Configures the analog outputs:
Linear 10 V/DEC

Linear output running from 0 to 10 V for each decade.
The following figure shows the linear output voltage
as a function of leak rate.
Log 1 V/DEC

Log output at 1 V per decade. The figure 59 shows the log
output voltage as a function of pressure.

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.
