The program will function over sample rates per channel ranging from 2.5 to 20 samples per second. Filter coefficients are automatically set as a function of sample rate. One the useful features of this program is its ability to display filtered seismic data as the raw data is being recorded. When a file currently open for recording is selected, the heliplot is updated as often as new data is recorded to the file (every 256 data samples). The user has almost instant knowledge of a seismic event when it occurs. The ability to examine the detailed waveform plot is retained as well.

We use a slightly modified WWVB-controlled wall clock (Atomix brand supplied by Chaney Instrument Company) to generate accurate one-minute marks on our recordings. We have attached a small aluminum foil reflector to the second hand. An external LED source and phototransister assembly is used to detect passage of the second hand past the even minute time. The HeliPlot detailed waveform display shows the marks as vertical blue lines. Most of the time, the wall clock is very accurate. At certain times of the day, it goes through an alignment routine with the WWVB signal.

The spectral response of a filter can be measured by saving the filtered impulse as a file, and using the DFT function in the Windaq Waveform browser.NOTES: Excluding the seismometer and its amplifier, the data acquisition hardware and software cost was minimal. The 12-bit Dataq DI-158U A/D is sold for $99, complete with very good software and documentation. The wall clock is $30. The electrical hardware for picking off the time signals cost about $10. The Visual Basic software for writing this program was $109. For waveform study, the Dataq waveform browser furnished with the A/D is to be preferred over this heliplot program.------------------ To view entire plotting area, screen size must be set to 1024 by 768 pixels.------------------ This program is written in Visual Basic 6.0, and may not run on your machine.
