10 ELECTRODE CARE AND MAINTENANCE
Keep the conductivity electrode clean. Rinse the
electrode twice, and gently swirl it while you take
readings. For best accuracy, soak a dry electrode for at
least 5 to 10 minutes or longer before calibration. Rinse
the electrode with de ionised or tap water before
storing. Never scratch the bands with a hard substance.
Do not strike the electrode against any hard surface.
Do not make continuous contact with your solutions.
Readings will rise over a period of time while you soak
your electrode.
Do not immerse the electrode in oily solutions. Clean
the electrode thoroughly by stirring it in a mild detergent
bath or isopropyl alcohol. Wipe the electrode with a soft
tissue paper. Rinse thoroughly in tap water and then in
de ionised water. Recalibrate the meter after cleaning
the electrode.
The conductivity electrode (Order Part No: EC-
CONSEN91W/ 35608-50) which is included with your
meter features a removable electrode guard to make
cleaning easy. This guard must be attached to the
electrode during measurement or calibration.
To remove electrode guard:
1.
Grip yellow electrode guard and twist counter
clockwise. The locking notch will release.
2. Slide electrode guard off end of electrode.
