● High accuracy - Model 9116 pressure scanners are capable of accuracies up to
±0.05%. Accuracy is maintained through use of built-in re-zero, span, or multi-point
calibration capabilities. Accuracies are maintained for six (6) months after calibration.
● Low thermal errors - each internal transducer contains an individual
temperature sensor and thermal calibration data for internal use by software
correction algorithms. Thermal errors are reduced as low as ±0.001%FS/ºC over
the calibrated temperature span.
● Re-zero upon demand - an integrated calibration valve allows for automatic re-
zero adjustment calibration of dry gas transducers to null offset drift errors.
● Ease of transducer replacement - factory calibrated transducer assemblies may
be stocked and rapidly replaced in the field. Storage of thermal coefficients
within the transducer allows for ‘plug and play’ transducer replacement.
● Ease of calibration - each Model 9116 module contains a pneumatic
calibration manifold and software commands to automatically perform re-zero,
span, and multi-point adjustment calibrations. New offset and gain coefficients
that result from the most recent calibration may be stored in non-volatile
transducer memory.
● Ease of use - modules have simple command sets and provide engineering units
output. They may interface directly to a desktop or laptop computer or they may
be interconnected into a large network controlled by many types of host
computers.
● Connectivity - use of industry-standard communications network protocols to
control and read data from NetScanner

1.2.1 Differences Between Models 9016 and 9116
The all new electronics of the Model 9116 reduces data acquisition noise and capture latency,
while actually improving channel settling time and boosting data throughput. Additionally, the
Ethernet interface has been upgraded to 10BaseT/100BaseT with half and full duplex
capabilities to provide significant flexibility in network configuration. The Ethernet interface is
completely auto-configuring, ensuring the best utilization of network capabilities, while ensuring
the maximum backward compatibility. The trigger circuitry has been upgraded to allow triggering
on positive, negative, or both transitions of the trigger signal. By configuring the Model 9116 to
trigger on both transitions, the Model 9116 can be integrated into existing systems, providing
twice the data throughput for most users, without modification to the system trigger circuit.
The firmware in the Model 9116 implements the Model 9016 command set further simplifying
use with existing systems. In fact, the Model 9116 can be configured to report its identity as a
Model 9016 to ensure compatibility with system software that is sensitive to the reported model
type.
