The MMD 98RCM mobile measuring case records all voltage
quality parameters and logs this data as single-, three- or fourphase measurement in the low-voltage network (230/400 VAC) in distribution networks in transformer stations, switchgears
and as direct consumption measurement on machines and in buildings. 
The heart of the system is a built-in UMD 98RCM in an IP65 plastic housing.
The device uses the PQ S and GO firmware modules to map all voltage quality functions according to EN 50160.
