Tips:
• Return to the Main Menu by pushing the left soft key several times.
• Carry spare batteries (5-AA) in the carrying case.
• A continuous measurement can display engineering units when linked to a Site/Sensor
with an engineering unit conversion applied.
• Leave 1–2 mm of exposed sensor wire on datalogger/multiplexer wiring for VWA
connection . Always disconnect automated system power prior to VWA connection.
Denitions:
Sensor: An individual vibrating wire sensor. A VWA can store up to 880
unique sensors (40 sites, 22 sensors/site).
Site: A project or geographic location containing up to 22 sensors.
User: Operator name and information.

If sensor wiring does not match the table, refer to the sensor manufacturer manual to determine the VW gage
wire leads. Some sensors may not have a thermistor or RTD (temperature measurement).

Vibrating wire leads are interchangeable (black and red instead of red and black); thermistor leads are similarly
interchangeable.
Read & Record
There are three options to save data when using Read & Record.
• Single is used when sensors won’t be repeatedly measured in the future (installation
record, baseline reading, troubleshooting).
• Site/Sensor is used when sensors will be repeatedly measured and data needs to be
linked to a site. Site/Sensor data is viewable in the eld for historical comparison.
• Continuous measures a single sensor at a user dened interval ranging from 1 second
to 15 minutes. Used to document installations, live eld testing (push-in-piezometer,
well pump test, sensor response, etc.), and for troubleshooting.
Notes:
• Measurements are not pressure or temperature compensated.
• Users can view all data. Sites are not user specic.
• See Measurement Screens for an explanation of displayed measurement results.
• Sites, Sensors, and Users can be created and edited either on the VWA, or with a PC and
keyboard using VwProjects.
Meet the Vibrating Wire Analyzer
Meet the Vibrating Wire Analyzer (VWA), the best vibrating wire (vw) eld reader
available. Field ready to quickly measure a sensor, save data, and communicate
results with custom PDF reports and spreadsheet output. Measurements are
geo-located with the integrated GPS allowing the VWA to verify locations and
walk you to your sensors. The large color display and VSPECT
TM
technology

create
condence that you are getting the best measurement possible both in the eld
and in the oce. , when your measurements matter.

Data Retrieval
Files are transferred to a PC from the VWA using the USB port . Measurement data collected
with the Read & Record option is saved as a PDF and/or CSV le. A printable report (PDF) com-
municates results quickly and professionally. Raw data les (CSV) can collect multiple sensors
(site) in a single le for additional spreadsheet analysis and reporting.
1 Export CSV les (optional)
• Navigate to the Main Menu. See Operation.
• Select Data. Choose and export CSV les.
2 Connect VWA to a PC with USB
• Connect a PC to the VWA with a USB Mini-B cable.
• Power is supplied through the USB-PC connection.
3 Copy les to PC
• Find the USB ash memory device (VWA) on the PC.
• Data les are stored in either the PDF Reports or CSV Data folder.
• Copy les to the PC.
PDF • Ready to print PDF reports
Reports • Field documentation
CSV • Multiple measurements in one le
Data • Spreadsheet analysis
4 Eject VWA from PC
• Eject the VWA from the PC prior to disconnecting the USB cable.
VwProjects
VwProjects is a free software package for easier setup of Sites, Sensors, and Users with a PC.
VwProjects can be downloaded and installed from the VWA memory or from the internet, see
Downloads.
VwProjects is used to create and edit a project le that contains information about Sites, Sen-
sors, and Users. Project les can be used to back up or transfer information to other VWA devices.
See Using VwProjects for details about creating, editing, and transferring project les.
Notes:
• A project le contains information about Sites, Sensors, and Users. Measurement
data is saved in the PDF and CSV les, and is NOT saved or transferred in a project
le.
• You can preview a report title block when creating or editing a user in
VwProjects.
File Types
The following les are created or used with the VWA. Files are transferred with a USB connection
(see Data Retrieval).
PDF: Measurement Reports created using Read & Record.
CSV: Created by the VWA with Read & Record, use for further spreadsheet analysis; see
Data Retrieval.
VWA: A project le contains information about Users, Sites, and Sensors. Created in the
VWA or with VwProjects.
OBJ: Operating system le, created by Campbell Scientic. See Downloads.
