NOTE
The liability for defects is only valid if maintenance work is performed
as specified.
Adhere to the appropriate standards, regulations and locally applicable
guidelines.
Check for tightness
(daily)
Check the entire measuring device including all screw connections for
leakage. Repair any leakage points immediately!
Important: Air bubbles in the cell body influence the measuring
accuracy. The cause must be determined and remedied.
Check the cell sand
(weekly)
Check that there is sufficient sand in the cell body. The cell sand must
be swirled around in the bottom section of the cell body. The cell sand
is necessary for cleaning the electrodes of the chlorine sensor and
must be replenished or replaced when required.
NOTE
When fresh sand is replenished, the electrode current can increase
slightly for approximately 2 to 3 hours. During this time do not perform
any calibration.
