Main unit
Accuracy: Class 2
Basic error:
ΔX= K*(X*2%+Y*2%DX)
ΔY= K*(X*2%+Y*2%DY)
ΔX: in-phase component basic error allowable value;
ΔY: orthogonal component basic error allowable value;
K: instrument constant, K=1;
X: in-phase measurement of the absolute value of the dial;
Y: orthogonal measurement of the absolute value of the dial;
DX, DY: minimum dividing or quantifying value of measuring dial
