2) Range changes depending on the substance to be measured
16.2 Signal transmission to the controller
The measuring range and performance characteristics
depend on the installed sensor (see the instructions for use
for the installed sensor).
Frequency of measurement calculation: 1 x per second
(update of display, analog interface and relays).
