SE – Error Mode
SE parameterizes the behaviour of the switching outputs Q1 and Q2 and of the
analogue output QA in case of erroneous measurements, as well as the device
state after carrying out a single measurement.

user is responsible to set the correct parameterization.
Q1/Q2 – Switching output
Commands Q1/Q2 parameterizes the behaviour of the switching outputs Q1
or Q2 (see text and diagram of the switching behaviour in chapter 5.3). It can
be parameterized the start w of the measurement range when the output
switches, the length x of the measurement range and the hysteresis y and the
logical behaviour z.
