8.1 Resolution of measuring data

The resolution of measuring data is determined as follows according to the rating settings (phase wire system, primary current and
primary voltage).
■Voltage, harmonic voltage RMS
Primary voltage setting
less than 300V
300V ~ 3000V
3000V ~
■Harmonic voltage/ Harmonic voltage distortion ratio,
1 decimal places：0.1%
■power, power demand, reactive power, apparent power
Total load power
less than 12kW
12 kW ~ 120 kW
120 kW ~ 1200 kW
1200 kW ~ 12000 kW
12000 kW ~ 120000 kW
120000kW ~
■Electric energy(expansion), reactive energy（expansion）
Total load power
less than 12kW
12 kW o ~ 120 kW
120 kW ~ 1200 kW
1200 kW ~ 12000 kW
12000 kW ~ 120000 kW
120000kW ~
Note: Extended electric energy is the data of lower three digits
more than electric energy data.
response data is the same as the amount of electric energy
data.
■Electric energy converted value
The Unit depends on setting value.
Total load power
less than 12kW
12 kW ~ 120 kW
120 kW o ~ 1200 kW
1200 kW ~ 12000 kW
12000 kW ~ 120000 kW
120000kW ~ 1200000kW
1200000kW ~
■Pulse converted value
The Unit depends on setting value.
Total load power
0.001 ~ 0.01
0.01 ~ 0.1
0.1 ~ 1.0
