CDM-VW300 Series Dynamic Vibrating-Wire Analyzers
22
CDM-VW300 and CDM-VW305 programs use the following CRBasic
instructions:
CDM_VW300Config()
CDM_VW300Dynamic()
CDM_VW300Static()
The CRBasic program must be enabled specifically for the CDM-VW300 or
the CDM-VW305. Programs enabled for a CDM-VW300 use a
DeviceType
argument of 0 in the CDM_VW300Config() instruction. Programs enabled
for a CDM-VW305 use a DeviceType of 1 . Check that other settings
recorded in step 2 are integrated into the CRBasic program.
Do not attempt to use a program written for the CDM-VW300 when
using a CDM-VW305. Configurations for a particular analyzer are
deeply rooted in the CRBasic program. Simply changing the
DeviceType argument will not make all the necessary changes.
The following figure points out essential elements of the CRBasic program
for a datalogger controlling a CDM-VW300.
To simply confirm that readings can be obtained, one of the following
example programs can be used. These programs measure only basic
frequency:

Appendix G.1.1, 20 Hz Measurement Example – One CDM-VW300,
Two Channels

Appendix G.1.2, 20 Hz Measurement Example – One CDM-VW305,
Eight Channels
10. Send the CRBasic program to the datalogger using the program Send
command in the datalogger support software ( RTDAQ , LoggerNet , or
PC400 ).
