In this menu Fig. 6-3 all features that influence the way data are displayed are put
together.
6.2.1 Scale linear/logarithmic
• Main Menu > View > Scale linear/logarithmic
These settings apply to the bargraph (= bar underneath the digital figures in the
measurement mode) and Y-axis in the trend mode.
The scale of the bargraph can either be linear or logarithmic. With the arrows (up and
down) it can be determined how many decades the bargraph covers.
Usually a logarithmic scale is recommended because leak rates may change easily
over several decades.
