*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.
*2: When the sensor cable, the transmission cable, or the contact input cable is extended to 30 m or longer, the surge test specified in the EMC directive for CE marking is not applied.
Note
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.
