Repair and Maintenance
PCB guarantees Total Customer Satisfaction through its
“Lifetime Warranty Plus” on all Platinum Stock Products
sold by PCB and through its limited warranties on all other
PCB Stock, Standard and Special products. Due to the
sophisticated nature of our sensors and associated
instrumentation, field servicing and repair is not
recommended and, if attempted, will void the factory
warranty.
Beyond routine calibration and battery replacements
where applicable, our products require no user
maintenance. Clean electrical connectors, housings, and
mounting surfaces with solutions and techniques that will
not harm the material of construction. Observe caution
when using liquids near devices that are not hermetically
sealed. Such devices should only be wiped with a
dampened cloth—never saturated or submerged.
In the event that equipment becomes damaged or ceases
to operate, our Application Engineers are here to support
your troubleshooting efforts 24 hours a day, 7 days a
week. Call or email with model and serial number as well
as a brief description of the problem.
Calibration
Routine calibration of sensors and associated
instrumentation is necessary to maintain measurement
accuracy. We recommend calibrating on an annual basis,
after exposure to any extreme environmental influence,
or prior to any critical test.
PCB Piezotronics is an ISO-9001 certified company whose
calibration services are accredited by A2LA to ISO/IEC
17025, with full traceability to SI through N.I.S.T. In
addition to our standard calibration services, we also offer
specialized tests, including: sensitivity at elevated or
cryogenic temperatures, phase response, extended high
or low frequency response, extended range, leak testing,
hydrostatic pressure testing, and others. For more
information, contact your local PCB Piezotronics
distributor, sales representative, or factory customer
service representative.
Returning Equipment
If factory repair is required, our representatives will
provide you with a Return Material Authorization (RMA)
number, which we use to reference any information you
have already provided and expedite the repair process.
This number should be clearly marked on the outside of
all returned package(s) and on any packing list(s)
accompanying the shipment.

401B04 ICP
®
Sensor Simulator
1. INTRODUCTION AND DESCRIPTION
The Model 401B04 is a unity gain, non-inverting, impedance-converting voltage amplifier with the same
characteristics as the built-in ICP
®
amplifiers provided in most PCB pressure sensors, force sensors, and
accelerometers. This model consists of MOSFET circuitry packaged in a convenient Pomona box with BNC
connectors. When used in conjunction with a signal generator or oscillator, it can be used in place of an ICP
sensor to calibrate ICP
®
sensor signal conditioners, do system verifications and gain adjustments, or check
frequency response of systems with long input cables. (The Model 401B04 simulates the circuit of an ICP
®
sensor while the signal generator takes the place of the sensor’s crystals.)
2. INSTALLATION AND OPERATION
CAUTION: Connect the output only to an ICP
®
type, current-limited signal conditioner.
WARNING: Excessive current may damage this model. Measure the ICP
®
sensor signal conditioner
current prior to connecting the 401B04. The ICP
®
excitation current should be ≤20 mA.
2.1 CALIBRATION OF ICP
®
SENSOR SIGNAL CONDITIONERS
Refer to the acceptance test procedure for your particular PCB signal conditioner, dual mode charge
amplifier, or digital peak meter model. (Acceptance test procedures are available for most PCB electronic
products. Consult factory for details.)
Connect a signal generator or oscillator to the input jack of the 401B04, after observing the caution and
warning above. Connect the output jack of the 401B04 to the ICP
®
sensor signal conditioner being
tested. (Various cables and adaptors are available from PCB as needed.) Switch on the signal
conditioner and note the output bias voltage on the meter as you would for any ICP
®
sensor. The meter
should read mid scale, indicating that the 401B04 is operational. Follow the acceptance test procedure
for your particular PCB model. The exact gain factor (near unity) of the 401B04 is noted on the
calibration certificate supplied with the unit. The nominal value of Gain = 1.0 is on the housing of the unit.

2.2 MEASUREMENT SYSTEM CHECKOUT AND/OR GAIN ADJUST
The Model 401B04 is inserted in place of the ICP
®
sensor in your measurement system. Connect the
input of the 401B04 to a signal generator and the output to the ICP
®
sensor signal conditioner. Also
connect any additional amplifiers or recording devices that will be used in the test, as shown in the figure
above. After switching on all equipment and allowing sufficient warm-up time, apply a known signal
through the system with the signal generator and adjust gains, ranges, zeroes, etc., as needed.
2.3 CALIBRATION OF LONG LINES
Model 401B04 can be used, in conjunction with an oscillator or step function generator, to simulate an
ICP® sensor driving a long input cable between the sensor and the ICP sensor signal conditioner. Refer
to PCB “General Guide to ICP® Instrumentation” for more details on the procedure.
3. FREQUENCY RESPONSE CONSIDERATIONS
When used with a signal generator for system checkouts or testing of long lines, low frequency response of
the 401B04 is DC.
High frequency response of the Model 401B04, when driving short cables with small (~1V) signals, is 1
megahertz. Refer to PCB “General Guide to ICP® Instrumentation.” if long cables are to be driven. Also,
consult the factory if less than 2 mA constant current will be used to power the 401B04.
4. MEASUREMENT AND REPAIR
The miniature size precludes most maintenance. If used in a very humid or dirty environment, signal
degradation, usually in the form of reduced output or loss of low frequency response, may occur. If the
connectors become dirty, clean with Freon TF ®, Genesolv, or other suitable solvent that leaves no residue.

Optional versions have identical specifications and accessories as listed for the standard model except
where noted below. More than one option may be used.
NOTES:
[1]Above stated frequency, the amplifier becomes slew rate limited.
[2]Voltage < 20 VDC reduces input range to ±3V.
