DO RUNTIME CAL: screen (Figure 27) — lets you manually initiate a Runtime

Calculation test to calibrate the internal measurements, which should result in

more accurate runtime estimates. This needs to be done once every 6 months, or

when the connected load changes signiﬁcantly in size. Once initiated, the unit will

operate on battery power until a low battery condition is reached.
