stored approximately 17 hours ago (1 dot = 1 hour). The v ertical axis of the graph
represents the relative change from one hour to the ne xt.
• When the relative change from one hour to the ne xt exceeds +10.0° C (+18.0° F), the
dot at the highest point for the applicab le hour flashes.
• When the relative change from one hour to the ne xt exceeds –10.0°C (–18.0 ° F),
there is no dot in the applicable hour’ s column.
