The device regularly performs zero calibration automatically. This
function secures the stability of the measurement value for the
turbidity, the color, and the residual chlorine.
The windows of the turbidity and color sensors accumulate dirt
from sample water. Also, air bubbles and dirt must be removed
since they affect the measurement value. The automatic
cleaning feature periodically uses a wiper to clean the cells.
Keeps some of sample water when a malfunction occurs while
measuring.
Auto draining is a function to regularly remove dirt from the
measurement cell and tubes with air bubbles and water draining
so that measurements remain accurate.
Adjust the clock.
Configure LCD (display) settings.
