the top graph and the Relative

Humidity (42270 only) on the

bottom graph.

• The max, min, mean, and standard

deviation values are shown on the

right side of each graph.

• Use the mouse to adjust the yellow

knobs (left side of Statistics screen

all readings into divisions (up to

130 divisions are possible). This

can also be done by clicking the
