5.4 Correction via Link2sc
The Link2sc procedure offers a secure method of data exchange between process probes and
Link2sc-compatible photometers using an SD memory card or via a local area network (LAN).
During a pure control measurement, the measurement data is transferred from the probe to the
photometer where it is then archived together with the photometric reference data that has been
recorded.
Refer to the Link2sc user manual for a detailed description of the Link2sc procedure.
5.5 Data logging
The SC Controller provides one data log and one event log for each instrument. The data log stores
the measurement data at selected intervals. The event log stores different types of events that occur
on the devices (i.e., configuration changes, alarms and warning conditions).
The data log and the event log can be saved. Refer to the SC Controller user manual for instructions.
