RUSKA 7350

Users Manual

Ease of Operation

An intuitive, menu-driven interface makes the RUSKA 7350 easy to use. Frequently used selections, such as the units of measure, are stored in memory each time the RUSKA 7350 powers up.

Easily Programmable

The RUSKA 7350’s powerful microprocessor provides the basis for smart electronics. With a few simple keystrokes, the user set limits on the system pressure, create unique units of measure, program a test sequence, and more.

Attractive Desktop Packaging

A sturdy aluminum case houses all of the RUSKA 7350’s pneumatics, electronics, and user controls. With the optional rack mount kit, this standard 19" EIA chassis fits easily into a rack mount system.

Power-On Self Test

Upon power-up, the RUSKA 7350 quickly tests its hardware and software. After the RUSKA 7350 completes this test, the user can select more extensive self-tests for the pneumatics and electronics.

Ease of Calibration

A four-point calibration can be performed either remotely or entirely from the front panel. No disassembly is required, and there are no potentiometers to tune.

Automatic Zero Adjust

At the user’s request, the RUSKA 7350’s software automatically performs the zero adjustment, with no potentiometers to tune.

Automatic Head Correction

The RUSKA 7350 automatically corrects for head pressure between the RUSKA 7350 and the device under test (DUT), taking into account the density of the test gas.

Choice of Medium

The Pneumatic RUSKA 7350 can be used with any dry, clean nitrogen as the pressure medium.

Choice of Display Units

Standard units include inches of mercury at 0 °C and 60 °C, kiloPascals, bars, pounds per square inch, inches of water at 4 °C, 20 °C, and 25 °C, kilograms per square centimeter, millimeters of mercury, centimeters of mercury at 0 °C, and centimeters of water at 4 °C. Altitude and airspeed units include feet, meters, knots, and kilometers/hour. In addition to these predefined units, four user-defined units are programmable.

Communications Interface

The RUSKA 7350 includes standard RS-232 serial and IEEE-488 interfaces. The user’s computer communicates with the RUSKA 7350 through the Standard Commands for Programmable Instruments (SCPI) protocol. The RUSKA 7350 can also be configured to accept existing software written for the RUSKA Series 6000 DPG.
