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.
The device is not designed to operate when the charger is connected. The measurements must be made using the battery.
