Optional - Enter an Audio Set Point value.

oSplit 1-3
Extended Split Flow is used in applications where the External Standard Leak values
are greater than the upper leak rate limit of the leak detector (>9.9E-4 std. cc/sec
He) but can be measured due to a large split flow condition.
Example: 5E-1 std. cc/sec He standard leak measures 5E-5 std. cc/sec He on the
Agilent Helium Leak detector. The out of range Installed Leak Value can be entered
and Extended Split Flow can be activated.
The software limits split flow to no more than 1000 times (3 decades). If the split
NOTE
flow is turned ON and the leak rate entered is more than 1000 times higher than the
system leak rate, the system will not allow the split flow to turn ON and <> appears.
At the main screen, the system blinks the split flow symbol when split flow
is ON
When split flow is turned ON, it displays the corrected leak rate but it knows the real
leak rate value. When ZERO is pressed with when split flow ON, the system zeroes
out background up to a limit equal to the maximum split flow value.
