Analog Output
Configures the analog outputs:
❑
Linear 10 V/DEC
Linear output running from 0 to 10 V for each decade.
Figure 6-4 shows the linear output voltage as a function
of leak rate.
❑
Log 1 V/DEC
Log output at 1 V per decade. Figure 6-5 shows the log
output voltage as a function of pressure.

Bar Graph
Configures the bar graph:
❑
Linear Only
The linear bar graph leak rate appears across the top of
all screens when selected. In the Linear Bar Graph display
mode, the bar graph display represents the mantissa of the
leak rate, spanning from 0 to 10. The numerical display
(located to the upper right of the bar graph) indicates the
leak rate exponent value. This mode offers exceptional
resolution within a decade.
