nVision Operation Manual • Page 1
Introduction
Thank you for choosing the nVision Reference Pressure Recorder from Crystal Engineering Corpo-
ration. Your nVision is a combination of leading edge technology and rugged industrial design.
Accuracy is up to 0.025 percent of reading - so any nVision can typically replace several gauges
or calibrators you may have been using. The nVision is fully temperature compensated - so there
is no change in accuracy throughout the entire operating temperature range!
The nVision features two identical bays allowing conguration of the reference recorder to meet
your requirements. All modules are eld-replaceable allowing you the exibility to react to
changing needs and module calibration requirements.
The nVision’s case is made from a rugged injection molded polymer utilizing a gasket to seal the
enclosure against dust and water intrusion. Even the mini USB B connector is fully sealed (with
or without the protective boot cover). Circuitry is mounted in a shock-absorbing elastomeric
system and the batteries are easily accessible by removing four captive screws.
Other features include:
•
Log and display 500,000 points at up to 10 readings
per second on up to two modules simultaneously
•
Interactive real-time graphing of measurements
•
ATEX / IECEx Scheme intrinsically safe
(nVision Reference Recorder only)
•
IP67 rated enclosure —1 meter immersion for 30
minutes (nVision Reference Recorder only)
