compensation
Temperature elementPlatinum resistor: 1 kΩ (0℃)
Temperature compensation
  • Temperature characteristic of NaCl (reference temperature: 5℃ to 95 ℃)
  • Arbitrary temperature coefficient input (reference temperature: 5℃ to 95 ℃; temperature coefficient: ±3%/℃)
  • No temperature compensation
    One of the three ways of compensation is selectable.
    (In the de-ionized water area, the temperature compensation for pure water is automatically performed in both NaCl and arbitrary temperature coefficient compensation settings.)
Temperature compensation

0 ℃ to 100 ℃(However, the compensation calculation is extended lower than 0℃ or higher than 100℃.)
Temperature calibration1 point calibration comparing to reference thermometer
CalibrationConductivityBased on parameter input of coefficient for the sensor cell constant.
TDS conversionConversion by user-defined coefficient value (TDS calculation is 0.30 to 1.00 times of sample conductivity by μS/cm.)

*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.
