Agilent Field Instruction Sheet
Calibrated Leak Replacement for VS C15, VS, and (G8610, G8611, or G8612) Series Leak Detectors
Preface
This instruction sheet gives the procedure for replacing the calibrated leak for both the VS C15 (“Section One: VS C15
Calibrated Leak Replacement” on page 3), VS Series leak detectors (“Section Two: Calibrated Leak Replacement for
VS Series Leak Detectors” on page 7), and (G8610, G8611, or G8612) series leak detectors ("Section Three: Calibrated
Leak Replacement for G8610, G8611, or G8612"). This manual is shipped with material VSFLDCL for calibrated leak
replacement.
Documentation Standards
This manual uses the following documentation standards:
NOTE Notes contain important information.
CAUTION
Cautions appear before instructions, which if not followed, could cause damage
to the equipment or data loss.
WARNING
Warnings appear for a particular procedure or practice which, if not
followed correctly, could lead to serious injury or death.
Hazard and Safety Information
Operators and service personnel must be aware of all hazards associated with this equipment. They must know how
to recognize hazardous and potentially hazardous conditions, and know how to avoid them. The consequences of
unskilled, improper, or careless operation of the equipment can be serious. Every operator or service person must
read and thoroughly understand operation/maintenance manuals and any additional information provided by Agilent.
All warning and cautions must be read carefully and strictly observed. Consult local, state, and national agencies
regarding specific requirements and regulations. Address any safety, operation, and/or maintenance questions to
your nearest Agilent office.
Solvents
WARNING
The mechanical components of leak detectors may be cleaned with one of the
recommended solvents. When heated, sprayed, or exposed to high-temperature
equipment, these solvents become flammable and explosive, causing serious
injury or death. Do not use these solvents near a high-temperature source.
Ventilate the working area with a blower and work in a large, well-ventilated room.

Solvents are irritants, narcotics, depressants and/or carcinogens. Their inhalation
and/or ingestion may produce serious side effects. Prolonged or continued
contact with the skin results in absorption through the skin and moderate toxicity.
Always ensure that cleaning operations are carried out in large, well-ventilated
rooms, and wear eye shields, gloves, and protective clothing.
Vacuum Equipment and Cleanliness
Cleanliness is vital when servicing the leak detector or any vacuum equipment. There are some techniques that
are more important in leak detector servicing than in general vacuum work:
O-ring Care
When removing, checking or replacing O-rings, keep in mind the following:
NOTE Agilent recommends replacing all O-rings during routine maintenance or during
any maintenance procedure requiring that O-rings be removed.
CAUTION Remove O-rings carefully with your fingers. Do not use metal tools for this task; this
prevents scratching of any sealing surfaces.
•Wipe all O-rings clean with a lint-free cloth before installation to ensure that no
foreign matter is present to impair the seal.
•Do not use grease or any other substance on O-rings that will come in contact
with the vacuum surfaces.
•Do not use alcohol, methanol or other solvents on O-rings. Doing so causes
deterioration and reduces their ability to hold a vacuum.
•Agilent does not recommend the use of vacuum grease. If applicable, apply a
small amount of Apiezon®L grease and wipe the O-rings shiny dry.

Section One: VS C15 Calibrated Leak Replacement
Equipment Required
•M4 Allen Wrench
•Flat Head Screwdriver
Installation Procedure
WARNING Disconnect power from the unit before performing any maintenance procedure that
requires physically disconnecting any part of the system.
1. Disconnect the power to back of the unit and unplug.
2. Wait 30 seconds for the high voltage to dissipate.
3. Using an M4 Allen wrench, remove the two screws on the unit’s top and open the unit (Figure 1: Unit Top Screws).

4. Loosen and remove the clamp (Figure 2: Remove Clamp).
Figure 2: Remove Clamp
5. Disconnect the cable from the calibrated leak board (Figure 3: Cable to Calibrated Leak Connection).

6. Remove the assembly and use a flat head screw driver to remove the two screws holding the calibrated leak
(Figure 4: Calibrated Leak Screws).
Figure 4: Calibrated Leak Screws
7. Discard the calibrated leak and the O-ring.
8. Inspect the replacement calibrated leak and O-ring for damage or particle contamination and remove any
particle contamination.
9. Install the O-ring in the groove and then assemble the replacement calibrated leak to the valve block using a
slotted screwdriver.
10.Connect the calibrated leak temperature cable end labeled P1A to the leak assembly board connector J1A
(Figure 5: Leak Assembly Board Connection).

11.Reattach the leak assembly to the flange with the clamp.
12.Close the cover and secure using the existing hardware.
13.Power up the VS C15 component leak detector.
14.Set up the Internal Calibrated Leak by either:
•Setting up the Internal Calibrated Leak Option via the front panel display by:
a. Select Advanced Parameters > Internal Type and select STD LEAK.
b. Select Maintenance > Internal Calibrated Leak and input the calibration data from the Calibration Certificate
for the internal calibrated leak including:
• Internal Leak Value
• Temperature
• Temperature coefficient factor
• Cal Leak - Date of Expiration
c. Validate the setup using the Calibration Set Up menu: the temperature compensated leak value, internal
cali-brated leak temperature and date of expiration.
—or —
•Setting up the Internal Calibrated Leak Option via the RS232 serial communications port (see the operation
manual for communicating via the RS232 serial port) by:
a. Enter the following commands:
•1 INIT-INTERANL-TYPE
•X.XE-0X INIT-STDLEAK (Enter the leak rate value from the calibration certificate ex. 1.8E-07 INIT-STDLEAK).
•XX.X INIT-LEAKTEMP (Enter the temperature from the calibration certificate ex. 23.5 INIT-LEAKTEMP).
•-/+XX INIT-TEMPFACTOR (Enter the temperature coefficient from the calibration certificate ex. -7 INIT-
TEMPFACTOR).
•mm dd yyyy INIT-LKEXPIRE (Enter the date of expiration from the calibration certificate ex. 12 22 2008 INIT-
LKEXPIRE).
b. Validating that the correct internal leak data was inputted (data from the Calibration Certificate) by:
• ?STDLEAK (reports back the value of the internal calibrated leak).
• ?LEAKTEMP (reports back the temperature of the calibrated leak from the factory calibration).
• ?TEMPFACTOR (reports back the temperature coefficient).
• ?LKEXPIRE (reports back the date of expiration).
Perform an internal calibration (via the I/O, Front Panel Display or RS232) to validate a successful installation of
the internal calibrated leak.
