The audio signal increases from a low to high frequency as the leak
rate increases within each decade.
The pitch cycles low to high as it passes through each decade. The
audio response corresponds directly to the size of the leak.
To turn the sound on/off, press the speaker button. The volume
level is restored to the level it was at prior to being turned off.
Toggles the graphing time between 120 and 720 seconds. The
timer automatically defaults to 120 seconds on leak detector start
up. Press the toggle button while graphing to clear the current
graph. The data rate for the timers are:
120 seconds - two measurements/second
720 seconds - one measurement/three seconds.
Clears the plotted graph. The graph automatically clears when the
leak detector is in roughing mode or at the start of a new test.
Zeroes out the displayed helium leak. The leak rate must be less
than 4.0E-7, while in Test, to allow a cross over to Fine Test.
This button causes the leak detector to reset the leak rate display,
while the graph tracks the effect of the Zero command.
Tapping the graph
function symbol
toggles between the
Home and graphing
display.
