7.2.2 Current output 1 / 2
With single-circuit measurement the
configuration is always as follows:
Current output 1: pH / redox
Current output 2: temperature
With two-circuit measurement (see 7.1.1):
Current output 1: pH / redox (channel 1)
Current output 2: pH / redox (channel 2)
or
temperature
or
diff. (channel 1 – channel 2)
