My Truncheon Meter measures lower than expected! Why?

A. If a Truncheon Meter reads low....it only needs cleaning and checking in a known solution. The use of a non scented liquid scourer is used as the cleaning medium to clean the probe face. Please follow the cleaning procedure as laid down in your instruction manual. Never touch the probe face after cleaning as this will cause probe contamination and lower the readings.

Allow time for the Truncheon Meter to adjust to the temperature of the standard conductivity solution (known standard) being measured. If the Truncheon Meter is warmer than the conductivity solution, it will measure lower than expected. Allow up to approximately 10 minutes for temperature equalisation to take place.

Always use a conductivity solution that is fresh and of known quality. The Bluelab CF27.7 conductivity solution is ideal. Always replace the cap on the conductivity solution straight after use. Dispose of any conductivity solution 2 months after first opening.
