*1: Only the sanitary sensor (FS-01 series) is applied.
*2: Conductivity measurement and TDS conversion measurement cannot be selected at the same time.
*3: 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.
