Conductivity measurement

Note

・

The temperature coefficient varies by sample. Before using the temperature conversion

function, always check the temperature coefficient of the sample and set it in the
instrument.

・

When the temperature conversion function is used with automatic temperature

measurement (ATC), deviations may occur within the accuracy of the temperature sensor.
For more accurate measurement, set the temperature setting to manual temperature
display (MTC), and measure using a temperature controlled bath.
