 Basic error

In-phase component

ΔX = ± (X × 2% ＋ Y × 2%) ± Dx (with 1 level optional)

Orthogonal component

ΔY = ± (X × 2% ＋ Y × 2%) ± Dy (with 1 level optional)

"X", "Y"-display value of the instrument

"Dx, Dy" —— Instrument quantization error

Dx = 2, Dy = 5

Voltage

a to x＜0.25VA (100V)

 Polarity error indication

When the operating current (voltage) reaches more than 5% of the rated current (voltage) and the error exceeds 180%, there should be a polarity indication.

Note: If it is more than 10% of the rated operating current (voltage), the polarity indication should not appear, indicating that there is a fault, please do not increase the current (voltage), so as not to burn the instrument.

Ratio error indication

When the operating current (voltage) reaches more than 5% of the rated current (voltage) and the error exceeds 30% but less than 180%, there should be a ratio error indication.
