Section 6. Maintenance - Agilent Technologies VS Series Operation Manual

Section 6. Maintenance

A VS C-15 mass spectrometer leak detector requires periodic maintenance to ensure
continued reliable operation. After prolonged use, the leak detector accumulates
contaminants from even the cleanest of products tested that eventually impair operation. A
thorough disassembly and cleaning of the entire vacuum system, which includes the
spectrometer, restores normal operation. For heavy production use, more frequent
overhauls may be needed. In most cases, maintenance personnel do this work, but Agilent
can also do this work under the terms of a service contract.
This maintenance section covers daily and as-required maintenance. It does not cover
overhaul of the entire vacuum system. Refer to the VS C-15 Helium Mass Spectrometer Leak
Detectors Field Service Component Replacement Manual for annual and preventive
maintenance procedures.
If your leak detector requires service that is not covered in this section, contact Agilent
Customer Service. See the back cover of this manual for a listing of our sales and service
offices.

maintenance procedure that requires physically disconnecting
any part of the system.
The VS C-15 leak detector has a battery backed clock which
uses a primary (non-rechargeable) lithium coin battery from
Panasonic, P/N BR2477A/HB (3.0 V, 1 A) that is permanently
soldered onto a Motherboard PCB. Never replace this battery
with a rechargeable type. Use only the primary type of lithium
battery. Only a qualified technician should replace any battery.
The battery has a life of 7 to 10 years.
The VS C-15 leak detector uses fuses and circuit breakers that
are not operator replaceable. Only a qualified technician
should replace any fuse.
Information about the fuses and circuit breakers is given in
Table 6-3 on page 6-4.
