Maintenance

In order to obtain the best measurement results, regular maintenance
and maintenance are required. Maintenance and maintenance include
cleaning of electrodes, checking for damage, etc.
Maintenance work Maintenance frequency
Visual inspection per month
Check Calibration Monthly (depending on usage environment conditions)
Replace electrodes Yearly (according to usage environment conditions)
Phenomenon Approach
Electrodes cannot
communicate
1. Check whether the electrode wiring is correct
2. Check the communication setting parameters (address,
baud rate, parity bit, stop bit)
The measured
value is not normal
1. Check whether the electrode platinum ring is clean and
whether the sensor is damaged
2. Restore the electrode to the factory calibration value,
clean and re-calibrate with standard buffer
3. Check the service life of the electrode
