CONDUCTIVITY ELECTRODE:
Ensure that the sensor is thoroughly washed with distilled water after each use. If there is a build-up of solids inside the measurement area
of the cell, these should be removed very carefully with a cotton bud soaked in solvent, taking care not to touch the metal parts of the
inner cell.
DISSOLVED OXYGEN PROBE:
Please always keep probe’s membrane moist.
If you do not use the probe for long periods, please screw off membrane cap and rinse the
probe's cathode, anode and the membrane with distilled water, then soak up residual water on them with filter paper, and install the probe.

CAUSE
CORRECTIVE ACTION
Electrode dried out
■
Soak the pH electrode in 3M KCL solution for 10 minutes
■
Soak the Ion Selective Electrode in the diluted standard
solution at least 15 minutes
■
Soak the conductivity electrode in tap water for 10 minutes
Measured value is out of range
■
Check the electrode whether clogged, dirty or broken
Incorrect calibration solutions
■
Use fresh calibration solutions for calibration
Setting value does not match calibration solution
■
Reset the calibration value
DO electrolyte solution is depleted
■
Refilling electrolyte solution
Zero oxygen solution is contaminated
■
Replace the calibration solution
pH electrode is out of service life
■
Replace the pH electrode
Keypad is not working properly
■
Replace the batteries
