In order to keep the output voltage within the indicated precision range, a recalibration may be necessary, following a long period of use.
(3)
If the mains frequency is within ± 5% of the selected value, the UPS is synchronised with the mains. If the frequency is out of the tolerance
range, or in battery operation, the frequency will be the se0.01%
