C.1 Introduction
The PanaView™ graphical user interface offers interactive communications between
Windows-based PCs and Panametrics instruments compatible with the company’s
IDM protocol, such as the GC868 ultrasonic gas flowmeter. PanaView is compatible
with 32-bit Windows operating systems such as Windows 98SE, NT 4.0 (with Service
Pack 6), 2000, XP and ME. With PanaView, you can:
• load and save site file data
• create and save graph and log files
• display text output and graphs of live measurement data
• create custom templates for displaying text, graph and log data
• interface with multiple Panametrics instruments.
This document focuses on particular applications suitable for the GC868. For general
PanaView applications such as creating graph and log files, displaying live
measurement data, and creating custom templates, please refer to the general
PanaView User’s Manual (910-211).
