Added value through additional functions
UMG 104
he UMG 104 goes far beyond the limits of digital multifunction
T
measurement devices thanks to the integration of additional
functions:
• Multifunction measurement device
• State monitoring
• Data logger
• Meters (kWh, kvarh)
• Temperature monitoring
• Harmonics analyser
Fig.: Large measurement data memory
Due to the four current and voltage inputs there are also
particular advantages with the monitoring of up to four singlephase outputs, e.g. in data centres, offices or single-phase motor
outputs.
