Graph Screen Scaling
The graph is painted on the screen in two scales. Fast Fill, Fill, and Settle are scaled by the test
pressure and plus/minus tolerances. The Test step is scaled to the test limits.
For example, if the test pressure were 10.0psi and the ± tolerances were 0.5 psi, the test
pressure would be center in the horizontal, the top of the screen would be 10.5psi and the bottom of
the screen would be 9.5psi.
If the test limits were 0.050psi the top horizontal would be zero decay and the bottom of the
screen would be 0.050psi decay.
Timer Bar
During the
Fill
and
Settle
steps the
center of the graph equals the set
test pressure value. The top of the
graph is
+
tolerance and the bottom
of the graph is the
–
tolerance.
During the
Test
step the top of the
bar is zero decay and the bottom of
the bar is the reject level. The white
arrow shows the live value.
The
‘
BAR
’
run screen shows the relevant
test values at a graphical glance.
The timer bar is a graphical representation
of the step time. Each step will reset the
bar to full height to correspond the step
time.
