4.3 Maintenance
In order to make the turbidity sensor have a good running state, please do the
following basic maintenance as needed:
It is recommended that sensors be calibrated, tested or inspected every 3
months;
It is recommended that every 6 months clean the sensor and circulation pool,
the poor water quality environment can appropriately increase the number of
cleaning;
Keep all maintenance, calibration operation records.
4.4.Field calibration
Turbidity sensors generally recommend users to send products back to
manufacturers using standard liquid for accurate calibration.
At the same time, in order to meet the needs of some users on-site calibration
requirements, this product also provides on-site calibration function, the operation
process is as follows:
Step 1: Press menu key; Step 2: Enter calibration;
