IS 12 / IGA 12 Manual Introduction 11
*Additional measurement uncertainty due to offset drift of the signal converter at long
temperature ranges. Tc = measuring temperature up to which an additional measurement
uncertainty occurs when the ambient temperature differs from the reference temperature of
23 °C
