the intrinsic uncertainty is the error defined under the reference conditions.
the operating uncertainty includes the intrinsic uncertainty plus the effects of variation of the quantities of influence (supply
voltage, temperature, interference, etc.) as defined in standard IEC-61557.

This voltage is displayed only if it exceeds U
L
(25 V, 50 V or 65 V).
Measurements of potential of the voltage probe
The characteristics are the same as in the voltage measurements.
This voltage must normally be between 0 and U
