* Heavy-line circular arc on the scale indicates the primary effective
measuring ranges. (guaranteed accuracy range)
<Operating error>
Operating error (B) is an error obtained under the nominal
operating conditions, and calculated with the intrinsic error (A),
which is an error of the instrument used, and the error (En) due to
variations. According to IEC61557, the maximum operating error
should be within +/-30%.
