Universal Power Supply
The Calibrator’s universal power supply accepts AC voltages between 100 – 120 VAC
and 220 – 240 VAC. To “reconfigure” the Calibrator for use in another country, the user
simply changes the power cord.
Measure While Control
The Calibrator simultaneously digitally displays the commanded pressure, the actual
pressure, and the difference between the two. A bar graph indicates how close the actual
pressure is to the commanded pressure, as well as how close the commanded pressure is
to the Calibrator’s full scale pressure.
Friendly Display
The Calibrator’s color active matrix TFT display combines a bright, low-glare readout
with a wide viewing angle. During normal operation, the measured pressure is easily
visible from a distance of 10 ranges such as the RUSKA 7252i, additional calibration
points are required.
Automatic Zero Adjust
At the user’s request, the Calibrator’s software automatically performs the zero
adjustment, with no potentiometers to tune.
Automatic Head Correction
The Calibrator automatically corrects for head pressure between the Calibrator and the
device under test (DUT), taking into account the density of the test gas; e.g., air or
nitrogen.
Choice of Medium
Although the Calibrator is not sensitive to the type of gas used within the system, the user
can select either instrumentation air or nitrogen, allowing the Calibrator to automatically
make pressure head corrections.
Choice of Display Units
Standard units include inHg at 0 °C and 60 °F, kiloPascals, bars, psi, inH
2
O at 4 °C,
20 °C, and 25 °C, kilograms per square centimeter, mmHg, cmHg at 0 °C, and cmH
2
O at
4 °C feet (3 meters).
Adjustable Pressure Display
The pressure display may be adjusted to show one decimal greater than or less than the
default resolution.
Ease of Operation
An intuitive, menu-driven interface makes the Calibrator easy to use. Frequently used
selections such as the units of measure are restored to memory each time the Calibrator
powers up.
Easily Programmable
The Calibrator’s powerful microprocessor provides the basis for smart electronics. With a
few simple keystrokes, the user can set limits on the system pressure, create unique units
of measure, program a test sequence, and more.
Modular Design
The sensing element, pneumatics, electronics, and user interface are separated into
modules, making maintenance faster and easier.
