. Measuring the backup time
44
(3) Calculate the initial value of the backup time for the total capacity of the connected devices from
the graph below.
●
Graph of backup time (graph of initial values for products that have not been used at 20°C)
The backup time becomes shorter than the graph (table) below when temperature is lower.
●
The smaller the capacity of connected devices becomes, the longer the backup time becomes.
