If a measuring range is exceeded, AutoRange causes the measuring
instrument to change automatically to the next measuring range.
The function is permanently switched on (display shows ARng).
The fluid temperature is automatically measured by the integrated
temperature sensor of the conductivity sensor (display shows TP).
The measuring instrument automatically recognizes the type of
temperature sensor used. You can connect sensors with NTC30 or
