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

SENSORS AND INSTRUMENTATION FOR MACHINE CONDITION MONITORING
Introduction
The 682 Series is a 4-20mA Din Rail Signal Conditioner designed to interface with IMI Sensor’s ICP®
Accelerometer. Acceleration, Velocity, or Displacement can be converted to a 4-20mA signal by simple DIP
Switch selection internal to the Din Rail enclosure. An additional standard feature of the 682 Series is the ability to
convert the temperature output from an accelerometer (when equipped) to 4-20mA. Signal Filtering can be easily
configured in the field by installing factory calibrated Filter Modules into sockets located inside the enclosure.

Filter Module Location
The Filter Modules are utilized to set the cutoff frequency of the internal band pass filter circuit. The 682 Series
comes standard with Modules preinstalled. If a different cutoff frequency is desired, the preinstalled module can
be removed by simply pulling it out of the MOD socket, and replacing it with a different module. The module is
labeled with the type of filter, Low Pass or High Pass, and the cutoff frequency. Module location is as follows:
MOD1: Low Pass (LP) Filter Module Location
MOD2: High Pass (HP) Filter Module Location
Warning: Do not make any adjustments to the internal potentiometers. These potentiometers are used for
factory calibration and adjusting them will require return of the 682 Series unit to the factory for recalibration.

Warning 1 –ESD sensitivity
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 –ESD sensitivity
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 –ESD sensitivity
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, and/or
Contact with a non-grounded person.
The PCB solution for product safety:
Connect the cables only with the AC power off.
Temporarily “short” the end of the cable before attaching it to any signal input or output.
Caution 2 –ESD sensitivity

PAGE 13
SENSORS AND INSTRUMENTATION FOR MACHINE CONDITION MONITORING
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.
