The intrinsic uncertainty is the error specified for the reference conditions.
The operating uncertainty includes the intrinsic uncertainty plus variations of the quantities of influence (position, supply voltage,
temperature, etc.) as defined in standard IEC-61557.
The uncertainties are expressed in % of the reading (R) and in number of display points (ct):
± (a %R + b ct)
