Total Customer Satisfaction –PCB
Piezotronics guarantees Total Customer
Satisfaction. If, at any time, for any
reason, you are not completely satisfied
with any PCB product, PCB will repair,
replace, or exchange it at no charge.
You may also choose to have your
purchase price refunded in lieu of the
repair, replacement, or exchange of the
product.
Service –Due to the sophisticated
nature of the sensors and associated
instrumentation provided by PCB
Piezotronics, user servicing or repair is
not recommended and, if attempted,
may void the factory warranty. Routine
maintenance, such as the cleaning of
electrical connectors, housings, and
mounting surfaces with solutions and
techniques that will not harm the
physical material of construction, is
acceptable. Caution should be observed
to insure that liquids are not permitted to
migrate into devices that are not
hermetically sealed. Such devices
should only be wiped with a dampened
cloth and never submerged or have
liquids poured upon them.
Repair –In the event that equipment
becomes damaged or ceases to
operate, arrangements should be made
to return the equipment to PCB
Piezotronics for repair. User servicing or
repair is not recommended and, if
attempted, may void the factory
warranty.
Calibration –Routine calibration of
sensors and associated instrumentation
is recommended as this helps build
confidence in measurement accuracy
and acquired data. Equipment
calibration cycles are typically
established by the users own quality
regimen. When in doubt about a
calibration cycle, a good “rule of thumb”
is to recalibrate on an annual basis. It is
also good practice to recalibrate after
exposure to any severe temperature
extreme, shock, load, or other
environmental influence, or prior to any
critical test.
PCB Piezotronics maintains an ISO-
9001 certified metrology laboratory and
offers calibration services, which are
accredited by A2LA to ISO/IEC 17025,
with full traceability to SI through
N.I.S.T. In addition to the normally
supplied calibration, special testing is
also available, such as: sensitivity at
elevated or cryogenic temperatures,
phase response, extended high or low
frequency response, extended range,
leak testing, hydrostatic pressure
testing, and others. For information on
standard recalibration services or
special testing, contact your local PCB
Piezotronics distributor, sales
representative, or factory customer
service representative.
Returning Equipment –Following
these procedures will insure that your
returned materials are handled in the
most expedient manner. Before
Warranty, Service, Repair, and
Return Policies and Instructions

returning any equipment to PCB
Piezotronics, contact your local
distributor, sales representative, or
factory customer service representative
to obtain a Return Warranty, Service,
Repair, and Return Policies and
Instructions Materials Authorization
(RMA) Number. This RMA number
should be clearly marked on the outside
of all package(s) and on the packing
list(s) accompanying the shipment. A
detailed account of the nature of the
problem(s) being experienced with the
equipment should also be included
inside the package(s) containing any
returned materials.
A Purchase Order, included with the
returned materials, will expedite the
turn-around of serviced equipment. It is
recommended to include authorization
on the Purchase Order for PCB to
proceed with any repairs, as long as
they do not exceed 50% of the
replacement cost of the returned
item(s). PCB will provide a price
quotation or replacement
recommendation for any item whose
repair costs would exceed 50% of
replacement cost, or any item that is not
economically feasible to repair. For
routine calibration services, the
Purchase Order should include
authorization to proceed and return at
current pricing, which can be obtained
from a factory customer service
representative.
Warranty –All equipment and repair
services provided by PCB Piezotronics,
Inc. are covered by a limited warranty
against defective material and
workmanship for a period of one year
from date of original purchase. Contact
PCB for a complete statement of our
warranty. Expendable items, such as
batteries and mounting hardware, are
not covered by warranty. Mechanical
damage to equipment due to improper
use is not covered by warranty.
Electronic circuitry failure caused by the
introduction of unregulated or improper
excitation power or electrostatic
discharge is not covered by warranty.
Contact Information –International
customers should direct all inquiries to
their local distributor or sales office. A
complete list of distributors and offices
can be found at www.pcb.com.
Customers within the United States may
contact their local sales representative
or a factory customer service
representative. A complete list of sales
representatives can be found at
www.pcb.com. Toll-free telephone
numbers for a factory customer service
representative, in the division
responsible for this product, can be
found on the title page at the front of this
manual. Our ship to address and

2.) TO AVOID UNNECESSARY DAMAGE TO THE SENSOR AND/OR CABLE, USE THE SUPPLIED REMOVAL TOOL
(MODEL 039A35). A QUICK TWISTING MOTION WILL FREE THE SENSOR FROM THE TEST STRUCTURE.
FASTEN CABLE TO TEST STRUCTURE TYPICALLY WITHIN 3 - 4 [76 - 101] OF SENSOR. THEN FASTEN AGAIN
WITHIN 3 - 4 [76 - 101] OF PREVIOUS ATTACHMENT. BETWEEN THE TEST STRUCTURE AND A FIXED STRUCTURE,
ALLOW A SERVICE LOOP LARGE ENOUGH TO PREVENT PULLING OF THE CABLE WHEN SHAKING. MORE
ATTACHMENT POINTS WILL PROVIDE LESS NOISE IN RESULTING DATA. LOOSE CABLES OR PARTS ELSEWHERE
ON THE TEST STRUCTURE CAN ALSO GENERATE "NOISE" ON THE SIGNAL RECEIVED FROM THE MODEL 352A74.
