a. Frequency reading of each sensor will correspond to the frequency
range specified by the sensor manufacturer.
b. No faults are indicated. If faults are indicated ( Diagnostic Bits does
not equal 0x00 , measurement results are in red type, or cells are
shaded red), consult Section 7.12.2.1, Monitoring with DVWTool
Software , for troubleshooting help.
6.2 Field-Mode Installation
IMPORTANT — Do not connect the CDM-VW300 analyzer or SC-CPI interface

Consult Section 7.1.1, Software and Driver Installation, for more information.
A simple field-mode configuration, using one CDM-VW300, is covered in this
section. Additional details concerning field-mode configuration and daisy-
chaining power and RJ45 connections are discussed in Section 7,
System
Operation . Capacity of the power supply is a critical element of field
installations. Most field-mode installations will require continuous ac power or
large solar panels and batteries.
