By combining these sensors with microprocessor-based circuitry, an even higher degree of operational accuracy
and precision has been accomplished. For example, computer-generated correction curves for both the
non-linearity and the hysteresis of the sensors improve these characteristics by an order of magnitude or more.
Two micro-metering valves and vernier are provided to control the external nitrogen source while the digital
display indicates the magnitude of the applied test pressure. Also, a push-button switch provides the “zeroing” of
the pressure display (on GAGE models). Over-pressure protection, based on model, is provided via a fully
adjustable pressure regulator which is manually set for each new device being tested.
