The information contained in this document supersedes all similar information that
may be found elsewhere in this manual.
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 ensure 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 ensure that your
returned materials are handled in the
most expedient manner. Before
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
Service, Repair, and Return
Policies and Instructions

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.
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

MULTICHANNEL SIGNAL CONDITIONER MODEL 482C GENERAL OPERATION MANUAL
1
1-1. Introduction
Model 482C05 is a basic ICP signal conditioner that provides an adjustable current source to drive ICP sensors.
Additionally it has open, short and overload input fault condition indicators.
Model 482C15 is an ICP®signal conditioner that has all the features of the 482C05 plus jumper selectable (x1, x10, and
x100) gain options and an overload range selection. An easy to open cover, allows access to the jumper selections.
The following sections describe these devices in more detail.
1-2. Safety Considerations
WARNING SYMBOLS AND TERMS
The following symbols and terms may be found on the equipment described in this manual.
This symbol on the unit indicates that the user should refer to the operating instructions located in the manual.
This symbol on the unit indicates that high voltage may be present. Use standard safety precautions to avoid
personal contact with this voltage.
This symbol indicates that the test fixture, Model 482C15, must be connected to earth ground via the power cord.
The WARNING heading used in this manual explains dangers that might result in personal injury or death. Always
read the associated information very carefully before performing the indicated procedure.
The CAUTION heading used in this manual explains hazards that could damage the instrument.
WARNING 1: The power supply/signal conditioner should not be opened by anyone other than qualified service
personnel. This product is intended for service by qualified personnel who recognize shock hazards and are familiar
with the safety precautions required to avoid injury.
WARNING 2: This equipment is designed with user safety in mind; however, the protection provided by the equipment
may be impaired if the equipment is used in a manner not specified by PCB Piezotronics, Inc.
CAUTION 1: Cables can kill your equipment. High voltage ElectroStatic Discharge (ESD) can damage electrical
devices. Similar to a capacitor, a cable can hold a charge caused by triboelectric transfer, such as that which occurs in
the following:
Laying on and moving across a rug.
Any movement through air.
The action of rolling out a cable.
Contact to a non-grounded person
The solution for product safety: 1) Connect the cables only with the AC power off. 2) Temporarily “short” the end of
the cable before attaching it to any signal input or output.
CAUTION 2: ESD considerations should be made prior to performing any internal adjustments on the equipment.
Any piece of electronic equipment is vulnerable to ESD when opened for adjustments. Internal adjustments should

MULTICHANNEL SIGNAL CONDITIONER MODEL 482C GENERAL OPERATION MANUAL
2
therefore be done ONLY at an ESD-safe work area. Many products have ESD protection, but the level of protection may
be exceeded by extremely high voltage that is typically present in normal situations.
1-3. Equipment Rating
For complete specifications, please refer to the enclosed specification sheet. This equipment operates optimally at +32
to +120°F (0 to +50°C), in an environment having < 85% relative humidity. Its line power frequency range is
47 - 63 Hz.
The 482C05 and 482C15 devices require 32 - 38 VDC with approximately 200 mA to operate. In turn, they supply
26 VDC @ 2 - 20 mA excitation voltage to connected ICPsensors or in-line charge converters. The units get power
via PCB model 488B04 AC power adaptor (supplied with model), PCB model 488A11 car adapter or a 36 VDC battery
pack. All of these plug into a 5-socket DIN female connector on the rear panel. External power pin out information is
provided in section 1-8.3.
1-4. Model 482C15 System Description
Model 482C15 is a four channel signal conditioning unit designed to interface measurement signals to readout or
recording devices.
The following are features that come standard on 482C15 units:
Input fault and overload LED’s with jumper selectable overload level of +/-5V or +/-10V
Variable ICP®source current, 0 to 20 mA
Jumper selectable Voltage input mode
Jumper selectable gain of x1, x10, x100 (482C15 Only)
Lighted power indicator on the front panel

1-4.3. Fault Indications
The three red LED’s on the front panel are all indicators of some type of problem. The normal operation state is when
all fault lights are off. The “OPEN” light indicates that the bias voltage is over that of most sensors and is close to an
open circuit voltage of 26 VDC. The photo on the cover is shown with the unit on, and no sensors attached, so the
“OPEN” LED is on. The “SHORT” light indicates a very low bias voltage close to 0 VDC. The “OVERLOAD” light
indicates a signal level of +/- 10 V peak has been detected and the signal may be in danger of clipping. These fault
lights are active for all channels at the same time.
1-4.4. Gain selection / Jumper definition
The 482C15 has internal jumpers that are accessed by opening the top cover. On each side of the unit are small slots,
which can be accessed with a medium size flat screwdriver. Press the blade into the slot gently, and the locking device
will be released, allowing the cover to be opened. The various jumpers are all labeled on the PC board. Each channel
can be set to your selected gain and other options. The selection of all these features with jumpers allows the 482C15 to
have the functionality of many other higher priced units at an economical cost. See the table that explains the function
and number of each jumper. “X” represents channel number.

1-5. Model 482C05 System Description
Model 482C05 is a basic four channel signal conditioning unit designed to interface measurement signals to readout or
recording devices.
The following are features that come standard on every 482C05:
Unity gain
Input fault and overload LED’s
Variable ICPsource current, 0 to 20 mA
Lighted power indicator on the front panel
Rear panel BNC input/output connectors
1-5.1. Model 482C05 ICP®Input/Output Mode
Model 482C05 contains a regulated 26 VDC power supply that provides constant current for up to 4 individual
channels. Both the output and input connections utilize BNC connectors and are brought out through the rear panel. The
unit is AC coupled only. The 482C series offers optional DC Coupling. Consult factory.
1-5.2. Adjusting the Current Source
The current adjustment is located on the rear of the unit. Use a standard small flat screwdriver to adjust the “I ADJ”
potentiometer located on the rear panel between channel 2 and 3 inputs/outputs (see section 1-4.2 for photo of current
adjust location). Turning the adjustment slot clockwise will increase the current, while counterclockwise will decrease
the current. Do this adjustment only while a DC mA meter or DMM set to mA is connected to any “ICP” BNC. One
adjustment controls all channels. The unit is factory set to 4 mA and can be adjusted between 0 - 20 mA.
1-5.3. Fault Indications
The three red LED’s on the front panel are all indicators of some type of problem. The normal operation state is when
all fault lights are off. The “OPEN” light indicates that the bias voltage is over that of most sensors and is close to an
open circuit voltage of 26 VDC. The photo on the cover is shown with the unit on, and no sensors attached, so the
“OPEN” LED is on. The “SHORT” light indicates a very low bias voltage close to 0 VDC. The “OVERLOAD” light
indicates a signal level of +/- 10 V peak has been detected and the signal may be in danger of clipping. These fault
lights are active for all channels at the same time.
1-6. Installation
Both 482C15 and 482C05 come packaged in a standard box and require very little in terms of installation. The box
should be located in such a way as to allow convenient access to the power outlet for disconnect purposes. Since these
units have low power consumption, they can be located in confined environments.
1-7. Grounding Techniques
Integrating either of these models into an application that links the outputs to other test equipment powered by line
voltages may lead to errors or loss of signal-to-noise ratio due to ground loops. The evidence of ground loops is easily
seen whenever the fundamental frequency (50 or 60 Hz) or a multiple of the fundamental frequency is present in the
system when the sensors are “at rest.” In order to maintain the operating specification of noise and reduce the effects of
line interference, proper grounding techniques should be used. The following procedure may be helpful:

MULTICHANNEL SIGNAL CONDITIONER MODEL 482C GENERAL OPERATION MANUAL
5
1. Make sure the signal ground lines of all equipment are tied together. The signal grounds of the channels are typically
tied together via the case of the input and output BNC connectors. The individual channels of the Model 482C15 and
482C05 have their signal ground line tied together internally at the power supply.
2. Insure that the sensor does not pick up line noise from the body under test. The case of the sensor should be isolated
from the body under (ground) using an isolation pad. The isolation pad breaks the loop formed by the signal path of the
sensor to the unit and the return (ground) from the unit back to the sensor.
3. Make sure that all equipment signal grounds of the test system are tied to the Earth ground at a single point and the
connections linking the equipment ground are made using a wire that can provide a very low impedance connection.
1-8. Unit Power
1-8.1. Power: Standard AC Line adapter Model 488B04 (supplied with unit)
Plug the adapter into any 100 - 240 VAC 47 - 63 Hz power source, attach the supplied ferrite clamp on the AC cord to
ensure CE conformance, and press the “ON/OFF” button.
1-8.2. Power: Optional auto adapter Model 488A11
Plug the adapter into a 12 VDC power source, or automobile cigar lighter socket and press the “ON/OFF” button.
1-8.3. Power: Using other 36 VDC power sources, or batteries (not supplied with unit)
When using any 36 VDC power source for power, make sure to observe the correct pin out, as indicated on the rear
panel of the unit. Both models use a standard 5-socket DIN female connector. Pin information is provided below.
Pins 3 and 5 are (+)
Pins 1, 2 and 4 are (-)
Outside shell is earth/chassis ground
CAUTION 3: Refer to the rear panel for proper input voltage. Only PCB supplied power sources will
ensure noise specifications and CE ratings.
