9. Maintenance

Generally speaking, under normal operation, the transmitter needs no maintenance

except regular cleaning and calibration of the electrode to ensure accurate and stable

measurement and system operation.

The cleaning cycle for the electrode depends on the pollution degree of the

measurement sample. Normally, it is recommended to make weekly cleaning. Consult

your electrode instruction manual for detailed cleaning and care directions.
