Automatic internal measuring range switch-over
(only with conductivity mode/single-circuit operation mode)
Here the Mycom switches automatically to the
suitable measuring range. This requires the
FCYK expansion module (electrical
connection see chapter 4.4.1).
The current measuring range is signalled via
contacts 3 and 4 to the downstream
evaluation unit.
Note:
The function is activated
automatically when contacts 3 and 4
are programmed as the »MR
switch-over« (see Chapter 7.1.2).
Then you can define the switch-over points in
the Instrument data/Internal MRS menu and
their individual switching hystereses
(LOW and HIGH values).
Example of automatic internal measuring
range switch-over with four measuring ranges:
