Introduction
The 2271A Automated Pressure Calibrator (the Product) precisely measures and
controls pneumatic pressures in the range of -96.5 kPa to 20 MPa (-14.2 psi to
3,000 psi). Combine this functionality with the built-in Electrical Measurement
Module (EMM) with HART capabilities to accomplish closed loop calibration on
4-20 mA devices such as smart transmitters and analog transmitters.
Additionally, use the Product to calibrate or test a wide variety of pressure
measurement devices that include transmitters, gauges, and switches.
The Product features:
• Multi-language user interface (UI): English, Italian, Spanish, Russian,
Portuguese, Simplified Chinese, German, Japanese, French, or Korean.
• PM200 Pressure Measurement Modules (PMMs) compatibility - The PMMs
can be easily removed from the front of the Product to quickly change ranges.
The Product can operate in gauge, absolute, or tare mode. See the
Measurement Modes section.
• EM300 Electrical Measurement Module (EMM) - The EMM supplies 24 V dc
loop power, measure mA, and measure V dc. The EMM has a built-in 250 Ω
resistor that can be toggled on or off, eliminating the need to have an external
resistor to enable HART communication. Basic HART communicator
functions are also available when used with HART-capable transmitters. See
the HART Operation section.
• Closed-loop Calibration Programs - Automated, built-in, for pressure devices
that output mA signals from 0 mA to 30 mA.
• Dual test ports on top of the Product with hand-tight fittings for easy mounting
of Units Under Test (UUTs). A reference port is also located on top of the
Product for applications that require an atmospheric reference.
• Compatibility with the Fluke CPS-20M Contamination Prevention System that
will keep moisture, dirt, oil, grease, and other contaminants from damaging
the Product. See the CPS Use section. This allows for UUTs that are used in
processing applications or oil applications to be calibrated using a gas
medium.
• Compatibility with COMPASS for pressure.
• PC communication using Ethernet, USB, or a serial connection.
