About measurement
(1) A class index is a rated-frequency 50/60Hz ±10％ value. Linearity is within ±0.3％.
(2) In ±10％ of rated frequencies, current, voltage, power, and reactive power are normally measured, in case
the voltage between input lines is 10V or more. If the voltage between input lines is 60V or more, it is
measurable to the frequency of 168Hz. (However, outside of an accuracy guarantee)
(3) In case the voltage between input lines is 30V or more, frequency is measured normally.
Note(
６
) The critical value of measuring range constitutes the following.
Current：0～120％ of measuring range
Voltage：0～156V(3-phase 3-wire)，0～156/√ 3V(3-phase 4-wire)
［Measures to +30％ at the 120V(120/√ 3V) cases of rating］
Active power (One-side swing)：-20～+120％ of measuring range，
Active power (Both swing)，Reactive power：-120～+120％ of measuring range.
７
Note(
) In case current, power, and reactive power measure the next inverter output directly, an error becomes
large. Cycle control, SCR phase angle control, PWM control.
８
Note(
) S phase current of 3-phase 3-wire is for 2CT input, calculates in R phase and T phase current combination.
And, TR line voltage is for 2VT input, calculates in RS and ST line voltage combination.
