(2) Electrode constant setting
To set resistance values that are not affected by the electrode shape, set in this
meter the electrode constants used in measurement and measure resistance as
volume resistivity of a liquid sample.
[Note] Refer to the instruction manual of the liquid sample electrode for more information
about electrode constants. The volume resistivity is calculated by multiplying a
measured value by an electrode constant as follows.
Volume resistivity ρ v = K·measured value [ Ω ·cm]
Where ρ v : volume resistivity in [ Ω ·cm]
K : electrode constant in [cm]
The meter is capable of automatically calculating volume resistivity.
Set an electrode constant as follows.
On the screen illustrated in Fig. 6.6, press the [F5] ACTL key.
The screen will change to the Electrode Constant Setting screen illustrated in Fig. 6.10.
Input the electrode constant of the electrode to be used.
Press the [ENTER] key after finishing setting.
The screen will return to the measurement screen. Select “volume resistivity” [Rv] by
pressing the F2 [MODE] key as the measuring mode. (Displayed measured values will
be the same values as those of [Rv] values even when [Rs] is selected.)

Press the [ENTER] key to use constants on the screen set before returning to the
measurement screen. The concept of electrode constant setting explained in 6.3.3 2)
“Electrode constant setting” and 6.4 “Measuring Liquid Sample” is illustrated below.
