3.1.4 Output Control

Press Output Control and the Output Control screen appears (Figure 3-8).
❑
Use this screen to select the desired leak rate output, and Bar Graph display mode.

Linear 10 V/DEC
❑
Linear output running from 0 to 10 V for each decade.
Figure 3-9 shows the linear output voltage as a function
of leak rate.
Log 1 V/DEC
❑
Log output at 1 V per decade. Figure 3-10 shows the log
output voltage as a function of pressure.
For added accuracy add .06 to V
NOTE
Leak Rate = 10
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.
