Maintenance
The LMS 120 is a maintenance-free monitoring device and does not need periodic maintenance or inspection. As
part of a district heating maintenance programme inspections should be carried out at least once a month.
The
and
displays indicate any errors. If one of these displays lights up, the
measurement values should be inspected.
The record from Section 6.2. Fault record on page 16 should be used for a service report.
