3.1 General Reference Conditions

Quantity of Influence
Temperature
Relative humidity
Frequency
Supply voltage
Electric field
Magnetic field
■ 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.
In this section, uncertainties are typically expressed as % of the reading (R) plus number of display counts
(ct).
