LCD DISPLAY DESCRIPTION
• The conductivity value is
displayed on the left side of
the LCD.
• The temperature value is
displayed on the upper right
side of the LCD.
• The total number of records saved is displayed on
the lower right side of the LCD.
CONDUCTIVITY PROBE CALIBRATION
The probe should be calibrated before first use.
• Always use a fresh calibration solution because
contaminants in the solution will affect accuracy.
• Calibrate at 2/3 full range under most conditions.
For example, if the measuring range is 0~1999 mS,
use 1413 µS solution to calibrate.
• You will only need to do single-point calibration.
Calibration Procedure
1. Remove the protective cap from the conductivity probe.
2. Rinse the probe by inserting it into de-mineralized or
distilled water for 30 minutes.

-Press to confirm the
calibration or parameter
