Friendly Display
The PPI’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 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 PPI easy to use. Frequently used selections
such as the units of measure are restored to memory each time the PPI powers up.
Modular Design
The sensing element, pneumatics, electronics, and user interface are separated into
modules, making maintenance faster and easier.
Attractive Desktop Packaging
A sturdy aluminum case houses all of the PPI’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 PPI quickly tests its hardware and software. After the PPI completes
this test, the user can select more extensive self-tests for the pneumatics and electronics.
Ease of Calibration
Calibration may be performed either remotely or entirely from the front panel. No
disassembly is required, and there are no potentiometers to tune. On single sensor units,
only a three-point calibration is required to fully characterize the instrument. On
instruments that integrate multiple ranges such as the 7050i and 7050LP, additional
calibration points are required.
Automatic Zero Adjust
At the user’s request, the PPI’s software automatically performs the zero adjustment, with
no potentiometers to tune.
Automatic Head Correction
The PPI automatically corrects for head pressure between the PPI 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 PPI is not sensitive to the type of gas used within the system, the user can
select either instrumentation air or nitrogen, allowing the PPI 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. Altitude and airspeed units include feet, meters, knots, and kilometers per hour. In
addition to these predefined units, four user-defined units are programmable.
