Conductivity:
Automatic measuring range switch:
measuring ranges:
The switch points of the measuring ranges in the
display are not identical to the switch points in the
microelectronics (depending on the cell constants
and the temperature)
salt content:
Temperature measuring range of conductivity
probes
(Refer to "Temperature" on p. 58 for accuracy):
Using suitable adapter cables the 4mm socket or
the TRIAX socket can be used (see "pH values" for
measuring ranges). The instrument must be set at
combined mode (pH and conductivity) so that the
connections in the pH range can be checked for
temperature sensors if the temperature sensor is
not available in the conductivity probe. These can
also be used for temperature compensation in the
conductivity measurement.
