Theconductance(1/R)isproportionaltothespecicconductivityandaconstantfactorthat
is determined by the geometry of the sensor (length divided by surface area of the hole in the
toroid) and the installation of the sensor.

n Changing the settings
If any setting is accidentally changed, values to the right of the relevant arrow in Table 6 are all
initialized.
