Calibration of conductivity is not required for this unit as it is factory calibrated.

However; if you wish to calibrate the unit follow the instructions below.

YOU MUST CLEAN THE PROBE BEFORE

CALIBRATING.

See section 2.0.

Rinse probe in fresh water and place it in a known

standard solution. See chart below for the correct

solution.

Wait for reading to stabilize.

Hold down the cal button for 3 seconds until CAL

appears.

Release button and CAL P should be displayed. If Err

is displayed check the probe is clean and that the

calibration solution is fresh and uncontaminated.

A check mark will appear on the screen to indicate that

the calibration was successful. The check mark will

disappear after 30 days. To reset back to factory default

remove/replace battery.

NOTE: If you need to test or calibrate in a 1500 ppm

solution, you MUST set the pen to EC, then multiply your

result by 540. If calibrating, multiply 2.8 by 540

(2.8 x 540 = 1512).

This unit DOES NOT measure in the 540 ppm scale.
