Split Flow Setup - Agilent Technologies G8610A Operation Manual

Agilent Technologies Helium Leak Detector
7. Enter the value of the installed external calibrated leak.
8. Optional - Enter a Set Point 1 leak rate value.
9. Optional - Enter an Audio Set Point value.
10. Press Continue.
"Files - operator can store up to three setup configurations:
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.
NOTE
Figure 5-13 Split Flow Setup
The software limits split flow to no more than 1000 times (3
decades). If the split 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.
