Introduction
The Fluke Calibration 6270A Pressure Controller/Calibrator (the Product)
precisely measures and controls pneumatic pressures up to 20 MPa (3000 psi).
Use the Product to calibrate, characterize, or test a wide variety of pressure
measurement devices that include transmitters, gauges, and switches.
The Product uses interchangeable Pressure Measurement Modules (PMMs) and
a Pressure Control Module (PCM) to regulate pressure output. The touchscreen
display features a multi-language user interface (UI). See Instrument Setup Menu
in the 6270A Operators Manual for more information.
This manual provides performance test, calibration adjustment, theory of
operation, troubleshooting, and repair procedures necessary to verify and
maintain Product performance.
The performance tests are based on the published 1-year specifications for the
Product. Fluke Calibration recommends the performance test as an acceptance
test when the Product is first received and later as a procedure to ensure that the
Product meets its published specifications. Fluke Calibration recommends a
1-year calibration cycle for the Product.
Use calibration adjustments to correct out-of-tolerance parameters so they meet
published specifications. If the Product fails the performance test, it is an
indication that the Product requires calibration adjustment and/or repair. While
calibration adjustment can be accomplished without removal of the covers, repair
requires access to the interior of the Product.
Environmental and warm up conditions required for the performance test and
calibration adjustments are stated at the beginning of each of the respective
sections.
Note
Repairs detailed in this manual are to the Modular-level only. Return
the Product to Fluke Calibration or take the Product to a local Fluke
Calibration Service Center for deeper-level repair.
