Working with Responses to Get Units of Ground Motion

Necessary information:

Sensor: sensitivity and passband (velocity transducer) or scaling (accelerometer)

For information on sensor sensitivity and passband, see the Sensor Comparison Chart along with the Sensor Response Plot.

Datalogger: Analog-to-Digital (A/D) conversion factor (aka bit weight) and Gain 

Quanterra model Q330: 419,430 counts/volt, or 2.384 uV/count at a Gain of 1 RefTek model RT130: 629,327 counts/volt, or 1.58997 uV/count at a Gain of 1

 

Example: Counts to Ground Velocity Conversion within the Passband

New Year, New Deployments!

The EPIC is getting the New Year off to a bang with the Pearl Hot Springs active source experiment.  The Pearl Hot Springs experiment is a multidisciplinary study to explore the Basin and Range normal faulting in the area near Silverpeak, NV (see map). The Principal Investigator, Katie Keranen from the University of Oklahoma, along with her collaborators, Randy Keller, OU and Daniel Stockli, University of Kansas, planned Geologic mapping of the area, a Magnetic Survey, a GPS Survey and possibly a Ground Penetrating Radar survey to accompany the Seismic Study.  The PIC Texans and geophones were used for 2 active source seismic deployments within the Pearl Hot Springs experiment.

New Web Organization

Our website has been reorganized! It may look the same at first glance, but take a closer look. The tabs and navigation menu are now more closely aligned with the EPIC working groups. There are a couple of new topics as well. This should make it much easier to quickly access the specific information you're looking for.

Loading Programs From Laptop to Q330's

 

 

Open the Windows control panel by pushing start button and then Settings and Control Panel.

 

 

 

Look under Ports (COM & LPT) to find the available com port numbers. In this picture we know that it is the “Keyspan” on COM 4 because we were using a Keyspan adapter.

 

If the Dataless Station panel appears select No. Otherwise proceed to the next step.

Loading Programs From a Clie To RT130's

This page is meant as a quick reference guide for using the Clié program "PFC-130" to load configuration parameters to a RT130. When deploying RT130's in the field, you will be provided an installation worksheet which covers the same steps but with more detail specific to your experiment.

Basic Guide for Loading Parameters to a RT130 from a Clié

1. Open PFC-130, on the Clié

2. Select Work with Configuration

3. Load (Load Configuration Pre-Written or Loaded Config File)

4. Select OK

5. Verify Configuration Name top of screen

6. Send to DAS

7. Select OK

8. Select Done

9. Re-Enter Work with Configuration

10. Select from DAS (Load from DAS)

11. Edit

12. Confirm Experiment Name
