Conductivity measurement
22
• Setting the temperature conversion (Default: ON, 2.00%/°C
）
The measured value of a sample that is not at 25°C can be converted to a value at 25°C.
The temperature characteristics of the conductivity vary by sample. To use the
temperature conversion function correctly, temperature coefficient (the rate of change
per 1°C of the conductivity) must be set for each sample. The setting of “ Setting the
temperature display (default: ATC) ” (page 18) is applied to the sample temperature
before the conversion. Be sure to set the temperature display setting to automatic
temperature measurement (ATC), or enter the sample temperature correctly.
1. Press the key to enter the setting mode.
2. Press the keys to select the "TC" (temperature conversion setting) and
then press the key.
3. Select "ON" to use this function, or select "OFF" not to use it. And then press
the key.
When "ON" is selected, enter the temperature coefficient and then press the key.
4. Press the key to reflect the change.
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.
