Calibrate a wide range of pressure
gauges and sensors with this reliable,
easy-to-maintain instrument
The Fluke Calibration 6270A
Pressure Controller/Calibrator is a
robust, reliable solution that lets
you dramatically simplify the task
of pneumatic pressure calibration.
Thanks to its modular design, it
is so flexible that it can be configured to meet a wide variety of
needs and budgets, and expanded
to cover a very broad workload,
at purchase or later as your needs
change and grow.
The 6270A is ideal for pressure
sensor manufacturers who want
to avoid downtime on the production line and need a pressure
source that performs both quickly
and accurately. Its modular design
makes it easy to maintain; its high
speed control and accuracy over a
wide range give them the throughput they require.
Managers and technicians in
calibration laboratories and instrument shops appreciate the 6270A
calibrator’s control precision and
accuracy over a wide pressure
range, which enables them to
calibrate a wide range of devices
with a single calibrator. They also
like the contamination prevention
option that provides an important
safeguard against that pervasive

Calibrate a wide
accurately, dependably
The 6270A features pressure
ranges from low differential pressure to 20 MPa (3000 psi), which
covers the requirements of most
gauges and sensors. Two levels
of accuracy, 0.02 % FS or 0.01 %
reading, let you balance your
need for accuracy with the limits
of your budget.
Thanks to its modular design,
the 6270A is flexible enough
that you can install modules
with different accuracy classes
within the same chassis. You can
buy the highest level of accuracy for the pressure ranges that
require it and a lower,
more economical level
of accuracy for everyMix and match
thing else.

The 6270A’s accuracy

and supported by a
Technical Note that
details its measurement uncertainty, so
you know exactly what you are
getting. The Technical Note is
available for download on the
flukecal.com website. As with all
Fluke Calibration instruments,
these specifications are conservative, complete, and dependable.
Cutting edge technology
and performance
The PM600 Pressure Measurement
Modules use the Fluke Calibration
Quartz Reference Pressure
Transducer (Q-RPT) technology to provide 0.01 % reading
measurement uncertainty from
30 % to 100 % of the modules
span. The modules are available
in 14 different ranges including
modules that are inherently absolute mode and gauge mode. The
absolute mode modules include an
onboard barometer. The barometer
provides dynamic compensation
of changes in atmospheric pressure, allowing for the modules
usage in both absolute and gauge
mode. The wide percent of reading capability combined with its
ability to measure both gauge and
absolute gives the PM600 Pressure
Measurement Module the ability to
cover an extremely wide workload.
The PM200 Pressure Measurement Modules use a highly
characterized silicon pressure
sensor to provide an economical
method of making accurate pressure measurements. The 0.02 %
FS specification includes the short
term performance of the module
(linearity, hysteresis, and repeatability) as well as its long term
stability and the uncertainty of the
calibration standard. Users can be
confident in the PM200 measurement performance.
Wide rangeability
assures wide workload
The Pressure Control Module can
handle a wide range of pressures.
The 6270A features pulsewidth-modulated control, a proven
technology that enables it to deliver
wide rangeability, the ratio of the
maximum to the minimum specified
measured value at which the instrument performs correctly. A wide
rangeability is what enables you to
calibrate a wide workload.
Safety features
protect operators
and instruments
Each measurement and control
module, as well as the main chassis, has pressure relief valves to
protect the instrument and its
operators from accidental overpressure. The 6270A has been designed
using Sound Engineering Practices
(SEP). With the internal relief
valves, user-setable pressure limits,
and emergency abort button, safety
is the highest priority.
If your workload includes devices
that contain different substances
like water, oil, and gas, you could
be at risk for contamination—something getting into your system
that isn’t supposed to be there.
Contamination can clog a calibrator’s valves, wear out its parts, and
make it difficult to maintain pressure. If the contamination gets into
the sensor, it can actually change
the calibrator’s behavior and throw
off your readings. If contamination is a concern for you, order the
optional 6270A Contamination
Prevention System (CPS) to help
keep the calibrator’s valves clean
and free from debris.
The CPS provides an unprecedented level of protection by
maintaining uni-directional flow
away from the controller, a gravity
sump system, and a two-stage
filtering system.
Change modules in
about 20 seconds.
Modular configuration
gives you almost
unlimited flexibility
Install up to five pressure modules
in a single 6270A chassis, mixing
and matching module types and
ranges to get the combination
that best suits your needs. Buy
just what you need to calibrate
the pressure ranges in your current workload. Add modules later
as your workload grows and
You’ll always

track and tighten
the knob until you
hear it click into
place. The click tells you that the
module is safely in place; a special
“anti-torque” guard on the knob
prevents over-tightening. You
never have to wonder if you tightened it too much or not enough.
Modules are installed and uninstalled through the front of the
chassis. You can easily install and
remove both the measurement
modules and the control module
from the chassis, even if the
6270A is installed in a rack mount.
Each module uses an enhanced
face-seal design that has been
leak tested to pressures that are
three times higher than the maximum working pressure. You don’t
have to worry about a leak in the
system affecting your ability to
measure and control pressure.
So easy to maintain, you can do it in house
We designed the 6270A to be easy
to maintain, making your cost of
ownership very reasonable. We
publish a Service and Calibration
Manual with detailed instructions on how to replace valves and
components. An on-board screen
capture routine can be used for
troubleshooting help.
Control and measurement
modules are separate, allowing for
quick and easy repair. Just pull out
the module and replace it; no autotuning required. You can change
the pressure ranges just as easily
by installing a new module and
possibly changing the supply pressure. No need to send the 6270A
back to the factory.
The modules can be calibrated
inside or outside of the chassis
using the optional PMM Calibrator
Kit. Once calibrated, you can use
them in any 6270A chassis without
impacting the uncertainty of your
measurements. Modules can be
removed and replaced, easily; no
specialized tools required.
Every component in the system
is designed for simple, modular
replacement, from the front panel
to the rear pressure connections.
The main CPU board is located
on top of the 6270A. You can
replace it just by removing a handful of screws.
The pressure connectors on
the back of the 6270A are made
from anodized aluminum, a robust
material that stands up well to
normal usage. However, if threads
are stripped or there is galling
from metal connectors sliding
against it, you can easily remove
the block without having to open
the chassis. Simply remove the
screws holding it in place and pull
it out. The block does not have any
items attached to it, so replacement
is simple and low cost.
The removable rear manifold
makes it easy to remove the 6270A
from a rack-mounted system.
Simply vent the test and supply
ports and disconnect the connection manifold from the back of the
chassis. You won’t need to question
which pressure line is the supply
port and which one is the test port;
they stay connected to the manifold, and the manifold can only be
connected one way. Three types of
manifolds—NPT, BSP, and 7/16-20
—are available to meet the needs
of different geographic regions.
The isolation valves on the main
manifolds are easily removed from
the top of the 6270A chassis.
Automation, training
and support
Automate with
COMPASS® software
for improved consistency and throughput
Fluke Calibration COMPASS for
Pressure software is designed
specifically for pressure calibration. It enables you to automate the
6270A and run complete pressure
calibration sequences on single or
multiple devices under test (DUTs).
COMPASS software removes the
unknowns often associated with
getting automated systems online.
The 6270A also features a full
remote interface that enables you
to use it with custom software or
other data acquisition equipment.
Details about the interface are provided in the 6270A User Manual.

* Uncertainty is the Instrumental Measurement Uncertainty (95%) and includes precision (linearity, hysteresis, and repeatability), temperature effects, 1 year stability, and reference uncertainty.
** Gauge mode uncertainty is the greater of the relative uncertainty and the threshold uncertainty.
** Absolute mode uncertainty is the greater of the relative uncertainty and the threshold uncertainty plus the absolute mode uncertainty adder for the lowest range PM600-AXXX module
installed. For example, if a PM600-A200K and a PM600-A2M, the uncertainty at 2000 kPa absolute would be 0.2 kPa (0.01% * 2000 kPa) plus 0.014 kPa.
