7.1.2 Measuring range switch-over
The Mycom CLM 152 has two options for
switching over measuring ranges:
• external remote measuring range
switch-over
• automatic internal measuring range
switch-over (internal measuring range
switch-over only possible in Conductivity
mode in single-circuit mode).
External remote measuring range switch-over
The measuring range can be switched over
remotely by external contacts, e.g. a PLC.
This requires the FCXI expansion module
(electrical connection see chapter 4.4.1).
You can select up to four measuring ranges.

Two-circuit instruments are
permanently configured as
differential measuring instruments:
Current output 1: differential
Current output 2: Cond. 1, Cond. 2,
Switch-over affects:
• Current output
• Limit contactor
• Temperature compensation type
• Substance selection (for concentration
measurement)
The configuration has to be set by the user for
each measuring range (MR1 ... MR 4) in the
corresponding menu.
