Using A Field Communicator; Using Ohmview 2000 Software On A Pc - Vega FiberFlex LFXG-H Operating Instructions Manual

Introduction

Using a field communicator

VEGA's gauge is compatible with the Emerson 375 Field Communicator or
equivalent.
To function, the minimum load resistance on the 4 ... 20 mA loop must be
250 . See the instruction manual for your field communicator for
information about:
• Key usage
• Data entry
• Equipment interface
To effectively use the gauge features, you must use VEGA's device description
(DD) to program the HART communicator. You can purchase a field
communicator, programmed with the DD, through VEGA (VEGA part number
244880).
Use firmware 2000.00 or higher when you use the field communicator to
use NORM or vapor compensation.
Note: There are some minor differences in operation of the Ohmview

Using Ohmview 2000 Software on a PC

When you use a PC with Windows and a Pentium processor to
communicate with the gauge or other VEGA HART transmitter field devices,
you must have a HART modem and the Ohmview 2000 software kit (part
number 243008), which includes:
• Modem
• Cables
• Software
Ohmview 2000, RS-485 Network, Ohmview 2000 Logger, and Ohmview
2000 Configurator software are Windows programs that emulate the Field
Communicator Model 375. Ohmview 2000:
• Charts the 4 ... 20 mA current output graphically

2000 software and the field communicator. Most significantly,
Ohmview 2000 software writes entries immediately to the
transmitter, but a field communicator must be manually told to
sends changes.
