This comprehensive Windows based data acquisition and analysis program, suitable for 64 analogue input channels, is project based and is split into three sections.
Calibration and scaling of inputs
The calibration section allows the modeller to calibrate any instruments installed in physical models that require regular in-situ calibration, such as resistance type wave probes. It also allows the modeller to enter factory calibrations for other sensors such as pressure sensors.
This section creates calibration files for use with the acquisition and analysis sections. It provides a comprehensive set of facilities for setting up the calibration files that are used to convert the analogue voltage signals in the model, to data at full scale, assuming Froude or Reynolds scaling.
HR DAQ is set to collect raw data for a specified period of time at a specified frequency.
After the data has been collected, HR DAQ can be used to perform a number of analysis routines. The principal analysis program includes two routines; one is a Fast Fourier Transform spectral analysis and the other a statistical one.
