Note
- Note 1 : The decimal point position changes automatically
- Note 2 : The actual limit of measuring range of raw conductivity is 500 mS/cm for 0.1/cm and 2000 mS/cm for 1/cm sensor. (The sensor durability for chemicals is not assumed.)
- Note 3 : 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 4 : 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.
