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

Introduction
Model 480C02 & model 480E09 are rugged, portable, power sources for ICP® sensors. These models are nearly
identical except model 480C02 is unity gain 1:1 only with no adjustment, while model 480E09 has the additional
feature of 3-position gain adjustment (1/10/100). They are powered internally by three replaceable batteries and
provide constant current excitation to the charge amplifier within ICP® sensors (or to in-line and adaptor style
amplifiers) and decouples the sensor output signal from the power. Signal output is a high quality, voltage output
compatible with standard readout, recording or acquisition instruments.

Figure 2: Model 480E09 Signal Conditioner
Description
Models 480C02 / 480E09 contain three, PP3 size, 9 volt batteries connected in series to provide DC power to
internal electronics which provide regulation for approximately 2.6 mA of constant current power. Connections
include two BNC jacks, one for Sensor (ICP®power/input) and one for Scope (output to scope, data recorder, or
DAQ). The front panel meter indicates the voltage output when connected to a sensor and is color coded for
various fault conditions, shown in Figure 1 & 2. Optional connections include sockets for EXT PWR and BATT
CHG. A central, three-position rocker switch allows off, on and momentary battery test functionality.
Model 480E09 has the additional 3-position gain adjustment that multiplies the signal output through the SCOPE
connection. It has 2 additional settings beyond the 480C02, 10x and 100x, shown in Figure 2.

Operation
Internal electronics include a capacitor and resistor that decouples the sensor output signal from the DC power.
With no sensor connected, move power switch to “ON” position. The front panel voltmeter measures the battery
voltage with full scale set at 27 volts (+27 volts for new batteries), see Figure 1. When an ICP® sensor is
connector to the input “XDCR” jack, the meter will indicate approximately mid-scale (+11 volts nominal) if the
sensor’s internal amplifier and cables are functioning properly without damage. Some sensors use a 5 volt
excitation and in this case the meter will read at the lower edge of the green region.

Mode
If the sensor amplifier and/or cable are damaged to short open, the meter will indicate in the full scale (yellow)
area. Should the sensor amplifier and/or cable be damaged to short closed, the meter will indicate zero volts (red
area). Immediately after connecting readout instrument, (oscilloscope, meter, recorder, etc.) to the output jack,
the 47 F coupling capacitor will begin charging through the internal resistor and input resistance of the readout
instrument. This charging will cause an apparent “drifting” of the output signal until the capacitor is fully charged.
Such drifting is considered normal operation.
Coupling Time Constant (TC), AC Coupled
The coupling discharge time constant (DTC) is the
product of the capacitor (47 F) and the parallel internal
resistor and the input resistance of the readout
instrument (See Figure 4, Equation 1).
Equation 1:
TC (sec) = Cc(microfarads) x Rin (ohms)
The small amount of leakage through the 47F coupling capacitor will typically result in a +30 mV maximum offset
with a 1.0 megaohms readout load. Normally, it is desirable to keep the coupling discharge time constant (DTC)
long with respect to the sensor discharge time constant to minimize the effect of the coupling distance time
constant on low frequency response. Typical coupling discharge time constants for various values of readout
input resistance are shown in Table 1.

DC Coupling for Low-Frequency Response
With the 480C02 / 480E09 connected as shown in Figure 5, the low frequency response of the coupling
circuit is determined by the relationship in Equation 2. This requires use of a BNC Tee. Figure 6 below
provides a comparison of AC vs DC coupling the same signal.

Performance Limits
Output Voltage Limits
Certain ICP sensors are capable of 10-volt output voltage swing. Models 480C02 / 480E09 with 27 volt
supply will allow the positive-going side of the signal to go to +14 volts. The negative signal side is
capable of -8 volts assuming a 10 volt turn-on for the sensor. This must be taken into consideration or
resulting outputs may show signs of clipping.
Constant Current Limits
When using battery powered signal conditioners, battery life can be a concern. The current output of
model 480C02 / 480E09 is fixed at approximately 2.6 mA. This current will adequately handle high-
frequency signals in cables up to approximately 100 feet (31 meters) in length. Longer cables can be
driven but it sacrifices some high-frequency response. PCB line powered signal conditioners (482 Series
/ 483 Series) should be considered for cable lengths beyond 100 feet (31 meters) as they provide up to
20 mA of drive current.
Battery Considerations
Battery Test
Models 480C02 / 480E09 incorporate a momentary battery test position in the 3 position switch. When
the rocker switch is depressed to the right, the meter switched from the “XDCR” jack to the battery power
high-side. Normal circuit operation is not affected by this change and releasing the rocker returns the
meter to the transducer fault monitor function. It is recommended to confirm the status of batteries before
initiating a test. Replace batteries any time the pointer does not reach the BATT OK position or further
when the BATT Test switch is depressed. A slightly low reading will limit the usable output of most
sensors but will not cause damage to the model 480C02 or connected sensors.

MANUAL NUMBER: 19175
MANUAL REVISION: A
Battery Life & Replacement
Typical battery life is 100 hours at gain of 1 or 40 hours at gain of 10 or 100 when using high quality
alkaline batteries, assuming the unit is turned off when not in use. When a BATT Test fail occurs, find
and carefully remove the Philips head screw on the back of model 480C02. The housing will easily
separate from the working portion of the unit and expose the batteries. Gently remove each of the battery
connectors to avoid damage and remove the batteries. Re-install new PP3, 9-volt batteries in same
locations, making sure all are of the same type and same manufacturer. Replace housing and hand-
tighten screw on back of unit. It is not recommended to mix type or manufacturer of batteries or damage
can occur as batteries rupture or leak. It is recommended to remove batteries from units not in frequent
use, to avoid any damage from long-term battery corrosion.
Optional Power Connections
Rechargeable Battery Use & Charging
WARNING, models 480C02 / 480E09 do not ship with rechargeable batteries and PCB external battery
chargers are suitable for use with Nickel-Cadmium (Ni-Cad) rechargeable batteries only. It should not
be used with alkaline or other non-rechargeable batteries.
Use of battery chargers, model 488A02 (110 VAC) or model F488A02
(220 VAC) should only be attempted after installation of suitable
batteries. Plug 488A02 charging connector into front panel jack and
with unit off, recharge for 14 hours. Charger supplies 10 mA constant
current to the rechargeable batteries in the unit. Batteries should not
be charged in areas near combustible materials or left unattended.
Disconnect all power if any evidence of overheating occurs.
External Power Connection
The external power connector (which mates with a #750 Switchcraft telephone plug) is intended for use
when longer battery life is desired. Insertion of the plug into the jack isolates the battery power
connection, powering the unit from only the secondary power source. A variety of battery packs were
previously available for use with this connection, one being model 073A05. They are still viable for use,
but are no longer in production from PCB.
