Before measuring, make sure you read the information
on precautions for using this device and connection
methods. For screen setting details, See the Instruction
Manual (CD-R version).
Check that the power distribution board you are using
has a 400 V three-phase 3-wire configuration.
Measurement
location
Three-phase 3-wire 400 V power line on a distribution board (50
Hz, 50 A load)
Application • To connect the 3196 to the measured power line while viewing
the connection diagram on the screen
• To check whether the connection is correct on the vector screen
• To check the three-phase voltage and three-phase current wave-
forms
• To check the voltage unbalance factor and current unbalance
factor
