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,

MODEL 482B06 / F482B06 LINE POWERED SIGNAL CONDITIONER 1
1.0 Introduction and Specifications
Please turn to the end of this manual for a product
specification sheet and outline drawing.
1.1 Introduction: Safety Considerations
WARNING 1: The power supply/signal conditioner
should not be opened by anyone other than qualified
service personnel. This product is intended for use 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 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 with 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 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.
The Caution heading used in this manual explains
hazards that could damage the instrument.
1.2 Introduction
The Model 482B06 / F482B06 is a single-channel, line-
operated signal conditioner for use with ICP®sensor.
This unit provides a 24VDC, 4mA constant current
excitation to ICP® pressure, force or vibration sensors.
It also decouples the sensor’s DC bias voltage from the
AC measurement signal .
This unit also contains provisions for channel fault
monitoring, as well as a provision for externally varying
the constant current over a 2 to 20 mA range. This
model is factory set at 4 mA. ( Please refer the Model
482B06 / F482B06 specification sheet ).
2.0 Description
The Model 482B06 is powered by a 115V, 50-400Hz
AC line supply and the Model F482B06 by a 230V,50-
400Hz supply. The desired input power is selected by
using a switch located on the base. Other than that, there
is no difference in operation between the 482B06 and
the F482B06.
The rear panel contains one BNC jacks for sensor
INPUT and one BNC jack for signal OUTPUT
connection (refer Figure 3).
The AC measurement signal is decoupled from the
sensor DC bias by a coupling capacitor and brought to
the OUTPUT jack.
The bias or fault meter consists of a color-coded front
panel meter located on the front panel. The fault meter
reflect the measured sensor bias of that channel as being
in either the red, green or yellow. (refer Figure 1 and
section 3.0)
Please refer the sensor data sheet for specific sensor bias
voltage and additional specification.

3.0 Installation / Operation
See the included Outline Drawing for outline
dimensions, as well as jack and control locations. Plug
the supplied Model 017 AC line power cord into the IEC
320 AC power input connector located on the rear panel
of the Model 482B06/ F482B06.
Note: First make sure the selector switch located on
the base of the unit, is selected to the appropriate line
voltage of 115VAC for the 482B06 or 230VAC for
the F482B06.
Plug the three-wire line cord into a source of 115 VAC,
50-400 Hz power and turn on the power switch located
on the front panel of the Model 482B06. (Note : For
Model F482B06 use a 230VAC, 50-400 Hz source)
With nothing connected to the INPUT connector. The
front panel bias indicator/fault meter indicates full scale
(yellow), which corresponds to open circuit power
supply voltage. See Figure 1.
Meter Reading Yellow Green Red
Condition Open Ok Short
Figure 2: Fault Monitor Table
With an ICP®sensor (or in-line amplifier) connected to
the INPUT jack. The front monitor meter indicates
approximately midscale (green) if the sensor or amplifier
is functioning properly. (This reflect a typical bias of 8
to 12 volts. It does not read midscale if the transducer
bias is 3 to 5 volts and may be closer to red which is
expected for low bias sensors.)
If a cable is faulty (open), or the sensor's built-in
amplifier is open, the meter indicates a yellow (full
scale) reading. When a cable or sensor is shorted, the
meter indicates zero volts (red).
Connect the output jack to a read out instrument.
Immediately after connecting a readout instrument
(oscilloscope, meter, or recorder) to the OUTPUT jack,
the coupling capacitor begins charging through the input
resistance of the readout instrument. This charging
causes an apparent "drifting" of the output signal until
the capacitor is fully charged. The normal amount of
leakage through the coupling capacitor usually results in
a <30 mV maximum DC offset. After the system settles
out excite the sensor and proceed with making
measurements.
4.0 Coupling Time Constant, AC Coupled
The coupling time constant (TC) is the product of the
conditioner’s coupling capacitor (47 µF) and the input
resistance of the readout instrument, in parallel with the
274 kilohm shunt resistor. Typically, this is ten seconds,
assuming the input resistance of the readout
measurement is one megohm.
In most cases, it is desirable to keep the coupling TC
long, with respect to the sensor discharge TC, to
minimize the effect of the coupling TC on low frequency
response.

MODEL 482B06 / F482B06 LINE POWERED SIGNAL CONDITIONER 3
4.1 Driving Long Cables
When driving long cables, it may be necessary to
increase the constant-current drive to the sensor. The
Model 482B06 / F482B06 Power Unit is normally
supplied with the constant current output to the sensor
set at 4 mA nominal. This is adequate for most
laboratory and field applications. Special situations,
such as driving long cables (beyond 100 ft) with high
frequency or fast rise time pulses, may require
increasing the drive current to higher current levels (20
mA max).
When driving fast rise time pulses over long lines,
system performance may be optimized by "tuning" the
drive current to the line; i.e., by finding the best current
setting for the particular set of physical parameters
established by the sensor, line length, line termination,
pulse rise time, etc.
The optimum current setting is best determined by
experimentation with your particular test setup. A good
rule of thumb is to use the lowest current consistent with
satisfactory results to minimize sensor self-heating and
noise.
Another technique requires the use of the Model 073A
Impedance Matching Resistor connected immediately
after the sensor. This variable resistor is then used to
"tune" the current to the line. One of the best approaches
is to test the long line with a signal generator set at a
frequency of interest.
4.2 Setting the Constant Current
To set the constant current, locate the current adjust
potentiometer on the rear panel (as shown in Figure 3).
Connect a 0 to 30 mA DC ammeter (or multimeter) to
the INPUT jack. The constant current value is read
directly on the ammeter. Using a small regular
screwdriver, vary the setting of the current adjust pot to
set the current at a new level.
CAUTION: It may be possible to exceed 20 mA
slightly. Do not do so; as operation of an ICP®sensor or
amplifier above 20 mA may damage the equipment.
5.0 Warranty
PCB offers an unconditional guarantee for customer
satisfaction. PCB strives to provide superior, unmatched
customer service. Should you at any time find yourself
dissatisfied with any PCB product for any reason,
consult a PCB application engineer to discuss repair,
refund, or exchange procedures.
PCB instrumentation is warranted against defective
material and workmanship for one year unless otherwise
Figure 3: Constant Current Adjust

MODEL 482B06 / F482B06 LINE POWERED SIGNAL CONDITIONER 4
expressly specified. Damage to instruments caused by
incorrect power or misapplication is not covered by
warranty. If there are any questions regarding power,
intended application, or general usage, please contact a
PCB application engineer (or your local sales contact).
6.0 Maintenance and Repair
Because of the sophisticated nature of PCB
instrumentation, field repair of the equipment is not
recommended. Most PCB sensors are of modular
construction and are factory repairable. A repair or
replacement quotation is available at no charge. Before
returning equipment for repair, it is strongly suggested
that the user confer with a factory application engineer
(or local sales contact) concerning the difficulty and to
ascertain if an on-site procedure rectifies the problem.
If repair is indicated, contact PCB to request a Return
Materials Authorization (RMA) number from the
factory. An advanced authorization to proceed with the
repair, permitting charges of up to 50% of a new item,
greatly expedites repair.
For the most efficient service, please provide a detailed,
written description of the malfunction encountered with
the returned equipment, together with your specific
application and setup procedures. Customers outside the
U.S. should consult their local sales contact for
information on returning equipment. For exceptions,
