Note 1:
The standard for effect on the reading by the electromagnetic field of the radiated radio frequency and by the conducted interference is within the measured dissolved oxygen value ± 0.4 mg/L.

Note 2:
When the sensor cable, the transmission cable, or the contact input cable is extended by 30 m or more, the surge test under the EMC Directive for CE marking is not applied.

Note 3:
An arrester (spark over voltage: 400 V) is implemented for transmission output, contact input, and communication. However, use a most suitable surge absorption element on the connection lines in accordance with the ambient environment, the situation of equipment installed, and the externally connected equipment.
