Temperature
compensation

Applicable temperature
element

Platinum resistor: 1 kΩ (0℃)

Compensation method

• 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
range

0℃ to 100℃ (However, the compensation calculation is extended lower than 0℃ or higher than 100℃.)

Calibration

Resistivity

Based on parameter input of coefficient for the sensor cell constant.

Temperature

Comparison to the accurate thermometer
Both deviation and coefficient of RTD are taken into account for calibration.

Other function

UPW standard resistivity input

Select one from the next.
182.3 kΩ•m (standard), 181.8 kΩ•m, 182.4 kΩ•m,
18.23 MΩ•cm (standard), 18.18 MΩ•cm, or 18.24 MΩ•cm

Clipping function

If the measured value exceeds the user setting value for clipping, the measured data will be held at the clipping value.
