    intrinsic error cophase component ΔX=±(X×2%＋Y×2%)±Dx(Level 1 is optional)
    orthogonal component ΔY=±(X×2%＋Y×2%)±Dy(Level 1 is optional)
    "X"、"Y"——Display value of instrument
    "Dx,Dy"——Display value of instrument
    Dx=2，Dy=5
    dial indicator PETS2(Level 1 is optional)
    working range electricity (1%～149%)In (In =5A)
    (5%～149%)In (In =1A)
    voltage (5%～149%)Un (Un =100V，150V，100V/)
    (5%～149%)Un (Un =100V/3)
    workload electricity TO to TX＜0.12Ω cosΦ=1
    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 polarity indication.
    Note: if it is more than 10% of the rated operating current (voltage), there is still no proper polarity indication, indicating a fault. Please do not increase the current (voltage) to avoid burning out the instrument.
    Variable ratio error indication When the operating current (voltage) reaches more than 5% of the rated current (voltage) and the error exceeds 30% but is less than 180%, the error indication of variable ratio should be given.
