2 Fluke Calibration 525B Temperature/Pressure Calibrator
A good fit for ATE test
applications
With precise calibration-grade
instrument control enabled
via an IEEE bus, the 525B is a
hardworking addition to auto-
mated test systems in quality and
manufacturing test applications
requiring capabilities such as
voltage and current sourcing,
sensor simulation, and tempera-
ture monitoring and validation.
Powerful functionality
that is easy to use
From start to finish, the 525B
is designed for ease of opera-
tion. The intuitive front panel
design features large keypads
and display that help reduce
training time and make the 525B
comfortable to use even for long
periods of time. Plus, you can
store frequently used constants
for a variety of probes in memory
for faster setup on the job.
MET/CAL® Plus automates
525B calibration and docu-
mentation management
You can use the 525B with
MET/CAL Plus calibration software
(V.6.11 or later) to meet the strin-
gent documentation and reporting
requirements imposed by quality
standards such as ISO 9000.
MET/CAL Plus is a powerful
software environment for creating,
editing, testing, and documenting
calibration procedures, and for
performing automated calibrations.
At the core of MET/CAL Plus
is MET/TRACK® software, a
database management system
for test and measurement assets
created specifically to manage
equipment. It enables you to
track the information you need to
maintain quality calibrations. And
it supports the traceability and
record-keeping requirements of
modern quality and accreditation
standards.
MET/TRACK provides you with a
variety of standard report formats
prepared with Crystal Reports™
Professional, which is included
with MET/CAL Plus. These report
formats cover a wide range of
information to help you meet
many of your documentation
requirements, including those
for ISO 9000 and similar quality
standards. They report on forward
and reverse traceability, allowing
you to easily document traceabil-
ity from any asset to the equip-
ment calibrated. It even includes
measurement uncertainty report-
ing to meet the requirements of
ISO/IEC 17025.
Pressure modules
An optional set of external pres-
sure modules provides pressure
measurement capability. The
525B can accept either the Fluke
700 Series or the 525A-P pres-
sure modules. Both module types
plug directly into the calibrator’s
front panel Lemo connector; the
525B firmware auto-detects the
type and value of the attached
module.
World-class temperature
and pressure calibration
solutions
In addition to the 525B Tempera-
ture/Pressure Calibrator, Fluke
Calibration offers a broad range
of solutions in temperature and
humidity calibration as well as
pressure and flow calibration.
Fluke Calibration makes every-
thing you need for calibrating
temperature sensors including
SPRTs, PRTs, thermistors, and
thermocouples. The constant
temperature baths and dry-block
calibrators offer unmatched stabil-
ity, and the primary temperature
standards are used in national
metrology institutes around the
world. For precision thermometry,
Fluke Calibration thermometer
readouts and probes are excep-
tionally accurate and easy to use,
and the 1620A “DewK” tempera-
ture and humidity data logger
handles your environmental
monitoring needs.
Fluke Calibration also offers a
range of high-end products focus-
ing on pressure and flow calibra-
tors and standards. More than 30
national measurement institutes
rely on Fluke Calibration pressure
standards to establish their pres-
sure references. Fluke Calibration
pressure standards, transfer stan-
dards, pressure controller/calibra-
tors and monitors are recognized
for their advanced features and
the realistic specifications that are
the hallmark of a true metrology
company.
Calibration service, repair,
and support
Fluke Calibration provides exten-
sive calibration support and
service to maximize the value of
your calibration investment. Our
worldwide network of Calibration
Centers has traceability to national
standards. Service and support
are just a telephone call or fax
away. We offer fast, quality repair
and calibration services includ-
ing a module exchange program,
comprehensive training, and full
support in setting up your lab.
