High Pressure Test Set-Up Procedure
The High Pressure Test mode locks the system into contraflow, offering maximum
protection to the spectrometer. This is useful in sniffing applications or when
evacuating parts that can contaminate the system.
To configure the High Pressure Test (optional):
1
If sniffing, vent the leak detector and attach a Agilent Power Probe
(Part Number K9565306) to the test port.
2
Monitor the test port pressure reading on the display and adjust the power
probe flow valve for a test port pressure of 0.5 to 1 Torr (2 Torr maximum). This
pressure setting allows for very rapid system response.
3
High Pressure Test mode sensitivity is 10
pressures between 1 and 2 Torr using the power probe.
When High Pressure Test is activated, range stop defaults to 10
High Pressure Test mode sensitivity is 10
pressures between 500mTorr and 2 Torr using the power probe. When High
Pressure Test is activated, range stop defaults to 10
between 10
4
Select High Pressure Test to enable the High Pressure Test mode.
5
When High Pressure Test is selected, Range Stop defaults to 10
High Pressure Test sensitivity mode range is 10
6
Wait for the leak detector to enter Vent mode.
7
Turn the High Pressure Test feature on to start the test cycle. This
automatically locks the leak detector into Contra-Flow™ Leak mode, and auto-
ranges through all decades down to the most sensitive Contra-Flow range.
8
Wait for the leak detector to be in Test mode.
9
Turn the High Pressure Test feature on to perform the same function, with the
exception of performing the test cycle start sequence.

This appears on the Home screen after a successful
startup. This timer is necessary for the spectrometer
stabilization and degassing. The factory default is 5
minutes. It is highly recommended for those
customers who infrequently use the leak detector or
expose the leak detector to aggressive applications to
select the 9 or 15 minute selection. For example: Select
9 minutes for a leak detector that is used once a week
or select fifteen minutes for a leak detector that is used
once a month or less.
