Includes probe dia.] Includes interface electronics for computer Includes software for your computer Attaches to usb port Display wave form on oscilloscope Display frequency on spectrogram Display power level in rms, peak to peak & db/watts per cm2 Record all displays as files Transient recorder for tracking process Lap top computer compatible Map power levels in tank Check effect of baskets on work load Check transducers for operation Check effects of filtration on ultrasonic power Check power intensity levels between tanks The l-2001 software displays the following information: A. Wave form; the ultrasonic wave form is displayed on an on screen oscilloscope B. Frequency; the frequency [major and secondary] are displayed along with relative power on the spectrogram screen. A set of cursors may be placed on the screen and a small box will show the relative frequency and strength of that frequency. C. Power; the voltage meter screen has three windows that will show the rms of the ultrasonic power, the peak to peak power, and the power expressed in db/m watts. All three of the readings are displayed at the same time. D. Transient recorder; the transient recorder will allow you to make a continuous record of the power in the tank over a long period of time. E. The oscilloscope, spectrogram, and power meter readings may be saved as files and recalled and played for later analysis F. You may display the oscilloscope, spectrogram and voltage meter all at the same time. The transient recorder operates separately. G. Information on power levels may be imported to a spreadsheet for graphic analysis. H. Screen shots may be saved as jpeg files and all files and screen shots can be annotated with on screen comments. I. All data files may be recalled and placed in comparison mode for comparison to new readings
