter automatically compensates for temperature variations.

After use, rinse the electrode with water to keep it clean.

The data reported on the display must be multiplied by 100 to give a direct reading in mS/cm.

Calibration of the CD611 EC meter.

Immerse the meter up to the limit in EC calibration liquid (M10031)

Wait for the data to stabilize and use the screwdriver to tighten the screw on the back.

Set to 1.4 (multiplied by 100 gives an EC of 1413). The meter is now calibrated.
