• Remove the protective cap and immerse the tip of the probe in the sample to
be tested.
• Stir gently and wait for a stability tag to disappear.
• The electrode automatically compensates for temperature variations.
• The reading on display is directly expressed in: mS/cm or ppm.
• For best results, recalibrate periodically.
• After use rinse the probe with water.
• Always replace the protective cap after each use.
