The unit such as k or M is switched automatically.
- The unit of voltage is switched to 1.000kV if exceeding 999.9V.
- The unit of effective power is switched to 1.000MW if exceeding 999.9kW.
- The unit of effective power is switched to -1.000MW if becoming lower than -999.9kW.
- The unit of reactive power is switched to 1.000Mvar if exceeding 999.9kvar.
- The unit of reactive power is switched to -1.000Mvar if becoming lower than -999.9kvar.
- The unit of integrated effective power is switched to 1000.00MWh if exceeding 999999kWh.
- The unit of integrated reactive power is switched to 1000.00MWvar if exceeding 999999kWvar.
- The unit of calculated value is switched to 1000.00k if exceeding 999999 and 1000.00M if exceeding 999999k.
Although the indication value of the model KM-N3 main unit is returned to zero when the integrated value has reached the
maximum, the unit continues to integrate the measured value. Correct values can be obtained by using the communication
function.
Voltage A: The phase voltage and line voltage of the each phase and wire type are displayed.
Voltage B: The line voltage is displayed only for the three-phase four-wire type.
